Axios vs Fetch API: Which is Better for Performance?

What are the performance differences between Axios and Fetch API?

Axios and Fetch API both serve to make HTTP requests, but they have different performance characteristics. Axios is built on top of the XMLHttpRequest and has built-in features like interceptors and automatic JSON data transformation, which can enhance performance in certain scenarios. Fetch, on the other hand, is a modern API that returns Promises and is generally more lightweight, but it lacks some of the advanced features of Axios.

In what situations would one be better than the other?

If you need advanced features like request cancellation, interceptors, or automatic JSON parsing, Axios might be the better choice. However, if you want a lightweight solution and are working with modern browsers, Fetch API could be more suitable.

How do they compare in terms of error handling?

Axios automatically rejects the Promise for HTTP error statuses (like 404 or 500), making error handling straightforward. Fetch, however, does not reject the Promise on HTTP error statuses, so you need to check the response status manually.

Which one is more widely used in the industry?

Axios tends to be more popular in the industry due to its rich feature set and ease of use, especially in larger applications. However, Fetch is gaining traction as a native solution in modern web development.
