Difference between Axios and Fetch API

In this article, we will discuss the difference between Axios and Fetch API. Before discussing their difference, we must know about the Axios and Fetch API.

What is the Axios?

The popular third-party module Axios allows JavaScript users to make HTTP requests more easily. It is strongly recommended in the React.js, Vue.js, and Node.js communities. Its notable attributes include:

• Promise-Based: In its being promise-based, it also offers a similar ease of handling asynchronous operations like Fetch.
• Axios automatically transforms JSON data; hence, there is no need for extra parsing and it eases working with requests and responses from APIs.
• Simpler Syntax: When using Axios, we do not have to write a lot of boilerplate code for common tasks. For example, handling timeouts, converting requests/responses, setting headers, etc.
• Cancellation request: We can use the functionality of Axios CancelToken to cancel a request. It might clean up our application.
• Interceptors: Axios provides better interceptors for adding in any middleware like this. We can set up some standard configurations such as our authentication tokens.

Syntax:

It has the following syntax:

What is the Fetch API?

The Fetch API is a modern JavaScript replacement for sending XMLHTTP requests. It replaced XMLHttpRequest in ES6. However, it is less opinionated and has a stronger feature set. When comparing it with the Fetch API, the following is very important:

• Based on Promises: As fetch works on promises, developers can work much more easily with asynchronous programming and can resolve requests because there are in-built promises.then() and catch().
• Modern Syntax: Fetch is the way modern code handles easy reading and writing.
• Built into the Browser: No other installs or imports are needed with this nice little built-in API.
• Streaming: It gives fetch the ability to stream so that developers can work with large datasets incrementally, allowing them to process part of the response while they wait on the rest.

Syntax:

It has the following syntax:

Key differences between Axios and Fetch API:

There are several key differences between Axios and Fetch API. Some of the main differences are as follows:

Conclusion:

In conclusion, Axios and the Fetch API are good ways to go when it comes to making HTTP requests with JavaScript, and both have their own advantages. Axios is best suited for those high-level applications because of its richer experience, automatic JSON data transformation, request cancellation, and easier syntax for passing arguments to requests. Otherwise, we can perform with native browser support, stream large amounts of data, and directly work with promises using the lightweight modern Fetch API. Both will be suitable options depending on which best fits the bill for a particular project's needs. If we prefer a more direct and native solution, then going in with the Fetch API would be a decent option. Otherwise, if we need more advanced features and cleaner codebases, Axios would do the trick.
