node-imap + Mailparser not showing complete email list
I am having problems pushing the parsed email into the array. for example in the email server i have a total of 2 email for this date. after pushing the email inside the mailparser it only shows 1 email instead of 2. I confirmed the total email in result.length. here is my sample code.
var imap = new Imap({
user: retAccount.email_account,
password: atob(retAccount.email_password),
host: retAccount.imap_host,
port: retAccount.imap_port,
tls: ssl
});
function openInbox(cb) {
imap.openBox(retFolder, false, cb);
}
imap.once('ready', function() {
openInbox(function(err, box) {
if (err) throw err;
imap.search(['ALL',['SINCE', '2019-08-05'], ['BEFORE', '2019-08-06']], function (err, results) {
var f = imap.fetch(results, {
bodies: '',
struct: true
});
var messageInbox = [];
var objMessage = {};
f.on('message', function(msg, seqno) {
//console.log('Message #%d', seqno);
var prefix = '(#' + seqno + ') ';
msg.on('body', function(stream, info) {
async function main(stream,info,results) {
let parsed = await simpleParser(stream);
var attachment = '0';
if(parsed.attachments.length != 0){
attachment = '1';
}
objMessage = {
seq:info.seqno.toString(),
id:parsed.messageId,
subject: parsed.subject,
date:dateFormat(parsed.date,'yyyy-mm-dd HH:MM:ss'),
from_email:parsed.from.value[0].address,
from_name:parsed.from.value[0].name,
attachment:attachment,
};
//console.log(objMessage);
messageInbox.push(objMessage);
}
main(stream,info,results);
});
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() {
jsonRes = {
success: '1',
result: {
account_list:[],
email_object: messageInbox
},
successMessage: 'Email List',
errorMessage: errorMessage
};
res.status(201).json(jsonRes);
res.end();
imap.end();
//console.log('Done fetching all messages!');
imap.end();
});
});
});
});
imap.once('error', function(err) {
console.log(err);
});
imap.once('end', function() {
console.log('Connection ended');
});
imap.connect();
Is your 'message'
(or more specifically the 'body'
) event handler called twice? If so, then perhaps it's a bug/issue with mailparser
.
Hello! thank you for replying. I only call the event once. for example i have 4 emails it will only push 3 emails, but if I console log the parsed data inside the mailparser it will show 4 emails. maybe i am having problems inside the mailparser when im pushing the data into the array. is there anything i can do to fix the problem? :(
I think i got it fixed buy putting set interval "delay" inside the f.once('end) before i throw the result . =)
Scenario: This is a wild guess considering the fact that I am also experiencing something similar very to this.
MailParsers
function called here is asynchronous and obviously takes a while before it's done parsing. While it's parsing the data, the f.once("end", ()=> {});
would most likely have been emitted meaning we probably have no access to whatever was returned in the mailParser
if we end everything on f.once("end", () =>{}
).
I assume there might be much better ways to handle this but setTimeout
seems to be a fair workaround at this point IMO.
