is there any way to convert byte array to blob object on client side in node.js

Question

Is there any way to get blob object from byte array client side without actual downloading file

Client side where I want to pass blob object =>

request.get('/api/get/video/blob/'+d1+'/'+d2+'/'+d3) .end((err, res) => { if (err) { console.log("err="+err) } else { console.log("data="+res) if(res) { var uploadVideo = new UploadVideo(); uploadVideo.uploadFile(access_token,res// need actual blob object to pass @ res); but what I get is byte array see following code

Server side=>

server.route({ method: 'GET', path: '/api/get/video/blob/{d}/{s}/{x}', handler: function handler(request, reply) { const {d,s,x} = request.params; const key = d+'/'+s+'/'+x; var bucket = 're.render-previews'; var params = { Bucket: bucket, Key: key }; s3.getObject(params, function(err, data) { console.log("coming back"); if (err) { console.log("err=>"); console.log(err); // reject(err) } else { console.log("data=>"); console.log(data); reply(data); // where I get byteArray } }); } });

in web development client side is the stuff that runs in the browser. programmers.stackexchange.com/questions/171203/… . so i guess you are meaning server side. Can you show us some code? — Roland Starke

this line of code worked for me var blob = new Blob([new Uint8Array(BYTEARRAY)], { type: 'video/mp4' });

This works for me.

var blob = new Blob([new Uint8Array(BYTEARRAY).buffer], { type: 'video/mp4' });
