Notes
A couple more notes to round it off
Semver
Until axios reaches a 1.0 release, breaking changes will be released with a new minor version. For example 0.5.1, and 0.5.4 will have the same API, but 0.6.0 will have breaking changes.
Promises
axios depends on a native ES6 Promise implementation to be supported. If your environment doesn't support ES6 Promises, you can polyfill.
TypeScript
axios includes TypeScript definitions.
import axios from 'axios';
axios.get('/user?ID=12345');
Resources
Credits
axios is heavily inspired by the $http service provided in Angular. Ultimately axios is an effort to provide a standalone $http-like service for use outside of Angular.
