Node fetch3/5/2023 ![]() The request module was the most often used technique for sending HTTP requests in Node for a very long time before the Fetch API was introduced. It was mentioned in a question response on Hacker News by one of Node's main contributors that the browser's Fetch API implementation depends on a browser-based Web Streams API and the AbortController interface (for aborting fetch requests), both of which were not previously included in Node.js.Īs a result, choosing the appropriate method to include it in the core of Node.js proved to be challenging. Although the Fetch API has been around for some time, it hasn't been incorporated into the core of Node.js because of several limitations. The fact that Fetch uses promises to create a clearer, cleaner API while avoiding callback hell is a key benefit it has over XMLHttpRequest. The Fetch API, which was introduced in 2015 as a more contemporary replacement for XMLHttpRequest, has since taken over as the de facto standard for asynchronous call-making in web applications. As a result, JavaScript frameworks, most notably jQuery, had to abstract it to make implementation and success/error handling more streamlined. Support for other data formats, principally JSON, HTML, and plaintext, was added after it was initially released.īack then, the XMLHttpRequest API functioned well, but it became increasingly challenging to use as the web expanded. XMLHttpRequest was first intended to get XML data over HTTP, hence the name. ![]() In 1998, Internet Explorer 5 introduced XMLHttpRequest, an API designed to get around this limitation.
