# terser-webpack-plugin
This plugin uses [terser](https://github.com/terser-js/terser) to minify your JavaScript.
## Getting Started
To begin, you'll need to install `terser-webpack-plugin`:
```console
$ npm install terser-webpack-plugin --save-dev
```
Then add the plugin to your `webpack` config. For example:
**webpack.config.js**
```js
const TerserPlugin = require('terser-webpack-plugin');
module.exports = {
optimization: {
minimize: true,
minimizer: [new TerserPlugin()],
},
};
```
And run `webpack` via your preferred method.
## Options
### `test`
Type: `String|RegExp|Array<String|RegExp>`
Default: `/\.m?js(\?.*)?$/i`
Test to match files against.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
test: /\.js(\?.*)?$/i,
}),
],
},
};
```
### `include`
Type: `String|RegExp|Array<String|RegExp>`
Default: `undefined`
Files to include.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
include: /\/includes/,
}),
],
},
};
```
### `exclude`
Type: `String|RegExp|Array<String|RegExp>`
Default: `undefined`
Files to exclude.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
exclude: /\/excludes/,
}),
],
},
};
```
### `cache`
> ⚠ Ignored in webpack 5! Please use https://webpack.js.org/configuration/other-options/#cache.
Type: `Boolean|String`
Default: `true`
Enable file caching.
Default path to cache directory: `node_modules/.cache/terser-webpack-plugin`.
> ℹ️ If you use your own `minify` function please read the `minify` section for cache invalidation correctly.
#### `Boolean`
Enable/disable file caching.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
cache: true,
}),
],
},
};
```
#### `String`
Enable file caching and set path to cache directory.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
cache: 'path/to/cache',
}),
],
},
};
```
### `cacheKeys`
> ⚠ Ignored in webpack 5! Please use https://webpack.js.org/configuration/other-options/#cache.
Type: `Function<(defaultCacheKeys, file) -> Object>`
Default: `defaultCacheKeys => defaultCacheKeys`
Allows you to override default cache keys.
Default cache keys:
```js
({
terser: require('terser/package.json').version, // terser version
'terser-webpack-plugin': require('../package.json').version, // plugin version
'terser-webpack-plugin-options': this.options, // plugin options
nodeVersion: process.version, // Node.js version
name: file, // asset path
contentHash: crypto.createHash('md4').update(input).digest('hex'), // source file hash
});
```
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
cache: true,
cacheKeys: (defaultCacheKeys, file) => {
defaultCacheKeys.myCacheKey = 'myCacheKeyValue';
return defaultCacheKeys;
},
}),
],
},
};
```
### `parallel`
Type: `Boolean|Number`
Default: `true`
Use multi-process parallel running to improve the build speed.
Default number of concurrent runs: `os.cpus().length - 1`.
> ℹ️ Parallelization can speedup your build significantly and is therefore **highly recommended**.
> ⚠️ If you use **Circle CI** or any other environment that doesn't provide real available count of CPUs then you need to setup explicitly number of CPUs to avoid `Error: Call retries were exceeded` (see [#143](https://github.com/webpack-contrib/terser-webpack-plugin/issues/143), [#202](https://github.com/webpack-contrib/terser-webpack-plugin/issues/202)).
#### `Boolean`
Enable/disable multi-process parallel running.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
parallel: true,
}),
],
},
};
```
#### `Number`
Enable multi-process parallel running and set number of concurrent runs.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
parallel: 4,
}),
],
},
};
```
### `sourceMap`
Type: `Boolean`
Default: `false` (see below for details around `devtool` value and `SourceMapDevToolPlugin` plugin)
**Works only with `source-map`, `inline-source-map`, `hidden-source-map` and `nosources-source-map` values for the [`devtool`](https://webpack.js.org/configuration/devtool/) option.**
Why?
- `eval` wraps modules in `eval("string")` and the minimizer does not handle strings.
- `cheap` has not column information and minimizer generate only a single line, which leave only a single mapping.
The plugin respect the [`devtool`](https://webpack.js.org/configuration/devtool/) and using the `SourceMapDevToolPlugin` plugin.
Using supported `devtool` values enable source map generation.
Using `SourceMapDevToolPlugin` with enabled the `columns` option enables source map generation.
Use source maps to map error message locations to modules (this slows down the compilation).
If you use your own `minify` function please read the `minify` section for handling source maps correctly.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
sourceMap: true,
}),
],
},
};
```
### `minify`
Type: `Function`
Default: `undefined`
Allows you to override default minify function.
By default plugin uses [terser](https://github.com/terser-js/terser) package.
Useful for using and testing unpublished versions or forks.
> ⚠️ **Always use `require` inside `minify` function when `parallel` option enabled**.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
terserOptions: {
myCustomOption: true,
},
// Can be async
minify: (file, sourceMap, minimizerOptions) => {
// The `minimizerOptions` option contains option from the `terserOptions` option
// You can use `minimizerOptions.myCustomOption`
const extractedComments = [];
// Custom logic for extract comments
const { map, code } = require('uglify-module') // Or require('./path/to/uglify-module')
.minify(file, {
/* Your options for minification */
});
return { map, code, extractedComments };
},
}),
],
},
};
```
### `terserOptions`
Type: `Object`
Default: [default](https://github.com/terser-js/terser#minify-options)
Terser minify [options](https://github.com/terser-js/terser#minify-options).
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
terserOptions: {
ecma: undefined,
parse: {},
compress: {},
mangle: true, // Note `mangle.properties` is `false` by default.
module: false,
output: null,
toplevel: false,
nameCache: null,
ie8: false,
keep_classnames: undefined,
keep_fnames: false,
safari10: false,
},
}),
],
},
};
```
### `extractComments`
Type: `Boolean|String|RegExp|Function<(node, comment) -> Boolean|Object>|Object`
Default: `true`
Whether comments shall be extracted to a separate file, (see [details](https://github.com/webpack/webpack/commit/71933e979e51c533b432658d5e37917f9e71595a)).
By default extract only comments using `/^\**!|@preserve|@license|@cc_on/i` regexp condition and remove remaining comments.
If the original file is named `foo.js`, then the comments will be stored to `foo.js.LICENSE.txt`.
The `terserOptions.output.comments` option specifies whether the comment will be preserved, i.e. it is possible to preserve some comments (e.g. annotations) while extracting others or even preserving comments that have been extracted.
#### `Boolean`
Enable/disable extracting comments.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
extractComments: true,
}),
],
},
};
```
#### `String`
Extract `all` or `some` (use `/^\**!|@preserve|@license|@cc_on/i` RegExp) comments.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
extractComments: 'all',
}),
],
},
};
```
#### `RegExp`
All comments that match the given expression will be extracted to the separate file.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
extractComments: /@extract/i,
}),
],
},
};
```
#### `Function<(node, comment) -> Boolean>`
All comments that match the given expression will be extracted to the separate file.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
extractComments: (astNode, comment) => {
if (/@extract/i.test(comment.value)) {
return true;
}
return false;
},
}),
],
},
};
```
#### `Object`
Allow to customize condition for extract comments, specify extracted file name and banner.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
extractComments: {
condition: /^\**!|@preserve|@license|@cc_on/i,
filename: (fileData) => {
// The "fileData" argument contains object with "filename", "basename", "query" and "hash"
return `${fileData.filename}.LICENSE.txt${fileData.query}`;
},
banner: (licenseFile) => {
return `License information can be found in ${licenseFile}`;
},
},
}),
],
},
};
```
##### `condition`
Type: `Boolean|String|RegExp|Function<(node, comment) -> Boolean|Object>`
Condition what comments you need extract.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
extractComments: {
condition: 'some',
filename: (fileData) => {
// The "fileData" argument contains object with "filename", "basename", "query" and "hash"
return `${fileData.filename}.LICENSE.txt${fileData.query}`;
},
banner: (licenseFile) => {
return `License information can be found in ${licenseFile}`;
},
},
}),
],
},
};
```
##### `filename`
Type: `String|Function<(string) -> String>`
Default: `[file].LICENSE.txt[query]`
Available placeholders: `[file]`, `[query]` and `[filebase]` (`[base]` for webpack 5).
The file where the extracted comments will be stored.
Default is to append the suffix `.LICENSE.txt` to the original filename.
> ⚠️ We highly recommend using the `txt` extension. Using `js`/`cjs`/`mjs` extensions may conflict with existing assets which leads to broken code.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
extractComments: {
condition: /^\**!|@preserve|@license|@cc_on/i,
filename: 'extracted-comments.js',
banner: (licenseFile) => {
return `License information can be found in ${licenseFile}`;
},
},
}),
],
},
};
```
##### `banner`
Type: `Boolean|String|Function<(string) -> String>`
Default: `/*! For license information please see ${commentsFile} */`
The banner text that points to the extracted file and will be added on top of the original file.
Can be `false` (no banner), a `String`, or a `Function<(string) -> String>` that will be called with the filename where extracted comments have been stored.
Will be wrapped into comment.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
extractComments: {
condition: true,
filename: (fileData) => {
// The "fileData" argument contains object with "filename", "basename", "query" and "hash"
return `${fileData.filename}.LICENSE.txt${fileData.query}`;
},
banner: (commentsFile) => {
return `My custom banner about license information ${commentsFile}`;
},
},
}),
],
},
};
```
## Examples
### Preserve Comments
Extract all legal comments (i.e. `/^\**!|@preserve|@license|@cc_on/i`) and preserve `/@license/i` comments.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
terserOptions: {
output: {
comments: /@license/i,
},
},
extractComments: true,
}),
],
},
};
```
### Remove Comments
If you avoid building with comments, use this config:
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
terserOptions: {
output: {
comments: false,
},
},
extractComments: false,
}),
],
},
};
```
### Custom Minify Function
Override default minify function - use `uglify-js` for minification.
**webpack.config.js**
```js
module.exports = {
optimization: {
minimize: true,
minimizer: [
new TerserPlugin({
// Uncomment lines below for cache invalidation correctly
// cache: true,
// cacheKeys: (defaultCacheKeys) => {
// delete defaultCacheKeys.terser;
//
// return Object.assign(
// {},
// defaultCacheKeys,
// { 'uglify-js': require('uglify-js/package.json').version },
// );
// },
minify: (file, sourceMap) => {
// https://github.com/mishoo/UglifyJS2#minify-options
const uglifyJsOptions = {
/* your `uglify-js` package options */
};
if (sourceMap) {
uglifyJsOptions.sourceMap = {
content: sourceMap,
};
}
return require('uglify-js').minify(file, uglifyJsOptions);
},
}),
],
},
};
```

## 8.7.1 (2021-04-26)
### Bug fixes
Stop handling `"use strict"` directives in ECMAScript versions before 5.
Fix an issue where duplicate quoted export names in `export *` syntax were incorrectly checked.
Add missing type for `tokTypes`.
## 8.7.0 (2021-12-27)
### New features
Support quoted export names.
Upgrade to Unicode 14.
Add support for Unicode 13 properties in regular expressions.
### Bug fixes
Use a loop to find line breaks, because the existing regexp search would overrun the end of the searched range and waste a lot of time in minified code.
## 8.6.0 (2021-11-18)
### Bug fixes
Fix a bug where an object literal with multiple `__proto__` properties would incorrectly be accepted if a later property value held an assigment.
### New features
Support class private fields with the `in` operator.
## 8.5.0 (2021-09-06)
### Bug fixes
Improve context-dependent tokenization in a number of corner cases.
Fix location tracking after a 0x2028 or 0x2029 character in a string literal (which before did not increase the line number).
Fix an issue where arrow function bodies in for loop context would inappropriately consume `in` operators.
Fix wrong end locations stored on SequenceExpression nodes.
Implement restriction that `for`/`of` loop LHS can't start with `let`.
### New features

# Acorn
A tiny, fast JavaScript parser written in JavaScript.
## Community
Acorn is open source software released under an
[MIT license](https://github.com/acornjs/acorn/blob/master/acorn/LICENSE).
You are welcome to
[report bugs](https://github.com/acornjs/acorn/issues) or create pull
requests on [github](https://github.com/acornjs/acorn). For questions
and discussion, please use the
[Tern discussion forum](https://discuss.ternjs.net).
## Installation
The easiest way to install acorn is from [`npm`](https://www.npmjs.com/):
```sh
npm install acorn
```
Alternately, you can download the source and build acorn yourself:
```sh
git clone https://github.com/acornjs/acorn.git
cd acorn
npm install
```
## Interface
**parse**`(input, options)` is the main interface to the library. The
`input` parameter is a string, `options` must be an object setting
some of the options listed below. The return value will be an abstract
syntax tree object as specified by the [ESTree
spec](https://github.com/estree/estree).
```javascript
let acorn = require("acorn");
console.log(acorn.parse("1 + 1", {ecmaVersion: 2020}));
```
When encountering a syntax error, the parser will raise a
`SyntaxError` object with a meaningful message. The error object will
have a `pos` property that indicates the string offset at which the
error occurred, and a `loc` object that contains a `{line, column}`
object referring to that same position.
Options are provided by in a second argument, which should be an
object containing any of these fields (only `ecmaVersion` is
required):
- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be
either 3, 5, 6 (or 2015), 7 (2016), 8 (2017), 9 (2018), 10 (2019),
11 (2020), 12 (2021), 13 (2022, partial support)
or `"latest"` (the latest the library supports). This influences
support for strict mode, the set of reserved words, and support
for new syntax features.
**NOTE**: Only 'stage 4' (finalized) ECMAScript features are being
implemented by Acorn. Other proposed new features must be
implemented through plugins.
- **sourceType**: Indicate the mode the code should be parsed in. Can be
either `"script"` or `"module"`. This influences global strict mode
and parsing of `import` and `export` declarations.
**NOTE**: If set to `"module"`, then static `import` / `export` syntax
will be valid, even if `ecmaVersion` is less than 6.
- **onInsertedSemicolon**: If given a callback, that callback will be
called whenever a missing semicolon is inserted by the parser. The
callback will be given the character offset of the point where the
semicolon is inserted as argument, and if `locations` is on, also a
`{line, column}` object representing this position.
- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing
commas.
- **allowReserved**: If `false`, using a reserved word will generate
an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher
versions. When given the value `"never"`, reserved words and
keywords can also not be used as property names (as in Internet
Explorer's old parser).
- **allowReturnOutsideFunction**: By default, a return statement at
the top level raises an error. Set this to `true` to accept such
code.
- **allowImportExportEverywhere**: By default, `import` and `export`
declarations can only appear at a program's top level. Setting this
option to `true` allows them anywhere where a statement is allowed,
and also allows `import.meta` expressions to appear in scripts
(when `sourceType` is not `"module"`).
- **allowAwaitOutsideFunction**: If `false`, `await` expressions can
only appear inside `async` functions. Defaults to `true` for
`ecmaVersion` 2022 and later, `false` for lower versions. Setting this option to
`true` allows to have top-level `await` expressions. They are
still not allowed in non-`async` functions, though.
- **allowSuperOutsideMethod**: By default, `super` outside a method
raises an error. Set this to `true` to accept such code.
- **allowHashBang**: When this is enabled (off by default), if the
code starts with the characters `#!` (as in a shellscript), the
first line will be treated as a comment.
- **locations**: When `true`, each node has a `loc` object attached
with `start` and `end` subobjects, each of which contains the
one-based line and zero-based column numbers in `{line, column}`
form. Default is `false`.
- **onToken**: If a function is passed for this option, each found
token will be passed in same format as tokens returned from
`tokenizer().getToken()`.
If array is passed, each found token is pushed to it.
Note that you are not allowed to call the parser from the
callback—that will corrupt its internal state.
- **onComment**: If a function is passed for this option, whenever a
comment is encountered the function will be called with the
following parameters:
- `block`: `true` if the comment is a block comment, false if it
is a line comment.
- `text`: The content of the comment.
- `start`: Character offset of the start of the comment.
- `end`: Character offset of the end of the comment.
When the `locations` options is on, the `{line, column}` locations
of the comment’s start and end are passed as two additional
parameters.
If array is passed for this option, each found comment is pushed
to it as object in Esprima format:
```javascript
{
"type": "Line" | "Block",
"value": "comment text",
"start": Number,
"end": Number,
// If `locations` option is on:
"loc": {
"start": {line: Number, column: Number}
"end": {line: Number, column: Number}
},
// If `ranges` option is on:
"range": [Number, Number]
}
```
Note that you are not allowed to call the parser from the
callback—that will corrupt its internal state.
- **ranges**: Nodes have their start and end characters offsets
recorded in `start` and `end` properties (directly on the node,
rather than the `loc` object, which holds line/column data. To also
add a
[semi-standardized](https://bugzilla.mozilla.org/show_bug.cgi?id=745678)
`range` property holding a `[start, end]` array with the same
numbers, set the `ranges` option to `true`.
- **program**: It is possible to parse multiple files into a single
AST by passing the tree produced by parsing the first file as the
`program` option in subsequent parses. This will add the toplevel
forms of the parsed file to the "Program" (top) node of an existing
parse tree.
- **sourceFile**: When the `locations` option is `true`, you can pass
this option to add a `source` attribute in every node’s `loc`
object. Note that the contents of this option are not examined or
processed in any way; you are free to use whatever format you
choose.
- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property
will be added (regardless of the `location` option) directly to the
nodes, rather than the `loc` object.
- **preserveParens**: If this option is `true`, parenthesized expressions
are represented by (non-standard) `ParenthesizedExpression` nodes
that have a single `expression` property containing the expression
inside parentheses.
**parseExpressionAt**`(input, offset, options)` will parse a single
expression in a string, and return its AST. It will not complain if
there is more of the string left after the expression.
**tokenizer**`(input, options)` returns an object with a `getToken`
method that can be called repeatedly to get the next token, a `{start,
end, type, value}` object (with added `loc` property when the
`locations` option is enabled and `range` property when the `ranges`
option is enabled). When the token's type is `tokTypes.eof`, you
should stop calling the method, since it will keep returning that same
token forever.
In ES6 environment, returned result can be used as any other
protocol-compliant iterable:
```javascript
for (let token of acorn.tokenizer(str)) {
// iterate over the tokens
}
// transform code to array of tokens:
var tokens = [...acorn.tokenizer(str)];
```
**tokTypes** holds an object mapping names to the token type objects
that end up in the `type` properties of tokens.
**getLineInfo**`(input, offset)` can be used to get a `{line,
column}` object for a given program string and offset.
### The `Parser` class
Instances of the **`Parser`** class contain all the state and logic
that drives a parse. It has static methods `parse`,
`parseExpressionAt`, and `tokenizer` that match the top-level
functions by the same name.
When extending the parser with plugins, you need to call these methods
on the extended version of the class. To extend a parser with plugins,
you can use its static `extend` method.
```javascript
var acorn = require("acorn");
var jsx = require("acorn-jsx");
var JSXParser = acorn.Parser.extend(jsx());
JSXParser.parse("foo(<bar/>)", {ecmaVersion: 2020});
```
The `extend` method takes any number of plugin values, and returns a
new `Parser` class that includes the extra parser logic provided by
the plugins.
## Command line interface
The `bin/acorn` utility can be used to parse a file from the command
line. It accepts as arguments its input file and the following
options:
- `--ecma3|--ecma5|--ecma6|--ecma7|--ecma8|--ecma9|--ecma10`: Sets the ECMAScript version
to parse. Default is version 9.
- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise.
- `--locations`: Attaches a "loc" object to each node with "start" and
"end" subobjects, each of which contains the one-based line and
zero-based column numbers in `{line, column}` form.
- `--allow-hash-bang`: If the code starts with the characters #! (as
in a shellscript), the first line will be treated as a comment.
- `--allow-await-outside-function`: Allows top-level `await` expressions.
See the `allowAwaitOutsideFunction` option for more information.
- `--compact`: No whitespace is used in the AST output.
- `--silent`: Do not output the AST, just return the exit status.
- `--help`: Print the usage information and quit.
The utility spits out the syntax tree as JSON data.
## Existing plugins
- [`acorn-jsx`](https://github.com/RReverser/acorn-jsx): Parse [Facebook JSX syntax extensions](https://github.com/facebook/jsx)

# find-cache-dir [![Coverage Status](https://codecov.io/gh/avajs/find-cache-dir/branch/master/graph/badge.svg)](https://codecov.io/gh/avajs/find-cache-dir/branch/master)
> Finds the common standard cache directory
The [`nyc`](https://github.com/istanbuljs/nyc) and [`AVA`](https://ava.li) projects decided to standardize on a common directory structure for storing cache information:
```sh
# nyc
./node_modules/.cache/nyc
# ava
./node_modules/.cache/ava
# your-module
./node_modules/.cache/your-module
```
This module makes it easy to correctly locate the cache directory according to this shared spec. If this pattern becomes ubiquitous, clearing the cache for multiple dependencies becomes easy and consistent:
```
rm -rf ./node_modules/.cache
```
If you decide to adopt this pattern, please file a PR adding your name to the list of adopters below.
## Install
```
$ npm install find-cache-dir
```
## Usage
```js
const findCacheDir = require('find-cache-dir');
findCacheDir({name: 'unicorns'});
//=> '/user/path/node-modules/.cache/unicorns'
```
## API
### findCacheDir(options?)
Finds the cache directory using the supplied options. The algorithm checks for the `CACHE_DIR` environmental variable and uses it if it is not set to `true`, `false`, `1` or `0`. If one is not found, it tries to find a `package.json` file, searching every parent directory of the `cwd` specified (or implied from other options). It returns a `string` containing the absolute path to the cache directory, or `undefined` if `package.json` was never found or if the `node_modules` directory is unwritable.
#### options
Type: `object`
##### name
*Required*\
Type: `string`
Should be the same as your project name in `package.json`.
##### files
Type: `string[] | string`
An array of files that will be searched for a common parent directory. This common parent directory will be used in lieu of the `cwd` option below.
##### cwd
Type: `string`\
Default `process.cwd()`
Directory to start searching for a `package.json` from.
##### create
Type: `boolean`\
Default `false`
If `true`, the directory will be created synchronously before returning.
##### thunk
Type: `boolean`\
Default `false`
If `true`, this modifies the return type to be a function that is a thunk for `path.join(theFoundCacheDirectory)`.
```js
const thunk = findCacheDir({name: 'foo', thunk: true});
thunk();
//=> '/some/path/node_modules/.cache/foo'
thunk('bar.js')
//=> '/some/path/node_modules/.cache/foo/bar.js'
thunk('baz', 'quz.js')
//=> '/some/path/node_modules/.cache/foo/baz/quz.js'
```
This is helpful for actually putting actual files in the cache!
## Tips
- To test modules using `find-cache-dir`, set the `CACHE_DIR` environment variable to temporarily override the directory that is resolved.

# find-up [![Build Status](https://travis-ci.org/sindresorhus/find-up.svg?branch=master)](https://travis-ci.org/sindresorhus/find-up)
> Find a file or directory by walking up parent directories
## Install
```
$ npm install find-up
```
## Usage
```
/
└── Users
└── sindresorhus
├── unicorn.png
└── foo
└── bar
├── baz
└── example.js
```
`example.js`
```js
const path = require('path');
const findUp = require('find-up');
(async () => {
console.log(await findUp('unicorn.png'));
//=> '/Users/sindresorhus/unicorn.png'
console.log(await findUp(['rainbow.png', 'unicorn.png']));
//=> '/Users/sindresorhus/unicorn.png'
console.log(await findUp(async directory => {
const hasUnicorns = await findUp.exists(path.join(directory, 'unicorn.png'));
return hasUnicorns && directory;
}, {type: 'directory'}));
//=> '/Users/sindresorhus'
})();
```
## API
### findUp(name, options?)
### findUp(matcher, options?)
Returns a `Promise` for either the path or `undefined` if it couldn't be found.
### findUp([...name], options?)
Returns a `Promise` for either the first path found (by respecting the order of the array) or `undefined` if none could be found.
### findUp.sync(name, options?)
### findUp.sync(matcher, options?)
Returns a path or `undefined` if it couldn't be found.
### findUp.sync([...name], options?)
Returns the first path found (by respecting the order of the array) or `undefined` if none could be found.
#### name
Type: `string`
Name of the file or directory to find.
#### matcher
Type: `Function`
A function that will be called with each directory until it returns a `string` with the path, which stops the search, or the root directory has been reached and nothing was found. Useful if you want to match files with certain patterns, set of permissions, or other advanced use-cases.
When using async mode, the `matcher` may optionally be an async or promise-returning function that returns the path.
#### options
Type: `object`
##### cwd
Type: `string`<br>
Default: `process.cwd()`
Directory to start from.
##### type
Type: `string`<br>
Default: `'file'`<br>
Values: `'file'` `'directory'`
The type of paths that can match.
##### allowSymlinks
Type: `boolean`<br>
Default: `true`
Allow symbolic links to match if they point to the chosen path type.
### findUp.exists(path)
Returns a `Promise<boolean>` of whether the path exists.
### findUp.sync.exists(path)
Returns a `boolean` of whether the path exists.
#### path
Type: `string`
Path to a file or directory.
### findUp.stop
A [`Symbol`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol) that can be returned by a `matcher` function to stop the search and cause `findUp` to immediately return `undefined`. Useful as a performance optimization in case the current working directory is deeply nested in the filesystem.
```js
const path = require('path');
const findUp = require('find-up');
(async () => {
await findUp(directory => {
return path.basename(directory) === 'work' ? findUp.stop : 'logo.png';
});
})();
```

# make-dir [![Build Status](https://travis-ci.org/sindresorhus/make-dir.svg?branch=master)](https://travis-ci.org/sindresorhus/make-dir) [![codecov](https://codecov.io/gh/sindresorhus/make-dir/branch/master/graph/badge.svg)](https://codecov.io/gh/sindresorhus/make-dir)
> Make a directory and its parents if needed - Think `mkdir -p`
## Advantages over [`mkdirp`](https://github.com/substack/node-mkdirp)
- Promise API *(Async/await ready!)*
- Fixes many `mkdirp` issues: [#96](https://github.com/substack/node-mkdirp/pull/96) [#70](https://github.com/substack/node-mkdirp/issues/70) [#66](https://github.com/substack/node-mkdirp/issues/66)
- 100% test coverage
- CI-tested on macOS, Linux, and Windows
- Actively maintained
- Doesn't bundle a CLI
- Uses the native `fs.mkdir/mkdirSync` [`recursive` option](https://nodejs.org/dist/latest/docs/api/fs.html#fs_fs_mkdir_path_options_callback) in Node.js >=10.12.0 unless [overridden](#fs)
## Install
```
$ npm install make-dir
```
## Usage
```
$ pwd
/Users/sindresorhus/fun
$ tree
.
```
```js
const makeDir = require('make-dir');
(async () => {
const path = await makeDir('unicorn/rainbow/cake');
console.log(path);
//=> '/Users/sindresorhus/fun/unicorn/rainbow/cake'
})();
```
```
$ tree
.
└── unicorn
└── rainbow
└── cake
```
Multiple directories:
```js
const makeDir = require('make-dir');
(async () => {
const paths = await Promise.all([
makeDir('unicorn/rainbow'),
makeDir('foo/bar')
]);
console.log(paths);
/*
[
'/Users/sindresorhus/fun/unicorn/rainbow',
'/Users/sindresorhus/fun/foo/bar'
]
*/
})();
```
## API
### makeDir(path, options?)
Returns a `Promise` for the path to the created directory.
### makeDir.sync(path, options?)
Returns the path to the created directory.
#### path
Type: `string`
Directory to create.
#### options
Type: `object`
##### mode
Type: `integer`\
Default: `0o777`
Directory [permissions](https://x-team.com/blog/file-system-permissions-umask-node-js/).
##### fs
Type: `object`\
Default: `require('fs')`
Use a custom `fs` implementation. For example [`graceful-fs`](https://github.com/isaacs/node-graceful-fs).
Using a custom `fs` implementation will block the use of the native `recursive` option if `fs.mkdir` or `fs.mkdirSync` is not the native function.

# p-limit
> Run multiple promise-returning & async functions with limited concurrency
## Install
```
$ npm install p-limit
```
## Usage
```js
const pLimit = require('p-limit');
const limit = pLimit(1);
const input = [
limit(() => fetchSomething('foo')),
limit(() => fetchSomething('bar')),
limit(() => doSomething())
];
(async () => {
// Only one promise is run at once
const result = await Promise.all(input);
console.log(result);
})();
```
## API
### pLimit(concurrency)
Returns a `limit` function.
#### concurrency
Type: `number`\
Minimum: `1`\
Default: `Infinity`
Concurrency limit.
### limit(fn, ...args)
Returns the promise returned by calling `fn(...args)`.
#### fn
Type: `Function`
Promise-returning/async function.
#### args
Any arguments to pass through to `fn`.
Support for passing arguments on to the `fn` is provided in order to be able to avoid creating unnecessary closures. You probably don't need this optimization unless you're pushing a *lot* of functions.
### limit.activeCount
The number of promises that are currently running.
### limit.pendingCount
The number of promises that are waiting to run (i.e. their internal `fn` was not called yet).
### limit.clearQueue()
Discard pending promises that are waiting to run.
This might be useful if you want to teardown the queue at the end of your program's lifecycle or discard any function calls referencing an intermediary state of your app.
Note: This does not cancel promises that are already running.
## FAQ
### How is this different from the [`p-queue`](https://github.com/sindresorhus/p-queue) package?
This package is only about limiting the number of concurrent executions, while `p-queue` is a fully featured queue implementation with lots of different options, introspection, and ability to pause the queue.

# p-limit [![Build Status](https://travis-ci.org/sindresorhus/p-limit.svg?branch=master)](https://travis-ci.org/sindresorhus/p-limit)
> Run multiple promise-returning & async functions with limited concurrency
## Install
```
$ npm install p-limit
```
## Usage
```js
const pLimit = require('p-limit');
const limit = pLimit(1);
const input = [
limit(() => fetchSomething('foo')),
limit(() => fetchSomething('bar')),
limit(() => doSomething())
];
(async () => {
// Only one promise is run at once
const result = await Promise.all(input);
console.log(result);
})();
```
## API
### pLimit(concurrency)
Returns a `limit` function.
#### concurrency
Type: `number`\
Minimum: `1`\
Default: `Infinity`
Concurrency limit.
### limit(fn, ...args)
Returns the promise returned by calling `fn(...args)`.
#### fn
Type: `Function`
Promise-returning/async function.
#### args
Any arguments to pass through to `fn`.
Support for passing arguments on to the `fn` is provided in order to be able to avoid creating unnecessary closures. You probably don't need this optimization unless you're pushing a *lot* of functions.
### limit.activeCount
The number of promises that are currently running.
### limit.pendingCount
The number of promises that are waiting to run (i.e. their internal `fn` was not called yet).
### limit.clearQueue()
Discard pending promises that are waiting to run.
This might be useful if you want to teardown the queue at the end of your program's lifecycle or discard any function calls referencing an intermediary state of your app.
Note: This does not cancel promises that are already running.
## FAQ
### How is this different from the [`p-queue`](https://github.com/sindresorhus/p-queue) package?
This package is only about limiting the number of concurrent executions, while `p-queue` is a fully featured queue implementation with lots of different options, introspection, and ability to pause the queue.

# p-locate [![Build Status](https://travis-ci.org/sindresorhus/p-locate.svg?branch=master)](https://travis-ci.org/sindresorhus/p-locate)
> Get the first fulfilled promise that satisfies the provided testing function
Think of it like an async version of [`Array#find`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/find).
## Install
```
$ npm install p-locate
```
## Usage
Here we find the first file that exists on disk, in array order.
```js
const pathExists = require('path-exists');
const pLocate = require('p-locate');
const files = [
'unicorn.png',
'rainbow.png', // Only this one actually exists on disk
'pony.png'
];
(async () => {
const foundPath = await pLocate(files, file => pathExists(file));
console.log(foundPath);
//=> 'rainbow'
})();
```
*The above is just an example. Use [`locate-path`](https://github.com/sindresorhus/locate-path) if you need this.*
## API
### pLocate(input, tester, [options])
Returns a `Promise` that is fulfilled when `tester` resolves to `true` or the iterable is done, or rejects if any of the promises reject. The fulfilled value is the current iterable value or `undefined` if `tester` never resolved to `true`.
#### input
Type: `Iterable<Promise | unknown>`
An iterable of promises/values to test.
#### tester(element)
Type: `Function`
This function will receive resolved values from `input` and is expected to return a `Promise<boolean>` or `boolean`.
#### options
Type: `Object`
##### concurrency
Type: `number`<br>
Default: `Infinity`<br>
Minimum: `1`
Number of concurrently pending promises returned by `tester`.
##### preserveOrder
Type: `boolean`<br>
Default: `true`
Preserve `input` order when searching.
Disable this to improve performance if you don't care about the order.

# path-exists [![Build Status](https://travis-ci.org/sindresorhus/path-exists.svg?branch=master)](https://travis-ci.org/sindresorhus/path-exists)
> Check if a path exists
NOTE: `fs.existsSync` has been un-deprecated in Node.js since 6.8.0. If you only need to check synchronously, this module is not needed.
While [`fs.exists()`](https://nodejs.org/api/fs.html#fs_fs_exists_path_callback) is being [deprecated](https://github.com/iojs/io.js/issues/103), there's still a genuine use-case of being able to check if a path exists for other purposes than doing IO with it.
Never use this before handling a file though:
> In particular, checking if a file exists before opening it is an anti-pattern that leaves you vulnerable to race conditions: another process may remove the file between the calls to `fs.exists()` and `fs.open()`. Just open the file and handle the error when it's not there.
## Install
```
$ npm install path-exists
```
## Usage
```js
// foo.js
const pathExists = require('path-exists');
(async () => {
console.log(await pathExists('foo.js'));
//=> true
})();
```
## API
### pathExists(path)
Returns a `Promise<boolean>` of whether the path exists.
### pathExists.sync(path)
Returns a `boolean` of whether the path exists.

# schema-utils
Package for validate options in loaders and plugins.
## Getting Started
To begin, you'll need to install `schema-utils`:
```console
npm install schema-utils
```
## API
**schema.json**
```json
{
"type": "object",
"properties": {
"option": {
"type": "boolean"
}
},
"additionalProperties": false
}
```
```js
import schema from "./path/to/schema.json";
import { validate } from "schema-utils";
const options = { option: true };
const configuration = { name: "Loader Name/Plugin Name/Name" };
validate(schema, options, configuration);
```
### `schema`
Type: `String`
JSON schema.
Simple example of schema:
```json
{
"type": "object",
"properties": {
"name": {
"description": "This is description of option.",
"type": "string"
}
},
"additionalProperties": false
}
```
### `options`
Type: `Object`
Object with options.
```js
import schema from "./path/to/schema.json";
import { validate } from "schema-utils";
const options = { foo: "bar" };
validate(schema, { name: 123 }, { name: "MyPlugin" });
```
### `configuration`
Allow to configure validator.
There is an alternative method to configure the `name` and`baseDataPath` options via the `title` property in the schema.
For example:
```json
{
"title": "My Loader options",
"type": "object",
"properties": {
"name": {
"description": "This is description of option.",
"type": "string"
}
},
"additionalProperties": false
}
```
The last word used for the `baseDataPath` option, other words used for the `name` option.
Based on the example above the `name` option equals `My Loader`, the `baseDataPath` option equals `options`.
#### `name`
Type: `Object`
Default: `"Object"`
Allow to setup name in validation errors.
```js
import schema from "./path/to/schema.json";
import { validate } from "schema-utils";
const options = { foo: "bar" };
validate(schema, options, { name: "MyPlugin" });
```
```shell
Invalid configuration object. MyPlugin has been initialised using a configuration object that does not match the API schema.
- configuration.optionName should be a integer.
```
#### `baseDataPath`
Type: `String`
Default: `"configuration"`
Allow to setup base data path in validation errors.
```js
import schema from "./path/to/schema.json";
import { validate } from "schema-utils";
const options = { foo: "bar" };
validate(schema, options, { name: "MyPlugin", baseDataPath: "options" });
```
```shell
Invalid options object. MyPlugin has been initialised using an options object that does not match the API schema.
- options.optionName should be a integer.
```
#### `postFormatter`
Type: `Function`
Default: `undefined`
Allow to reformat errors.
```js
import schema from "./path/to/schema.json";
import { validate } from "schema-utils";
const options = { foo: "bar" };
validate(schema, options, {
name: "MyPlugin",
postFormatter: (formattedError, error) => {
if (error.keyword === "type") {
return `${formattedError}\nAdditional Information.`;
}
return formattedError;
},
});
```
```shell
Invalid options object. MyPlugin has been initialized using an options object that does not match the API schema.
- options.optionName should be a integer.
Additional Information.
```
## Examples
**schema.json**
```json
{
"type": "object",
"properties": {
"name": {
"type": "string"
},
"test": {
"anyOf": [
{ "type": "array" },
{ "type": "string" },
{ "instanceof": "RegExp" }
]
},
"transform": {
"instanceof": "Function"
},
"sourceMap": {
"type": "boolean"
}
},
"additionalProperties": false
}
```
### `Loader`
```js
import { getOptions } from "loader-utils";
import { validate } from "schema-utils";
import schema from "path/to/schema.json";
function loader(src, map) {
const options = getOptions(this);
validate(schema, options, {
name: "Loader Name",
baseDataPath: "options",
});
// Code...
}
export default loader;
```
### `Plugin`
```js
import { validate } from "schema-utils";
import schema from "path/to/schema.json";
class Plugin {
constructor(options) {
validate(schema, options, {
name: "Plugin Name",
baseDataPath: "options",
});
this.options = options;
}
apply(compiler) {
// Code...
}
}
export default Plugin;

semver(1) -- The semantic versioner for npm
===========================================
## Install
```bash
npm install semver
````
## Usage
As a node module:
```js
const semver = require('semver')
semver.valid('1.2.3') // '1.2.3'
semver.valid('a.b.c') // null
semver.clean(' =v1.2.3 ') // '1.2.3'
semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
semver.gt('1.2.3', '9.8.7') // false
semver.lt('1.2.3', '9.8.7') // true
semver.minVersion('>=1.0.0') // '1.0.0'
semver.valid(semver.coerce('v2')) // '2.0.0'
semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
```
As a command-line utility:
```
$ semver -h
A JavaScript implementation of the https://semver.org/ specification
Copyright Isaac Z. Schlueter
Usage: semver [options] <version> [<version> [...]]
Prints valid versions sorted by SemVer precedence
Options:
-r --range <range>
Print versions that match the specified range.
-i --increment [<level>]
Increment a version by the specified level. Level can
be one of: major, minor, patch, premajor, preminor,
prepatch, or prerelease. Default level is 'patch'.
Only one version may be specified.
--preid <identifier>
Identifier to be used to prefix premajor, preminor,
prepatch or prerelease version increments.
-l --loose
Interpret versions and ranges loosely
-p --include-prerelease
Always include prerelease versions in range matching
-c --coerce
Coerce a string into SemVer if possible
(does not imply --loose)
--rtl
Coerce version strings right to left
--ltr
Coerce version strings left to right (default)
Program exits successfully if any valid version satisfies
all supplied ranges, and prints all satisfying versions.
If no satisfying versions are found, then exits failure.
Versions are printed in ascending order, so supplying
multiple versions to the utility will just sort them.
```
## Versions
A "version" is described by the `v2.0.0` specification found at
<https://semver.org/>.
A leading `"="` or `"v"` character is stripped off and ignored.
## Ranges
A `version range` is a set of `comparators` which specify versions
that satisfy the range.
A `comparator` is composed of an `operator` and a `version`. The set
of primitive `operators` is:
* `<` Less than
* `<=` Less than or equal to
* `>` Greater than
* `>=` Greater than or equal to
* `=` Equal. If no operator is specified, then equality is assumed,
so this operator is optional, but MAY be included.
For example, the comparator `>=1.2.7` would match the versions
`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
or `1.1.0`.
Comparators can be joined by whitespace to form a `comparator set`,
which is satisfied by the **intersection** of all of the comparators
it includes.
A range is composed of one or more comparator sets, joined by `||`. A
version matches a range if and only if every comparator in at least
one of the `||`-separated comparator sets is satisfied by the version.
For example, the range `>=1.2.7 <1.3.0` would match the versions
`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
or `1.1.0`.
The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
### Prerelease Tags
If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
it will only be allowed to satisfy comparator sets if at least one
comparator with the same `[major, minor, patch]` tuple also has a
prerelease tag.
For example, the range `>1.2.3-alpha.3` would be allowed to match the
version `1.2.3-alpha.7`, but it would *not* be satisfied by
`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
than" `1.2.3-alpha.3` according to the SemVer sort rules. The version
range only accepts prerelease tags on the `1.2.3` version. The
version `3.4.5` *would* satisfy the range, because it does not have a
prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
The purpose for this behavior is twofold. First, prerelease versions
frequently are updated very quickly, and contain many breaking changes
that are (by the author's design) not yet fit for public consumption.
Therefore, by default, they are excluded from range matching
semantics.
Second, a user who has opted into using a prerelease version has
clearly indicated the intent to use *that specific* set of
alpha/beta/rc versions. By including a prerelease tag in the range,
the user is indicating that they are aware of the risk. However, it
is still not appropriate to assume that they have opted into taking a
similar risk on the *next* set of prerelease versions.
Note that this behavior can be suppressed (treating all prerelease
versions as if they were normal versions, for the purpose of range
matching) by setting the `includePrerelease` flag on the options
object to any
[functions](https://github.com/npm/node-semver#functions) that do
range matching.
#### Prerelease Identifiers
The method `.inc` takes an additional `identifier` string argument that
will append the value of the string as a prerelease identifier:
```javascript
semver.inc('1.2.3', 'prerelease', 'beta')
// '1.2.4-beta.0'
```
command-line example:
```bash
$ semver 1.2.3 -i prerelease --preid beta
1.2.4-beta.0
```
Which then can be used to increment further:
```bash
$ semver 1.2.4-beta.0 -i prerelease
1.2.4-beta.1
```
### Advanced Range Syntax
Advanced range syntax desugars to primitive comparators in
deterministic ways.
Advanced ranges may be combined in the same way as primitive
comparators using white space or `||`.
#### Hyphen Ranges `X.Y.Z - A.B.C`
Specifies an inclusive set.
* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
If a partial version is provided as the first version in the inclusive
range, then the missing pieces are replaced with zeroes.
* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
If a partial version is provided as the second version in the
inclusive range, then all versions that start with the supplied parts
of the tuple are accepted, but nothing that would be greater than the
provided tuple parts.
* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
Any of `X`, `x`, or `*` may be used to "stand in" for one of the
numeric values in the `[major, minor, patch]` tuple.
* `*` := `>=0.0.0` (Any version satisfies)
* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
A partial version range is treated as an X-Range, so the special
character is in fact optional.
* `""` (empty string) := `*` := `>=0.0.0`
* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
#### Tilde Ranges `~1.2.3` `~1.2` `~1`
Allows patch-level changes if a minor version is specified on the
comparator. Allows minor-level changes if not.
* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
the `1.2.3` version will be allowed, if they are greater than or
equal to `beta.2`. So, `1.2.3-beta.4` would be allowed, but
`1.2.4-beta.2` would not, because it is a prerelease of a
different `[major, minor, patch]` tuple.
#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
Allows changes that do not modify the left-most non-zero element in the
`[major, minor, patch]` tuple. In other words, this allows patch and
minor updates for versions `1.0.0` and above, patch updates for
versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
Many authors treat a `0.x` version as if the `x` were the major
"breaking-change" indicator.
Caret ranges are ideal when an author may make breaking changes
between `0.2.4` and `0.3.0` releases, which is a common practice.
However, it presumes that there will *not* be breaking changes between
`0.2.4` and `0.2.5`. It allows for changes that are presumed to be
additive (but non-breaking), according to commonly observed practices.
* `^1.2.3` := `>=1.2.3 <2.0.0`
* `^0.2.3` := `>=0.2.3 <0.3.0`
* `^0.0.3` := `>=0.0.3 <0.0.4`
* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
the `1.2.3` version will be allowed, if they are greater than or
equal to `beta.2`. So, `1.2.3-beta.4` would be allowed, but
`1.2.4-beta.2` would not, because it is a prerelease of a
different `[major, minor, patch]` tuple.
* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4` Note that prereleases in the
`0.0.3` version *only* will be allowed, if they are greater than or
equal to `beta`. So, `0.0.3-pr.2` would be allowed.
When parsing caret ranges, a missing `patch` value desugars to the
number `0`, but will allow flexibility within that value, even if the
major and minor versions are both `0`.
* `^1.2.x` := `>=1.2.0 <2.0.0`
* `^0.0.x` := `>=0.0.0 <0.1.0`
* `^0.0` := `>=0.0.0 <0.1.0`
A missing `minor` and `patch` values will desugar to zero, but also
allow flexibility within those values, even if the major version is
zero.
* `^1.x` := `>=1.0.0 <2.0.0`
* `^0.x` := `>=0.0.0 <1.0.0`
### Range Grammar
Putting all this together, here is a Backus-Naur grammar for ranges,
for the benefit of parser authors:
```bnf
range-set ::= range ( logical-or range ) *
logical-or ::= ( ' ' ) * '||' ( ' ' ) *
range ::= hyphen | simple ( ' ' simple ) * | ''
hyphen ::= partial ' - ' partial
simple ::= primitive | partial | tilde | caret
primitive ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
partial ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
xr ::= 'x' | 'X' | '*' | nr
nr ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
tilde ::= '~' partial
caret ::= '^' partial
qualifier ::= ( '-' pre )? ( '+' build )?
pre ::= parts
build ::= parts
parts ::= part ( '.' part ) *
part ::= nr | [-0-9A-Za-z]+
```
## Functions
All methods and classes take a final `options` object argument. All
options in this object are `false` by default. The options supported
are:
- `loose` Be more forgiving about not-quite-valid semver strings.
(Any resulting output will always be 100% strict compliant, of
course.) For backwards compatibility reasons, if the `options`
argument is a boolean value instead of an object, it is interpreted
to be the `loose` param.
- `includePrerelease` Set to suppress the [default
behavior](https://github.com/npm/node-semver#prerelease-tags) of
excluding prerelease tagged versions from ranges unless they are
explicitly opted into.
Strict-mode Comparators and Ranges will be strict about the SemVer
strings that they parse.
* `valid(v)`: Return the parsed version, or null if it's not valid.
* `inc(v, release)`: Return the version incremented by the release
type (`major`, `premajor`, `minor`, `preminor`, `patch`,
`prepatch`, or `prerelease`), or null if it's not valid
* `premajor` in one call will bump the version up to the next major
version and down to a prerelease of that major version.
`preminor`, and `prepatch` work the same way.
* If called from a non-prerelease version, the `prerelease` will work the
same as `prepatch`. It increments the patch version, then makes a
prerelease. If the input version is already a prerelease it simply
increments it.
* `prerelease(v)`: Returns an array of prerelease components, or null
if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
* `major(v)`: Return the major version number.
* `minor(v)`: Return the minor version number.
* `patch(v)`: Return the patch version number.
* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
or comparators intersect.
* `parse(v)`: Attempt to parse a string as a semantic version, returning either
a `SemVer` object or `null`.
### Comparison
* `gt(v1, v2)`: `v1 > v2`
* `gte(v1, v2)`: `v1 >= v2`
* `lt(v1, v2)`: `v1 < v2`
* `lte(v1, v2)`: `v1 <= v2`
* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
even if they're not the exact same string. You already know how to
compare strings.
* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
the corresponding function above. `"==="` and `"!=="` do simple
string comparison, but are included for completeness. Throws if an
invalid comparison string is provided.
* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
`v2` is greater. Sorts in ascending order if passed to `Array.sort()`.
* `rcompare(v1, v2)`: The reverse of compare. Sorts an array of versions
in descending order when passed to `Array.sort()`.
* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions
are equal. Sorts in ascending order if passed to `Array.sort()`.
`v2` is greater. Sorts in ascending order if passed to `Array.sort()`.
* `diff(v1, v2)`: Returns difference between two versions by the release type
(`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
or null if the versions are the same.
### Comparators
* `intersects(comparator)`: Return true if the comparators intersect
### Ranges
* `validRange(range)`: Return the valid range or null if it's not valid
* `satisfies(version, range)`: Return true if the version satisfies the
range.
* `maxSatisfying(versions, range)`: Return the highest version in the list
that satisfies the range, or `null` if none of them do.
* `minSatisfying(versions, range)`: Return the lowest version in the list
that satisfies the range, or `null` if none of them do.
* `minVersion(range)`: Return the lowest version that can possibly match
the given range.
* `gtr(version, range)`: Return `true` if version is greater than all the
versions possible in the range.
* `ltr(version, range)`: Return `true` if version is less than all the
versions possible in the range.
* `outside(version, range, hilo)`: Return true if the version is outside
the bounds of the range in either the high or low direction. The
`hilo` argument must be either the string `'>'` or `'<'`. (This is
the function called by `gtr` and `ltr`.)
* `intersects(range)`: Return true if any of the ranges comparators intersect
Note that, since ranges may be non-contiguous, a version might not be
greater than a range, less than a range, *or* satisfy a range! For
example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
until `2.0.0`, so the version `1.2.10` would not be greater than the
range (because `2.0.1` satisfies, which is higher), nor less than the
range (since `1.2.8` satisfies, which is lower), and it also does not
satisfy the range.
If you want to know if a version satisfies or does not satisfy a
range, use the `satisfies(version, range)` function.
### Coercion
* `coerce(version, options)`: Coerces a string to semver if possible
This aims to provide a very forgiving translation of a non-semver string to
semver. It looks for the first digit in a string, and consumes all
remaining characters which satisfy at least a partial semver (e.g., `1`,
`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer
versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All
surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
`3.4.0`). Only text which lacks digits will fail coercion (`version one`
is not valid). The maximum length for any semver component considered for
coercion is 16 characters; longer components will be ignored
(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any
semver component is `Integer.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
components are invalid (`9999999999999999.4.7.4` is likely invalid).
If the `options.rtl` flag is set, then `coerce` will return the right-most
coercible tuple that does not share an ending index with a longer coercible
tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not
`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of
any other overlapping SemVer tuple.
### Clean
* `clean(version)`: Clean a string to be a valid semver if possible
This will return a cleaned and trimmed semver version. If the provided version is not valid a null will be returned. This does not work for ranges.
ex.
* `s.clean(' = v 2.1.5foo')`: `null`
* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'`
* `s.clean(' = v 2.1.5-foo')`: `null`
* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'`
* `s.clean('=v2.1.5')`: `'2.1.5'`
* `s.clean(' =v2.1.5')`: `2.1.5`
* `s.clean(' 2.1.5 ')`: `'2.1.5'`
* `s.clean('~1.0.0')`: `null`

## v5.3.1
- An issue with destructuring declarations when `pure_getters` is enabled has been fixed
- Fixed a crash when chain expressions need to be shallowly compared
- Made inlining functions more conservative to make sure a function that contains a reference to itself isn't moved into a place that can create multiple instances of itself.
## v5.3.0
- Fixed a crash when compressing object spreads in some cases
- Fixed compiletime evaluation of optional chains (caused typeof a?.b to always return "object")

- Optional dotted chains now accept keywords, just like dotted expressions (`foo?.default`)
## v5.2.0
- Optional chaining syntax is now supported.
- Consecutive await expressions don't have unnecessary parens
- Taking the variable name's length (after mangling) into consideration when deciding to inline
## v5.1.0
- `import.meta` is now supported
- Typescript typings have been improved
## v5.0.0
- `in` operator now taken into account during property mangle.
- Fixed infinite loop in face of a reference loop in some situations.
- Kept exports and imports around even if there's something which will throw before them.
- The main exported bundle for commonjs, dist/bundle.min.js is no longer minified.
## v5.0.0-beta.0

- BREAKING: Internal AST is no longer exposed, so that it can be improved without releasing breaking changes.
- BREAKING: Lowest supported node version is 10
- BREAKING: There are no more warnings being emitted
- Module is now distributed as a dual package - You can `import` and `require()` too.
- Inline improvements were made
-----
## v4.8.1 (backport)
- Security fix for RegExps that should not be evaluated (regexp DDOS)
## v4.8.0
- Support for numeric separators (`million = 1_000_000`) was added.
- Assigning properties to a class is now assumed to be pure.
- Fixed bug where `yield` wasn't considered a valid property key in generators.
## v4.7.0
- A bug was fixed where an arrow function would have the wrong size
- `arguments` object is now considered safe to retrieve properties from (useful for `length`, or `0`) even when `pure_getters` is not set.
- Fixed erroneous `const` declarations without value (which is invalid) in some corner cases when using `collapse_vars`.
## v4.6.13
- Fixed issue where ES5 object properties were being turned into ES6 object properties due to more lax unicode rules.
- Fixed parsing of BigInt with lowercase `e` in them.
## v4.6.12
- Fixed subtree comparison code, making it see that `[1,[2, 3]]` is different from `[1, 2, [3]]`
- Printing of unicode identifiers has been improved
## v4.6.11
- Read unused classes' properties and method keys, to figure out if they use other variables.
- Prevent inlining into block scopes when there are name collisions
- Functions are no longer inlined into parameter defaults, because they live in their own special scope.
- When inlining identity functions, take into account the fact they may be used to drop `this` in function calls.
- Nullish coalescing operator (`x ?? y`), plus basic optimization for it.
- Template literals in binary expressions such as `+` have been further optimized
## v4.6.10
- Do not use reduce_vars when classes are present
## v4.6.9
- Check if block scopes actually exist in blocks
## v4.6.8
- Take into account "executed bits" of classes like static properties or computed keys, when checking if a class evaluation might throw or have side effects.
## v4.6.7
- Some new performance gains through a `AST_Node.size()` method which measures a node's source code length without printing it to a string first.
- An issue with setting `--comments` to `false` in the CLI has been fixed.
- Fixed some issues with inlining
- `unsafe_symbols` compress option was added, which turns `Symbol("name")` into just `Symbol()`
- Brought back compress performance improvement through the `AST_Node.equivalent_to(other)` method (which was reverted in v4.6.6).
## v4.6.6
(hotfix release)
- Reverted code to 4.6.4 to allow for more time to investigate an issue.
## v4.6.5 (REVERTED)
- Improved compress performance through using a new method to see if two nodes are equivalent, instead of printing them to a string.
## v4.6.4
- The `"some"` value in the `comments` output option now preserves `@lic` and other important comments when using `//`
- `</script>` is now better escaped in regex, and in comments, when using the `inline_script` output option

- `/*#__NOINLINE__*/` annotation fixed for more use cases where inlining happens.
## v4.6.1
- Fixed an issue where a class is duplicated by reduce_vars when there's a recursive reference to the class.
## v4.6.0
- Fixed issues with recursive class references.
- BigInt evaluation has been prevented, stopping Terser from evaluating BigInts like it would do regular numbers.
- Class property support has been added
## v4.5.1
(hotfix release)
- Fixed issue where `() => ({})[something]` was not parenthesised correctly.
## v4.5.0
- Inlining has been improved
- An issue where keep_fnames combined with functions declared through variables was causing name shadowing has been fixed
- You can now set the ES version through their year
- The output option `keep_numbers` has been added, which prevents Terser from turning `1000` into `1e3` and such
- Internal small optimisations and refactors
## v4.4.3
- Number and BigInt parsing has been fixed
- `/*#__INLINE__*/` annotation fixed for arrow functions with non-block bodies.
- Functional tests have been added, using [this repository](https://github.com/terser/terser-functional-tests).
- A memory leak, where the entire AST lives on after compression, has been plugged.
## v4.4.2
- Fixed a problem with inlining identity functions
## v4.4.1
*note:* This introduced a feature, therefore it should have been a minor release.
- Fixed a crash when `unsafe` was enabled.
- An issue has been fixed where `let` statements might be collapsed out of their scope.
- Some error messages have been improved by adding quotes around variable names.
## v4.4.0
- Added `/*#__INLINE__*/` and `/*#__NOINLINE__*/` annotations for calls. If a call has one of these, it either forces or forbids inlining.
## v4.3.11
- Fixed a problem where `window` was considered safe to access, even though there are situations where it isn't (Node.js, workers...)
- Fixed an error where `++` and `--` were considered side-effect free
- `Number(x)` now needs both `unsafe` and and `unsafe_math` to be compressed into `+x` because `x` might be a `BigInt`
- `keep_fnames` now correctly supports regexes when the function is in a variable declaration
## v4.3.10
- Fixed syntax error when repeated semicolons were encountered in classes
- Fixed invalid output caused by the creation of empty sequences internally
- Scopes are now updated when scopes are inlined into them
## v4.3.9
- Fixed issue with mangle's `keep_fnames` option, introduced when adding code to keep variable names of anonymous functions
## v4.3.8
- Typescript typings fix
## v4.3.7
- Parsing of regex options in the CLI (which broke in v4.3.5) was fixed.
- typescript definition updates
## v4.3.6
(crash hotfix)
## v4.3.5
- Fixed an issue with DOS line endings strings separated by `\` and a new line.
- Improved fix for the output size regression related to unused references within the extends section of a class.
- Variable names of anonymous functions (eg: `const x = () => { ... }` or `var func = function () {...}`) are now preserved when keep_fnames is true.
- Fixed performance degradation introduced for large payloads in v4.2.0
## v4.3.4
- Fixed a regression where the output size was increased when unused classes were referred to in the extends clause of a class.
- Small typescript typings fixes.
- Comments with `@preserve`, `@license`, `@cc_on` as well as comments starting with `/*!` and `/**!` are now preserved by default.
## v4.3.3
- Fixed a problem where parsing template strings would mix up octal notation and a slash followed by a zero representing a null character.
- Started accepting the name `async` in destructuring arguments with default value.
- Now Terser takes into account side effects inside class `extends` clauses.
- Added parens whenever there's a comment between a return statement and the returned value, to prevent issues with ASI.
- Stopped using raw RegExp objects, since the spec is going to continue to evolve. This ensures Terser is able to process new, unknown RegExp flags and features. This is a breaking change in the AST node AST_RegExp.
## v4.3.2
- Typescript typing fix
- Ensure that functions can't be inlined, by reduce_vars, into places where they're accessing variables with the same name, but from somewhere else.
## v4.3.1
- Fixed an issue from 4.3.0 where any block scope within a for loop erroneously had its parent set to the function scopee
- Fixed an issue where compressing IIFEs with argument expansions would result in some parameters becoming undefined
- addEventListener options argument's properties are now part of the DOM properties list.
## v4.3.0
- Do not drop computed object keys with side effects
- Functions passed to other functions in calls are now wrapped in parentheses by default, which speeds up loading most modules
- Objects with computed properties are now less likely to be hoisted
- Speed and memory efficiency optimizations
- Fixed scoping issues with `try` and `switch`
## v4.2.1
- Minor refactors
- Fixed a bug similar to #369 in collapse_vars
- Functions can no longer be inlined into a place where they're going to be compared with themselves.
- reduce_funcs option is now legacy, as using reduce_vars without reduce_funcs caused some weird corner cases. As a result, it is now implied in reduce_vars and can't be turned off without turning off reduce_vars.
- Bug which would cause a random stack overflow has now been fixed.
## v4.2.0
- When the source map URL is `inline`, don't write it to a file.
- Fixed output parens when a lambda literal is the tag on a tagged template string.
- The `mangle.properties.undeclared` option was added. This enables the property mangler to mangle properties of variables which can be found in the name cache, but whose properties are not known to this Terser run.
- The v8 bug where the toString and source representations of regexes like `RegExp("\\\n")` includes an actual newline is now fixed.
- Now we're guaranteed to not have duplicate comments in the output
- Domprops updates
## v4.1.4
- Fixed a crash when inlining a function into somewhere else when it has interdependent, non-removable variables.
## v4.1.3
- Several issues with the `reduce_vars` option were fixed.
- Starting this version, we only have a dist/bundle.min.js
## v4.1.2
- The hotfix was hotfixed
## v4.1.1
- Fixed a bug where toplevel scopes were being mixed up with lambda scopes
## v4.1.0
- Internal functions were replaced by `Object.assign`, `Array.prototype.some`, `Array.prototype.find` and `Array.prototype.every`.
- A serious issue where some ESM-native code was broken was fixed.
- Performance improvements were made.
- Support for BigInt was added.
- Inline efficiency was improved. Functions are now being inlined more proactively instead of being inlined only after another Compressor pass.
## v4.0.2
(Hotfix release. Reverts unmapped segments PR [#342](https://github.com/terser/terser/pull/342), which will be put back on Terser when the upstream issue is resolved)
## v4.0.1
- Collisions between the arguments of inlined functions and names in the outer scope are now being avoided while inlining
- Unmapped segments are now preserved when compressing a file which has source maps
- Default values of functions are now correctly converted from Mozilla AST to Terser AST
- JSON ⊂ ECMAScript spec (if you don't know what this is you don't need to)
- Export AST_* classes to library users
- Fixed issue with `collapse_vars` when functions are created with the same name as a variable which already exists
- Added `MutationObserverInit` (Object with options for initialising a mutation observer) properties to the DOM property list
- Custom `Error` subclasses are now internally used instead of old-school Error inheritance hacks.
- Documentation fixes
- Performance optimizations
## v4.0.0
- **breaking change**: The `variables` property of all scopes has become a standard JavaScript `Map` as opposed to the old bespoke `Dictionary` object.
- Typescript definitions were fixed
- `terser --help` was fixed
- The public interface was cleaned up
- Fixed optimisation of `Array` and `new Array`
- Added the `keep_quoted=strict` mode to mangle_props, which behaves more like Google Closure Compiler by mangling all unquoted property names, instead of reserving quoted property names automatically.
- Fixed parent functions' parameters being shadowed in some cases
- Allowed Terser to run in a situation where there are custom functions attached to Object.prototype
- And more bug fixes, optimisations and internal changes
## v3.17.0
- More DOM properties added to --mangle-properties's DOM property list
- Closed issue where if 2 functions had the same argument name, Terser would not inline them together properly
- Fixed issue with `hasOwnProperty.call`
- You can now list files to minify in a Terser config file
- Started replacing `new Array(<number>)` with an array literal
- Started using ES6 capabilities like `Set` and the `includes` method for strings and arrays
## v3.16.1
- Fixed issue where Terser being imported with `import` would cause it not to work due to the `__esModule` property. (PR #254 was submitted, which was nice, but since it wasn't a pure commonJS approach I decided to go with my own solution)
## v3.16.0
- No longer leaves names like Array or Object or window as a SimpleStatement (statement which is just a single expression).
- Add support for sections sourcemaps (IndexedSourceMapConsumer)
- Drops node.js v4 and starts using commonJS
- Is now built with rollup
## v3.15.0
- Inlined spread syntax (`[...[1, 2, 3], 4, 5] => [1, 2, 3, 4, 5]`) in arrays and objects.
- Fixed typo in compressor warning
- Fixed inline source map input bug
- Fixed parsing of template literals with unnecessary escapes (Like `\\a`)
