I would like to be able to POST to my express app with a file URL and download that file to my own server.
For example, I display a list of images that are taken from a third-party and when the user clicks download, it will send a post request to this node app with the file URL (http://example.com/image.jpg) and download it to my server.
How would I do this? I apologize as I'm very new to node.
To download a remote file from node you could save what you would get from a http GET request to that file:
var http = require('http');
var fs = require('fs');//Handle files
var fileToDownload=req.body.fileToDownload;
var file = fs.createWriteStream("externalImage.jpg");
var request = http.get(fileToDownload, function(response) {
response.pipe(file);
});
Use the Formidable module to handle file uploads. It handles many tasks and features related to file upload.
npm install formidable@latest
