Read email body with node js imap - node.js

Question

I'm trying to read the body of an e-mail that is retrieved with node js. I'm using this npm module: https://github.com/mscdex/node-imap
And I can get pretty much all the information of the email, except reading the content of the body.
Any ideas?
Thanks,

You can use this code to fetch email body and mark it as seen
var Imap = require("imap");
var MailParser = require("mailparser").MailParser;
var Promise = require("bluebird");
Promise.longStackTraces();
var imapConfig = {
user: 'USERNAME',
password: 'PASSWORD',
host: 'HOST',
port: 993,
tls: true
};
var imap = new Imap(imapConfig);
Promise.promisifyAll(imap);
imap.once("ready", execute);
imap.once("error", function(err) {
log.error("Connection error: " + err.stack);
});
imap.connect();
function execute() {
imap.openBox("INBOX", false, function(err, mailBox) {
if (err) {
console.error(err);
return;
}
imap.search(["UNSEEN"], function(err, results) {
if(!results || !results.length){console.log("No unread mails");imap.end();return;}
/* mark as seen
imap.setFlags(results, ['\\Seen'], function(err) {
if (!err) {
console.log("marked as read");
} else {
console.log(JSON.stringify(err, null, 2));
}
});*/
var f = imap.fetch(results, { bodies: "" });
f.on("message", processMessage);
f.once("error", function(err) {
return Promise.reject(err);
});
f.once("end", function() {
console.log("Done fetching all unseen messages.");
imap.end();
});
});
});
}
function processMessage(msg, seqno) {
console.log("Processing msg #" + seqno);
// console.log(msg);
var parser = new MailParser();
parser.on("headers", function(headers) {
console.log("Header: " + JSON.stringify(headers));
});
parser.on('data', data => {
if (data.type === 'text') {
console.log(seqno);
console.log(data.text); /* data.html*/
}
// if (data.type === 'attachment') {
// console.log(data.filename);
// data.content.pipe(process.stdout);
// // data.content.on('end', () => data.release());
// }
});
msg.on("body", function(stream) {
stream.on("data", function(chunk) {
parser.write(chunk.toString("utf8"));
});
});
msg.once("end", function() {
// console.log("Finished msg #" + seqno);
parser.end();
});
}
hope this code will help you :)

The Body of the message is in the spot where i have console.log("BUFFER", buffer)
I'm using node-imap npm module
imap.once('ready', function() {
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)
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();
});
});
});

Try:
msg.once('end', function() {
console.log(buffer);
});
