# axios-retry
[![Build Status](https://travis-ci.org/softonic/axios-retry.svg?branch=master)](https://travis-ci.org/softonic/axios-retry)
Axios plugin that intercepts failed requests and retries them whenever possible.
## Installation
```bash
npm install axios-retry
```
### Note
Not working with `axios 0.19.0`. For details see the [bug](https://github.com/axios/axios/issues/2203). [`axios 0.19.1`](https://github.com/axios/axios/releases/tag/0.19.1) has fixed this bug.
## Usage
```js
// CommonJS
// const axiosRetry = require('axios-retry');
// ES6
import axiosRetry from 'axios-retry';
axiosRetry(axios, { retries: 3 });
axios.get('http://example.com/test') // The first request fails and the second returns 'ok'
.then(result => {
result.data; // 'ok'
});
// Exponential back-off retry delay between requests
axiosRetry(axios, { retryDelay: axiosRetry.exponentialDelay});
// Custom retry delay
axiosRetry(axios, { retryDelay: (retryCount) => {
return retryCount * 1000;
}});
// Works with custom axios instances
const client = axios.create({ baseURL: 'http://example.com' });
axiosRetry(client, { retries: 3 });
client.get('/test') // The first request fails and the second returns 'ok'
.then(result => {
result.data; // 'ok'
});
// Allows request-specific configuration
client
.get('/test', {
'axios-retry': {
retries: 0
}
})
.catch(error => { // The first request fails
error !== undefined
});
```
**Note:** Unless `shouldResetTimeout` is set, the plugin interprets the request timeout as a global value, so it is not used for each retry but for the whole request lifecycle.
## Options
| Name | Type | Default | Description |
| --- | --- | --- | --- |
| retries | `Number` | `3` | The number of times to retry before failing. |
| retryCondition | `Function` | `isNetworkOrIdempotentRequestError` | A callback to further control if a request should be retried. By default, it retries if it is a network error or a 5xx error on an idempotent request (GET, HEAD, OPTIONS, PUT or DELETE). |
| shouldResetTimeout | `Boolean` | false | Defines if the timeout should be reset between retries |
| retryDelay | `Function` | `function noDelay() { return 0; }` | A callback to further control the delay between retried requests. By default there is no delay between retries. Another option is exponentialDelay ([Exponential Backoff](https://developers.google.com/analytics/devguides/reporting/core/v3/errors#backoff)). The function is passed `retryCount` and `error`. |
