How to fetch msg body using node-imap module - node.js

Question

I'm using node-imap npm module to fetch the email and i'm getting pretty everything but the content of msg.
I used an already provided example on their git, shown below
openInbox(function(err, box) {
if (err) throw err;
var f = imap.seq.fetch(box.messages.total + ':*', { bodies: ['HEADER.FIELDS (FROM)','TEXT'] });
f.on('message', function(msg, seqno) {
console.log('Message #%d', seqno);
var prefix = '(#' + seqno + ') ';
msg.on('body', function(stream, info) {
if (info.which === 'TEXT')
console.log(prefix + 'Body [%s] found, %d total bytes', inspect(info.which), info.size);
var buffer = '', count = 0;
stream.on('data', function(chunk) {
count += chunk.length;
buffer += chunk.toString('utf8');
console.log('BUFFER', buffer) //HEre i am able to view the body
if (info.which === 'TEXT')
console.log(prefix + 'Body [%s] (%d/%d)', inspect(info.which), count, info.size);
});
stream.once('end', function() {
if (info.which !== 'TEXT')
console.log(prefix + 'Parsed header: %s', inspect(Imap.parseHeader(buffer)));
else
console.log(prefix + 'Body [%s] Finished', inspect(info.which));
});
});
msg.once('attributes', function(attrs) {
console.log(prefix + 'Attributes: %s', inspect(attrs, false, 8));
});
msg.once('end', function() {
console.log(prefix + 'Finished');
});
});
f.once('error', function(err) {
console.log('Fetch error: ' + err);
});
f.once('end', function() {
console.log('Done fetching all messages!');
imap.end();
});
});
In this example i am able to console out the content of the msg but i am unable to return it as json.

The returned value is a buffer. If you want a string, you can call the toString() method on the buffer. You said you want JSON. If the email body is properly formatted JSON you could also decode it:
var json = JSON.parse(buffer.ToString());
