If you happen to use a missing feature that window.fetch offers, feel free to open an issue.Ĭurrent stable release ( 3.x) requires at least Node.js 12.20.0.Useful extensions such as redirect limit, response size limit, explicit errors for troubleshooting.Decode content encoding (gzip/deflate/brotli) properly, and convert string output (such as res.text() and res.json()) to UTF-8 automatically.Use native Node streams for body, on both request and response.Use native promise and async functions.Make conscious trade-off when following WHATWG fetch spec and stream spec implementation details, document known differences.See Jason Miller's isomorphic-unfetch or Leonardo Quixada's cross-fetch for isomorphic usage (exports node-fetch for server-side, whatwg-fetch for client-side).
JAVASCRIPT FETCH CODE
Instead of implementing XMLHttpRequest in Node.js to run browser-specific Fetch polyfill, why not go from native http to fetch API directly? Hence, node-fetch, minimal code for a window.fetch compatible API on Node.js runtime. A light-weight module that brings Fetch API to Node.js.Ĭonsider supporting us on our Open Collective: In JavaScript, the fetch() method is used to make asynchronous requests to the server and load the information that is returned by the server onto the web.
