Learn how to use the Fetch API in Node.js, Deno, and Bun. Fetch API is a native alternative to XMLHttpRequest for making HTTP requests in browsers and server-side code. The API is identical across platforms, but there are some restrictions when making client-side fetch requests. You can manipulate and examine HTTP headers in the request and response using a Headers object. Fetch requests can be customized using options such as method, headers, and credentials. The fetch() promise resolves even if the server returns a 404 error. Aborting fetch requests can be done using an AbortController or AbortSignal. Making fetch requests in series may not be efficient, consider using Promise.allSettled() for concurrent requests.
