All methods specified in the Fetch Standard are implemented. This class allows manipulating and iterating over a set of HTTP headers. node-fetch only supports 'default' and 'error' and does not make use of filtered responses. response.typeД¬onvenience property representing the response's type. Will evaluate to true if the internal redirect counter is greater than 0. response.redirectedД¬onvenience property representing if the request has been redirected at least once. Will evaluate to true if the response status was greater than or equal to 200 but smaller than 300. response.okД¬onvenience property representing if the request ended normally. The constructor is identical to that in the browser.Д«ecause Node.js does not implement service workers (for which this class was designed), one rarely has to construct a Response directly.

options A ResponseInit options dictionaryД¬onstructs a new Response object.

The following properties are not implemented in node-fetch at this moment: This class implements the Body interface. In most cases, directly fetch(url, options) is simpler than creating a Request object.ДЄn HTTP(S) response. The constructor is identical to that in the browser.

options Options for the HTTP(S) requestД¬onstructs a new Request object.

input A string representing a URL, or another Request (which will be cloned).

See options for exact meaning of these extensions. The following node-fetch extension properties are provided: This class implements the Body interface.Дue to the nature of Node.js, the following properties are not implemented at this moment: Import fetch from 'node-fetch' class HTTPResponseError extends Error ДЄn HTTP(S) request containing information about URL, method, headers, and the body. Note: when body is a Stream, Content-Length is not set automatically.

If you happen to use a missing feature that window.fetch offers, feel free to open an issue.Д¬urrent 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).

For example, an MP4 file can be downloaded using node-fetch.

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. To download a file using Node.js, use one of the the many npm request libraries. HereвЂ™s a sample function to download an image: 'use strict'Д¬onst path = Path.resolve(_dirname, 'images', 'code.jpg')Д¬onst writer = Fs.A light-weight module that brings Fetch API to Node.js.Д¬onsider supporting us on our Open Collective: This will pass the incoming bytes from your read-stream to the write-stream and ultimately flush every piece of the image to a local file. This tells Axios to provide the response.data as a readable stream.ДЇrom there, pipe the read-stream into a Node.js write-stream that points to a file on your local disc. To download a file, explicitly define responseType: 'stream' as a request option. The Axios initialization to request a file is equal to a request that expects another response payload format, like JSON. Implement the Axios File Download in Node.js LetвЂ™s implement the actual download functionality. ItвЂ™s for illustration purposes and an image is visually appealing because you can look at it when opening the file on your hard disc.ДЄlright, you have a sample image and the related download URL. The image example doesnвЂ™t mean you canвЂ™t download other file formats.

You can access this image without restriction and even download it without registration. To illustrate the actual download implementation in Axios, letвЂ™s use the following вЂњcodingвЂќ picture from Markus Spiske which is publicly available on Unsplash. You need an accessible Internet URL linking to the resource to download a file. The streaming option isnвЂ™t supported in Axios when using the library in the browser. This tutorial is specifically for Node.js, because youвЂ™ll stream the image to a file on the disc.
