Piping remote file in ExpressJS

Question

I would like to read a remote image and display it. I can save the file but not getting the code right to display it. Ideally I just want to pass the file right though without processing - not sure if a tmp file step is required or not. This code displays nothing - no errors. I tried res.pipe(response) as well.

var url = 'http://proxy.boxresizer.com/convert?resize=50x50&source=' + filename  var request = http.get(url, function(response) {    var tmp = path.join(require('os').tmpDir(), filename);    var outstream = require('fs').createWriteStream(tmp);    response.pipe(outstream);   response.on('end', function() {     res.set('Content-Type', 'image/jpg');       res.pipe(outstream);       res.end();   }); });

Well I'd still like to know how to make the above work but I solved my issue in one line with the request module!

var url = 'http://proxy.boxresizer.com/convert?resize=50x50&source=' + filename require('request').get(url).pipe(res);  // res being Express response

Since request is deprecated, you can alternatively use node-fetch like so:

app.get("/", (req, res) => {     fetch(actualUrl).then(actual => {         actual.headers.forEach((v, n) => res.setHeader(n, v));         actual.body.pipe(res);     }); });
