Axios
js, widely used for making API requests with a simpler, more consistent API than the native fetch function.
Definition
Axios is a promise-based HTTP client for JavaScript that works in both browsers and Node.js, widely used for making API requests with a simpler, more consistent API than the native fetch function.
Overview
Axios provides automatic JSON transformation, request and response interceptors, client-side protection against XSRF, and the ability to cancel in-flight requests, making it one of the most widely downloaded packages in the JavaScript ecosystem. It's commonly used in React and Vue.js frontends to call REST APIs, and in Node.js backends — often built with Express.js — to call other services. Axios works well with TypeScript thanks to typed request and response generics, and is a common early tool taught alongside API-calling basics, as in the project Learn Node.js Through Building a Music API.
