Difference between Fetch and Axios for making http requests



Fetch or Axios are frequently used by developers to perform smooth HTTP protocol communication between web applications and servers. While they are similar, some people think Axios is more straightforward. But there's also the built-in API Fetch, which is just as capable as Axios.

Fetch API

The Fetch API is a built-in JavaScript function that provides a simple interface for making HTTP requests. Introduced in modern browsers, it is a native alternative to older methods like XMLHttpRequest.

Syntax

fetch(url, options)
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error('Error:', error));

Fetch returns a promise, which makes it suitable for handling asynchronous operations. The API is flexible but can be verbose for complex scenarios like error handling and interceptors.

Axios

Axios is a popular third-party library for making HTTP requests in JavaScript. It is often favored for its simplicity and ease of use, particularly in larger applications where additional features like interceptors and request/response transformation are beneficial.

Syntax

axios.get(url)
  .then(response => console.log(response.data))
  .catch(error => console.error('Error:', error));

Axios also returns a promise and offers a more concise syntax with built-in support for features like automatic JSON parsing and timeout management.

Differences Between Fetch and Axios

Feature Fetch API Axios
Native Support Built into modern browsers; no need for additional libraries. Requires installation via npm or CDN.
Syntax Can be verbose, especially with error handling. More concise and straightforward.
Error Handling Must check manually for HTTP errors (e.g., 404, 500). Automatically handles HTTP errors.
Request Configuration Options object for configuring headers, method, body, etc. Axios config object supports headers, params, timeout, and more.
Browser Support Widely supported, but some older browsers may require polyfills. Also widely supported, with better backward compatibility.
Interceptors No built-in support for request/response interceptors. Built-in support for interceptors, useful for authentication and logging.
Cancellation of Requests Requires additional logic with AbortController. Built-in support for request cancellation using CancelToken.
