mail-watcher

mail-watcher

Notify your nodejs scripts of incoming imap mail.

introduction

Send mail event for each new email in IMAP INBOX.

synopsis

Start listening new mails :

const notifier = require('mail-watcher');

const imap = {
  user: "yourimapuser",
  password: "yourimappassword",
  host: "imap.host.com",
  port: 993, // imap port
  tls: true,// use secure connection
  tlsOptions: { rejectUnauthorized: false }
};

notifier(imap)
  .on('mail', mail => console.log(mail))
  .start();

Keep it running forever :

const n = notifier(imap);
n.on('end', () => n.start()) // session closed
  .on('mail', mail => console.log(mail.from[0].address, mail.subject))
  .start();

Note: If using a Gmail account, you will need to do two things:

1. Enable IMAP in your Gmail account settings, which is detailed here.
2. Authorize "less secure apps", which you is laid out in "Option 2" here.

installation

$ npm install mail-watcher

• authTimeout : Number of milliseconds to wait to be authenticated after a connection has been established. Default: 5000
• debug: function - if set, the function will be called with one argument, a string containing some debug info. Default: debug output if enabled.

Options from node-imap are also avaliable.

For backward compatibility username is supported.

custommDbg: function - if set, the function will be called with args that contain some mail-notifier debug info. Default: debug output if enabled.

example:

const n = notifier(config, (...args) => {
  const msg = util.format(...args);
  customLogFn(msg);
});

.start()

Start listening for incomming emails.

.stop()

Stop listening and close IMAP connection.

Events

'connected'

Sent when a connection to the server has been made.

'mail'

Sent on incoming new unread email. The parsed Mail is given as first parameter to the event listener.

'error'

Sent when an error occurs with the IMAP connection. The first parameter is the err object.

'end'

Sent when the IMAP connection is closed. This usually happens after a stop method call.

Dependencies

This module relies heavily on node-imap. For more advanced usage, please consider using it directly.

Debugging

Debugging is enabled via the visionmedia/debug module.

To enable debug info add mailnotifier to the DEBUG env variable :

$>DEBUG=mailnotifier node sample/simple-mail-notifier.js

Or to also have imap module debug info :

$>DEBUG=mailnotifier,imap node sample/simple-mail-notifier.js
