Although they serve the same purpose, there are some differences between them.
- API: Fetch is a browser API that comes with modern browsers and is used for making HTTP requests. On the other hand, Axios is a third-party library that can be used both in the browser and Node.js environments.
- Syntax: The syntax for making HTTP requests with Fetch and Axios is different. With Fetch, you use the built-in fetch() function, whereas, with Axios, you need to create an instance of the Axios library and use its methods to make requests.
- Browser Support: Fetch is built into most modern web browsers, including Chrome, Firefox, and Safari. Axios, on the other hand, is a third-party library that needs to be included in your project. This means that Axios can be used in a wider range of browsers, including older versions.
- Error Handling: Error handling is slightly different between the two libraries. Fetch returns a promise that only rejects on network errors, whereas Axios can be configured to reject on HTTP errors as well.
- Interceptors: Axios allows you to use interceptors to modify requests or responses before they are sent or received. This can be useful for adding headers, handling authentication, or transforming data. Fetch does not have built-in interceptors.
- File uploads: Axios provides a convenient way to upload files using the FormData object. This feature is not available in Fetch.
