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. The image example doesn’t mean you can’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, let’s use the following “coding” 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 isn’t supported in Axios when using the library in the browser. This tutorial is specifically for Node.js, because you’ll stream the image to a file on the disc.
