I'd like to fetch mail from a mailbox regularly using a Node daemon. The call to the connection method is made in app.js
.
The javascript file I use to connect to my mailbox ( mail.js
):
var imap = new Imap({
user: 'xxxx@hotmail.com',
password: config.get.gmail_password,
host: 'xxxxx',
port: 993,
tls: true
});
var fetchMail = function()
{
console.log('Connection');
imap.connect();
};
//fetchMail();
imap.once('ready', function() {
console.log('Ready');
imap.search([ 'UNSEEN', ['FROM', 'xxxx'] ], function(err, results)
{
// Do Stuff
}
exports.fetchMail = fetchMail;
If I use fetchMail()
directly from mail.js
, everything is fine.
However, when I try to call it from app.js
:
var mail = require('./js/mail');
mail.fetchMail()
Then, the method stay in the fetchMail()
function from mail.js
and the imap.once('ready', function())
is never triggered.
I guess it is a scope issue with the imap
var in mail.js
.
How can I fix this?
EDIT
I solved this in a way I don't like. I wrote everything's related to the imap var inside the fecthMail()
function.
Please, do not hesitate to write a more efficient answer to this.
You would need to bind the event every time you connect. So like so:
var fetchMail = function()
{
console.log('Connection');
imap.once('ready', function() {
console.log('Ready');
imap.search([ 'UNSEEN', ['FROM', 'xxxx'] ], function(err, results)
{
// Do Stuff
}
}
imap.connect();
};
The approach and idea is great. All you need is to change the syntax of mail.js file to return a module. In another words when you do
var mail = require('./js/mail');
what do you expect to be in the mail variable?
You might need to change logic around, but try this:
var MailHandler = function () {}
var imap = new Imap({
user: 'xxxx@hotmail.com',
password: config.get.gmail_password,
host: 'xxxxx',
port: 993,
tls: true
});
MailHandler.init = function(){
imap.once('ready', function() {
console.log('Ready');
imap.search([ 'UNSEEN', ['FROM', 'xxxx'] ], function(err, results)
{
// Do Stuff
}
}
}
MailHandler.fetchMail = function()
{
console.log('Connection');
imap.connect();
};
//fetchMail();
module.exports = new MailHandler()
