+Type: `Object|Function`
 Default: `undefined`
 
-This property allows a user to pass custom HTTP headers on each request. eg.
-`{ "X-Custom-Header": "yes" }`
+This property allows a user to pass custom HTTP headers on each request.

+```js
+webpackDevMiddleware(compiler, {
+  headers: (req, res, context) => {
+    res.setHeader("Last-Modified", new Date());
+  },
+});
+```
 
 ### index
 
-Type: `String`  
-Default: `undefined`
+Type: `Boolean|String`  
+Default: `index.html`
 
-"index.html",
-// The index path for web server, defaults to "index.html".
-// If falsy (but not undefined), the server will not respond to requests to the root URL.
-
-### lazy
-
-Type: `Boolean`  
-Default: `undefined`
-
-This option instructs the module to operate in 'lazy' mode, meaning that it won't
-recompile when files change, but rather on each request.
-
-### logger
-
-Type: `Object`  
-Default: [`webpack-log`](https://github.com/webpack-contrib/webpack-log/blob/master/index.js)
-
-In the rare event that a user would like to provide a custom logging interface,
-this property allows the user to assign one. The module leverages
-[`webpack-log`](https://github.com/webpack-contrib/webpack-log#readme)
-for creating the [`loglevelnext`](https://github.com/shellscape/loglevelnext#readme)
-logging management by default. Any custom logger must adhere to the same
-exports for compatibility. Specifically, all custom loggers must have the
-following exported methods at a minimum:
-
-- `log.trace`
-- `log.debug`
-- `log.info`
-- `log.warn`
-- `log.error`
-
-Please see the documentation for `loglevel` for more information.
-
-### logLevel
-
-Type: `String`  
-Default: `'info'`
-
-This property defines the level of messages that the module will log. Valid levels
-include:
-
-- `trace`
-- `debug`
-- `info`
-- `warn`
-- `error`
-- `silent`
-
-Setting a log level means that all other levels below it will be visible in the
-console. Setting `logLevel: 'silent'` will hide all console output. The module
-leverages [`webpack-log`](https://github.com/webpack-contrib/webpack-log#readme)
-for logging management, and more information can be found on its page.
-
-### logTime
-
-Type: `Boolean`  
-Default: `false`
-
-If `true` the log output of the module will be prefixed by a timestamp in the
-`HH:mm:ss` format.
+If `false` (but not `undefined`), the server will not respond to requests to the root URL.
 
 ### mimeTypes
 
 Type: `Object`  
-Default: `null`
+Default: `undefined`
 
 This property allows a user to register custom mime types or extension mappings.
-eg. `mimeTypes: { 'text/html': [ 'phtml' ] }`.
+eg. `mimeTypes: { phtml: 'text/html' }`.
 
-By default node-mime will throw an error if you try to map a type to an extension
-that is already assigned to another type. Passing `force: true` will suppress this behavior
-(overriding any previous mapping).
-eg. `mimeTypes: { typeMap: { 'text/html': [ 'phtml' ] } }, force: true }`.
-
-Please see the documentation for
-[`node-mime`](https://github.com/broofa/node-mime#mimedefinetypemap-force--false) for more information.
+Please see the documentation for [`mime-types`](https://github.com/jshttp/mime-types) for more information.
 
 ### publicPath
 
-Type: `String`  
-_Required_
+Type: `String`
+Default: `output.publicPath` (from a configuration)
 
-The public path that the middleware is bound to. _Best Practice: use the same
-`publicPath` defined in your webpack config. For more information about
-`publicPath`, please see
-[the webpack documentation](https://webpack.js.org/guides/public-path)._
+The public path that the middleware is bound to.
 
-### reporter
+_Best Practice: use the same `publicPath` defined in your webpack config. For more information about `publicPath`, please see [the webpack documentation](https://webpack.js.org/guides/public-path)._
 
-Type: `Object`  
-Default: `undefined`
+### stats
 
-Allows users to provide a custom reporter to handle logging within the module.
-Please see the [default reporter](/lib/reporter.js)
-for an example.
+Type: `Boolean|String|Object`
+Default: `stats` (from a configuration)
+
+Stats options object or preset name.
 
 ### serverSideRender
 
 Type: `Boolean`  
 Default: `undefined`
 
-Instructs the module to enable or disable the server-side rendering mode. Please
-see [Server-Side Rendering](#server-side-rendering) for more information.
-
-### stats
-
-Type: `Object`  
-Default: `{ context: process.cwd() }`
-
-Options for formatting statistics displayed during and after compile. For more
-information and property details, please see the
-[webpack documentation](https://webpack.js.org/configuration/stats/#stats).
-
-### watchOptions
-
-Type: `Object`  
-Default: `{ aggregateTimeout: 200 }`
-
-The module accepts an `Object` containing options for file watching, which is
-passed directly to the compiler provided. For more information on watch options
-please see the [webpack documentation](https://webpack.js.org/configuration/watch/#watchoptions)
+Instructs the module to enable or disable the server-side rendering mode.
+Please see [Server-Side Rendering](#server-side-rendering) for more information.
 
 ### writeToDisk
 
 Type: `Boolean|Function`  
 Default: `false`
 
-If `true`, the option will instruct the module to write files to the configured
-location on disk as specified in your `webpack` config file. _Setting
-`writeToDisk: true` won't change the behavior of the `webpack-dev-middleware`,
-and bundle files accessed through the browser will still be served from memory._
-This option provides the same capabilities as the
-[`WriteFilePlugin`](https://github.com/gajus/write-file-webpack-plugin/pulls).

 Type: `Object`  
-Default: `MemoryFileSystem`
+Default: [memfs](https://github.com/streamich/memfs)
 
-Set the default file system which will be used by webpack as primary destination of generated files. Default is set to webpack's default file system: [memory-fs](https://github.com/webpack/memory-fs). This option isn't affected by the [writeToDisk](#writeToDisk) option.

+# 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;
+```
