📌 What is Axios?
Introduction to React Axios
Axios is a popular HTTP client library that makes it easier to fetch data from external APIs in React. It is promise-based, lightweight, and works with both browsers and Node.js. Axios simplifies handling requests, responses, errors, and supports features like request/response interception and automatic JSON transformation.
📌 Pre-Requisites
- React Fundamentals
- Components
- useState & useEffect
- Arrow Functions & Destructuring
- Promise, Async & Await
- Fetch API basics
⚙️ Why Use Axios in React?
- Good defaults for JSON data (no manual headers or conversions needed)
- Supports all HTTP methods with simple function names (.get, .post, etc.)
- Simpler syntax than Fetch API
- Better error handling (throws 400 & 500 range errors automatically)
- Can be used in both client (browser) and server (Node.js)
🚀 Setting up Axios in React
To use Axios in React, you need:
- An existing React project
