Axios Interceptor to retry failed http calls
npm install axios-retry-interceptorConfigurable Axios Interceptor to retry failed http calls.
``
npm install --save axios-retry-interceptor
Import
`js`
import retryInterceptor from 'axios-retry-interceptor';
// or
const retryInterceptor = require('axios-retry-interceptor');
Set the interceptor for your axios instance. Voila! ✨
`js
retryInterceptor(axios, {
maxAttempts: 3,
waitTime: 1000
});
`
- axiosInstance - your axios instance
- options - config for retry interceptor
#### maxAttempts
Max number of times the interceptor should retry the failed http call.
_Type_: Number
_Default_: 3
_Example_: maxAttempts: 5
#### waitTime
Duration between each retry attempt in milliseconds(1s=1000ms).
_Type_: Number
_Default_: 0
_Example_: waitTime: 3000
#### errorCodes
Response errorCodes for which the interceptor should retry.
Ideally any implementation should retry only 5xx status(server errors) and should not retry 4xx status(client errors). The reason is, if a http call fails with a client error, then the retry call will have the same headers/params and will obviously fail. So by default all 5xx errors will be retried. If you want to customize the status for which the retries should be made, use this config.
_Type_: Array
_Default_: []
_Example_: errorCodes: [500, 501, 401]`
Ideally only idempotent http methods (GET, PUT, DELETE, HEAD, OPTIONS) should be retried on failed http calls. Non-idempotent methods like POST should NOT be retried and that's why this library will not permit retry of non-idempotent methods.
