Node.JS - Encoding images in base64 using Buffer

json node.js base64

fs.readFile(attachment, function(err, data) {   var base64data = new Buffer(data).toString('base64');   [your API call here]});

It takes some time until the results are there, so by the time you've got the data, the outer scopes execution is already over.

json node.js base64

Just specify "base64" as the encoding. Per the docs:

If no encoding is specified, then the raw buffer is returned.

fs.readFile(attachment, {encoding: 'base64'}, function(err, base64data) {   [your API call here]});
