Difference between Fetch and Axios in React JS

Fetch vs. Axios in React JS

Fetch and Axios are both popular HTTP client libraries used in React JS to make network requests. While they share the same core functionality of sending requests and handling responses, there are some key differences between them.

Fetch API

• Native to JavaScript: The Fetch API is built into modern browsers, making it a native solution without requiring additional dependencies.
• Promises-based: Fetch returns a Promise, making it easy to work with asynchronous operations.
• Simpler syntax: Fetch has a relatively straightforward syntax, making it easier to learn for beginners.
• Limited features: While Fetch provides basic functionality for making requests and handling responses, it lacks some advanced features found in libraries like Axios.

Axios

• Third-party library: Axios is a third-party library that needs to be installed using a package manager like npm or yarn.
• Promise-based: Axios also returns Promises, making it compatible with asynchronous workflows.
• Rich feature set: Axios offers a wider range of features, including:

Interceptors: Intercept requests and responses for global transformations or error handling.

Automatic JSON parsing: Automatically parses JSON responses.

Cancellation tokens: Cancel requests in progress.

Custom headers: Set custom headers for requests.

Progress tracking: Track the progress of large file uploads and downloads.

Timeout handling: Set timeouts for requests.

When to Use Which

• Fetch:

If you prefer a native solution without external dependencies.

For simple, straightforward requests.

• Axios:

If you need advanced features like interceptors, automatic JSON parsing, or cancellation tokens.

If you're working with a large or complex application.

In summary, both Fetch and Axios are valid options for making HTTP requests in React JS. The choice between them often depends on your specific requirements and preferences. For most use cases, Axios provides a more robust and feature-rich solution, but Fetch can be a good choice for simple applications or if you prefer a native approach.
