The Fetch API is finally stable in Node.js

The stabilization of the Fetch API in Node.js, achieved in version 21, marks a significant advancement for developers by providing a modern, standardized method for performing HTTP requests across both browser and server environments. The Fetch API, introduced as a successor to the XMLHttpRequest API, leverages promises for a cleaner and more efficient way of handling asynchronous calls. Initially facing integration challenges due to its reliance on browser-specific features, Fetch's stabilization in Node.js was facilitated by the development of the high-performance HTTP client library, Undici. This integration eliminates the need for external libraries like node-fetch and enhances performance and compatibility with modern JavaScript patterns such as async/await. Despite its benefits, such as improved cross-platform familiarity and faster implementation, the Fetch API in Node.js also presents challenges including lack of built-in progress events, limited support for older Node.js versions, and complexities in cookie management. Developers are advised to upgrade their Node.js versions and migrate from external libraries to fully utilize the native Fetch API, while also being prepared to handle common issues like network errors, CORS restrictions, and request timeouts.
