Axios

What is Axios?

A popular, promise-based HTTP client for JavaScript and Node.js that makes it easy to send asynchronous HTTP requests to REST endpoints and perform CRUD operations. Features automatic JSON data transformation, request and response interceptors, request cancellation, timeout handling, and built-in protection against XSRF. Works in both browsers and Node.js environments. One of the most widely used HTTP clients in the JavaScript ecosystem. Known for its simple API, excellent TypeScript support, and comprehensive feature set.

When to use it

• Perfect for making HTTP requests in React, Vue, Angular, and Node.js applications.
• Ideal when you need a reliable, feature-rich alternative to the native fetch API.
• Excellent for API integration, handling authentication tokens, request/response transformation, and error handling.
• Commonly used in frontend applications for consuming REST APIs, in backend services for making external API calls, and when you need request interceptors or automatic request/response transformation.

When NOT to use it

• When you want to avoid external dependencies - native fetch API is built-in
• Very simple requests - fetch API might be sufficient
• When bundle size is critical - fetch has zero bundle size
• Modern browsers only - fetch is widely supported now
