Mail-listener2 library for node.js. Get notification when new email arrived to inbox or when message metadata (e.g. flags) changes externally. Uses IMAP protocol.

We are using these libraries: node-imap, mailparser.

Heavily inspired by mail-listener.



npm install mail-listener2

JavaScript Code:

var MailListener = require("mail-listener2");

var mailListener = new MailListener({ username: "imap-username", password: "imap-password", host: "imap-host", port: 993, // imap port tls: true, connTimeout: 10000, // Default by node-imap authTimeout: 5000, // Default by node-imap, debug: console.log, // Or your custom function with only one incoming argument. Default: null tlsOptions: { rejectUnauthorized: false }, mailbox: "INBOX", // mailbox to monitor searchFilter: ["UNSEEN", "FLAGGED"], // the search filter being used after an IDLE notification has been retrieved markSeen: true, // all fetched email willbe marked as seen and not fetched next time fetchUnreadOnStart: true, // use it only if you want to get all unread email on lib start. Default is false, mailParserOptions: {streamAttachments: true}, // options to be passed to mailParser lib. attachments: true, // download attachments as they are encountered to the project directory attachmentOptions: { directory: "attachments/" } // specify a download directory for attachments });

mailListener.start(); // start listening

// stop listening //mailListener.stop();

mailListener.on("server:connected", function(){ console.log("imapConnected"); });

mailListener.on("server:disconnected", function(){ console.log("imapDisconnected"); });

mailListener.on("error", function(err){ console.log(err); });

mailListener.on("mail", function(mail, seqno, attributes){ // do something with mail object including attachments console.log("emailParsed", mail); // mail processing code goes here });

mailListener.on("attachment", function(attachment){ console.log(attachment.path); });

// it's possible to access imap object from node-imap library for performing additional actions. E.x. mailListener.imap.move(:msguids, :mailboxes, function(){})

That's easy!


Attachments can be streamed or buffered. This feature is based on how mailparser handles attachments. Setting

attachments: true
will download attachments as buffer objects by default to the project directory. A specific download directory may be specified by setting
attachmentOptions: { directory: "attachments/"}
. Attachments may also be streamed using
attachmentOptions: { stream: "true"}
. The
event will be fired every time an attachment is encountered. Refer to the mailparser docs for specifics on how to stream attachments.
