Axios vs Fetch: Choosing an HTTP Client for React

Axias vs Fetch: Choosing an HTTP Client for React

Axios and fetch are the two main HTTP clients for React. Here is how they compare and how to choose.

fetch

fetch is built into the browser, no library needed. It needs manual JSON parsing and error handling, since it does not throw on non-2xx responses.

axios

axios is a library with automatic JSON parsing, interceptors for auth and error handling, request and response transforms, and cleaner error handling. It throws on non-2xx responses, which is usually what you want.

When to Use fetch

When you want no extra dependency and are fine with manual setup. For simple apps or one-off calls, fetch is enough.

When to Use axios

When you want interceptors for auth tokens, automatic JSON parsing, transforms, and clean error handling. For an app with many API calls and auth, axios saves a lot of boilerplate.

The Trade-off

fetch: no dependency, more manual work. axios: a dependency, less manual work and cleaner code for many calls. Both work; the choice is about convenience and dependency tolerance.

Interceptors Are the Big Difference

For most teams, axios's interceptors are the deciding factor. Adding the auth token to every request in one place, and handling errors globally, is a big win as the app grows.

The Takeaway

Use fetch for no-dependency simplicity, or axios for interceptors, automatic JSON parsing, and cleaner error handling. For apps with auth and many API calls, axios's interceptors are usually the deciding factor.
