axios-better-stacktrace

Axios plugin that provides better stack traces for axios errors.

Check this axios issue for more details.


Installation

NPM
``bash
npm install axios-better-stacktrace
`

Yarn
`bash
yarn add axios-better-stacktrace
`

$3

It was tested with axios 0.21.0.

Usage

`js
// CommonJS
// const axiosBetterStacktrace = require('axios-better-stacktrace').default;

// ES6
import axiosBetterStacktrace from 'axios-better-stacktrace';

// use it before any other interceptors
axiosBetterStacktrace(axiosAgent);

// when using promises response error will get an enhanced stack trace automatically
axiosAgent.get('https://npmjs.com//').catch(enhancedError => console.error(enhancedError));

// or using async/await
(async () => {
try {
await axiosAgent.get('https://npmjs.com//');
} catch (enhancedError) {
console.error(enhancedError);
}
})();

// or using a response interceptor and an error callback (e.g. could be useful with a logging middleware)
axiosAgent.interceptors.response.use(response => response, enhancedError => {
console.error(enhancedError);

return result;
});

// you can restore original agent behavior if needed
const restoreAgent = axiosBetterStacktrace(axiosAgent);

// some code here...

restoreAgent && restoreAgent();
`
