Here’s a sample function to download an image: 'use strict'Ĭonst path = Path.resolve(_dirname, 'images', 'code.jpg')Ĭonst writer = Fs. 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.įrom 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 Let’s implement the actual download functionality. It’s for illustration purposes and an image is visually appealing because you can look at it when opening the file on your hard disc.Īlright, you have a sample image and the related download URL.
