when reading data gives me following output. when append data <img src="data:image/jpeg;base64,(data)">, image doesn't show.

i tried :-

img.src = 'data:image/jpeg;base64,' + btoa(res); 

output rendered :-

<img src="data:image/jpeg;base64,w29iamvjdcbpymply3rd"> 

no image shown.

i use file stream demonstrate:

var rstream = fs.createreadstream('test.png');  var bufs = [];  rstream.on('data', function(chunk) {      bufs.push(chunk);  }).on('end', function() { // done      var fbuf = buffer.concat(bufs);      var base64 = (fbuf.tostring('base64'));      res.send('<img src="data:image/jpeg;base64,' + base64 + '">'); });
