How to download pdf using NodeJS and send it to a client?

Question

I am trying to download a PDF file using NodeJS and then send its data to the client so that it is embedded in the page. This is how I upload a PDF file:

exports.sendPdf = function(req, responce) { var donneRecu = req.body; var url = 'http://www.ieee.org/documents/ieeecopyrightform.pdf'//pdf link http.get(url, function(res) { var data = ''; res.on('data', function(chunk) { console.log('downloading'); data += chunk; }); res.on("end", function() { console.log('downloaded'); responce.header("Access-Control-Allow-Origin", "*"); responce.header("Access-Control-Allow-Headers", "X-Requested-With"); responce.header(200, {'content-type' : 'application/pdf'}); responce.send(data); }); }).on("error", function() { callback(null); }); } 

How to send data received from NodeJS on the client side?

EDIT I found a solution:

 exports.sendPdf = function(req, res) { var donneRecu = req.body; console.log(donneRecu['lien']); var url = donneRecu['lien']; //pdf link http.get(url, function(response) { var chunks = []; response.on('data', function(chunk) { console.log('downloading'); chunks.push(chunk); }); response.on("end", function() { console.log('downloaded'); var jsfile = new Buffer.concat(chunks).toString('base64'); console.log('converted to base64'); res.header("Access-Control-Allow-Origin", "*"); res.header("Access-Control-Allow-Headers", "X-Requested-With"); res.header('content-type', 'application/pdf'); res.send(jsfile); }); }).on("error", function() { callback(null); }); } 

next in my angular controller:

 var pdf = $scope.base64ToUint8Array(data); PDFJS.getDocument(pdf).then(functiongetPdfHelloWorld(_pdfDoc) { $scope.pdfDoc = _pdfDoc;$scope.renderPage($scope.pageNum); });

I also faced the same situation, and the code below helped me.

 var fs = require("fs"); var file = fs.createReadStream('./public/modules/datacollectors/output.pdf'); var stat = fs.statSync('./public/modules/datacollectors/output.pdf'); res.setHeader('Content-Length', stat.size); res.setHeader('Content-Type', 'application/pdf'); res.setHeader('Content-Disposition', 'attachment; filename=quote.pdf'); file.pipe(res); 

Hope this helps.
