Example

Here is an example of how to use axios-token-refresh in your project:

import axios from 'axios';
import registerAxiosTokenRefresh from 'axios-token-refresh';

// Create an Axios instance
const apiClient = axios.create({
  baseURL: 'https://api.example.com',
});

// Define the refresh token function
const refreshAuthLogic = (failedRequest) =>
  axios.post('https://api.example.com/refresh-token', {
    token: localStorage.getItem('refreshToken'),
  }).then((tokenRefreshResponse) => {
    localStorage.setItem('accessToken', tokenRefreshResponse.data.accessToken);
    failedRequest.response.config.headers['Authorization'] = 'Bearer ' + tokenRefreshResponse.data.accessToken;
    return Promise.resolve(failedRequest);
  });

// Add the interceptor to the Axios instance
registerAxiosTokenRefresh(apiClient, { refreshRequest: refreshAuthLogic });

// Example API request
apiClient.get('/protected-resource', {
  headers: {
    Authorization: 'Bearer ' + localStorage.getItem('accessToken'),
  },
}).then((response) => {
  console.log('Protected resource data:', response.data);
}).catch((error) => {
  console.error('Error fetching protected resource:', error);
});

Configuration Options

Below is a table describing the available options for configuring token refresh behavior:

Option	Type	Description	Default
`refreshRequest`	`(error: any) => Promise<any>`	The function that will be called to refresh the token. It should return a promise.	Required
`statusCodes`	`number[]`	(Optional) List of status codes that should trigger a token refresh.	`[401]`
`shouldRetry`	`(error: AxiosError) => boolean`	(Optional) A custom function to determine whether to refresh. If provided, `statusCodes` will be ignored.	`undefined`
`retryTimes`	`number`	(Optional) The number of times to retry the request.	`1`
`onRetry`	`(requestConfig: AxiosRequestConfig) => AxiosRequestConfig \| Promise<AxiosRequestConfig>`	(Optional) A callback function that is called before each `refreshRequest`. It can modify and return the request configuration.	`undefined`
