Problem

I wish to provide my own Promise implementation (core-js), so I do not want browserify do bundle the es6-promise module. Is there a simple way to configure axios not to require this module? [code block]

Configure Axios to Use Custom Promise Implementation

Medium Risk

Axios internally uses the es6-promise library for Promise support. When using a custom Promise implementation like core-js, the es6-promise module may still be bundled by tools like Browserify, leading to conflicts or redundancy in the Promise implementation.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Install Axios and Core-js

    Ensure that both Axios and core-js are installed in your project. Core-js will provide the custom Promise implementation you want to use.

    bash
    npm install axios core-js
  2. 2

    Create a Custom Axios Instance

    Create a custom instance of Axios that uses your own Promise implementation. This can be done by setting the Promise implementation before importing Axios.

    typescript
    import { default as axios } from 'axios';
import { Promise } from 'core-js';
axios.defaults.Promise = Promise;
  3. 3

    Update Browserify Configuration

    Modify your Browserify configuration to exclude the es6-promise module from being bundled. This prevents conflicts with your custom Promise implementation.

    bash
    browserify -r axios -x es6-promise
  4. 4

    Test Your Axios Requests

    Make a few test API requests using your custom Axios instance to ensure that the requests are functioning correctly and that the custom Promise implementation is being utilized.

    typescript
    axios.get('https://api.example.com/data')
  .then(response => console.log(response.data))
  .catch(error => console.error(error));

Validation

Confirm the fix worked by running your application and checking for any errors related to Promise. Additionally, ensure that API requests are functioning as expected without any issues.
