axios-cancel

Simplify cancellation of http requests when using the awesome axios library

Installation

Using npm:

npm install axios-cancel --save

Getting started

axios-cancel simplifies the interface of the Cancel api introducted in axios v1.5, which is based on the cancelable promises proposal

import axios from 'axios';
import axiosCancel from 'axios-cancel';

axiosCancel(axios, {
  debug: false // default
});

...

// Single request cancellation
const requestId = 'my_sample_request';
const promise = axios.get(url, {
  requestId: requestId
})
  .then((res) => {
    console.log('resolved');
  }).catch((thrown) => {
    if (axios.isCancel(thrown)) {
      console.log('request cancelled');
    } else {
      console.log('some other reason');
    }
  });

axios.cancel(requestId);
// aborts the HTTP request and logs `request cancelled`

Examples

Multiple subsequent requests with same requestId

...

const requestId = 'my_sample_request';
const promise1 = axios.get(url, {
  requestId: requestId
})
  .then((res) => {
    console.log('resolved promise 1');
  }).catch((thrown) => {
    if (axios.isCancel(thrown)) {
      console.log('request 1 cancelled');
    } else {
      console.log('some other reason');
    }
  });

// another request with same `requestId`, before `promise1` resolution
const promise2 = axios.get(url, {
  requestId: requestId
})
  .then((res) => {
    console.log('resolved promise 2');
  }).catch((thrown) => {
    if (axios.isCancel(thrown)) {
      console.log('request 2 cancelled');
    } else {
      console.log('some other reason');
    }
  });

// aborts the first HTTP request, and cancels the first promise 
// logs `request 1 cancelled`
// logs `resolved promise 2`

Multiple requests with different requestId, cancell all

...

const requestId1 = 'my_sample_request_1';
const promise1 = axios.get(url, {
  requestId: requestId1
})
  .then((res) => {
    console.log('resolved promise 1');
  }).catch((thrown) => {
    if (axios.isCancel(thrown)) {
      console.log('request 1 cancelled');
    } else {
      console.log('some other reason');
    }
  });

const requestId2 = 'my_sample_request_2';
const promise2 = axios.get(url, {
  requestId: requestId2
})
  .then((res) => {
    console.log('resolved promise 1');
  }).catch((thrown) => {
    if (axios.isCancel(thrown)) {
      console.log('request 2 cancelled');
    } else {
      console.log('some other reason');
    }
  });

axios.cancelAll();

// aborts all HTTP request, and cancels all promises
// logs `request 1 cancelled`
// logs `request 2 cancelled`
