Simple IMAP client for node.js

Primary LanguageJavaScript

inbox

This is a work in progress IMAP client for node.js.

The project consists of two major parts

  • IMAP command parser (token based, more or less complete)
  • IMAP control for accessing mailboxes (under construction)

Build Status

Installation

Install from npm

npm install inbox

API

NB! This API is preliminary and may change.

Use inbox module

var inbox = require("inbox");

Create new IMAP connection

Create connection object with

inbox.createConnection(port, host, options)

where

  • port is the port to the server (defaults to 143 on non-secure and to 993 on secure connection)
  • host is the hostname of the server
  • options is an options object for auth etc.
  • options.secureConnection is a Boolean value to indicate if the connection is initially secure or not
  • options.auth is an authentication object
  • options.auth.user is the IMAP username
  • options.auth.pass is the IMAP password
  • options.auth.XOAuthToken (optional) is either a String or inbox.createXOAuthGenerator object

Example:

var client = inbox.createConnection(false, "imap.gmail.com", {
    secureConnection: true,
    auth:{
        user: "test.nodemailer@gmail.com",
        pass: "Nodemailer123"
    }
});

Or when login with XOAUTH (see examples/xoauth.js)

var client = inbox.createConnection(false, "imap.gmail.com", {
    secureConnection: true,
    auth:{
        XOAuthToken: inbox.createXOAuthGenerator({
            user: "test.nodemailer@gmail.com",
            token: "1/Gr2OVA2Ol64fNyjZCns-bkRau5eLisbdlEa_HSuTaEk",
            tokenSecret: "ymFpseHtEnrIsuL8Ppbfnnk3"
        })
    }
});

Once the connection object has been created, use connect() to create the actual connection.

client.connect();

When the connection has been successfully established a 'connect' event is emitted.

client.on("connect", function(){
    console.log("Successfully connected to server");
});

List available mailboxes

To get the list of available mailboxes, use

client.getMailboxList()

which returns the mailbox list

Example

console.log(client.getMailboxList());

Output:

{ 
    INBOX: { name: 'INBOX', inbox: true },
    Drafts: { name: 'Drafts' },
    Sent: { name: 'Sent', disabled: true},
    Junk: { name: 'Junk' }
}

Select a mailbox

Before you can check mailbox contents, you need to select one with

client.openMailbox(name[, options], callback)

Where

  • name is the name of the mailbox (ie. "INBOX")
  • options is an optional options object
  • options.readOnly - if set to true, open the mailbox in read-only mode (downloading messages does not update seen/unseen flag)
  • callback (error, mailbox) is a callback function to run after the mailbox has been opened. Has an error param in case the opening failed and a mailbox param with the properties of the opened mailbox.

Example

client.on("connect", function(){
    client.openMailbox("INBOX", function(error, mailbox){
        if(error) throw error;
        console.log("Message count in INBOX: " + mailbox.count);
    });
});

Listing e-mails

Once a mailbox has been opened you can list contained e-mails with

client.listMessages(from[, limit], callback)

Where

  • from is the index of the first message (0 based), you can use negative numbers to count from the end (-10 indicates the 10 last messages)
  • limit defines the maximum count of messages to fetch, if not set or 0 all messages from the starting position will be included
  • callback (error, messages) is the callback function to run with the message array

Example

// list newest 10 messages
client.listMessages(-10, function(err, messages){
    messages.forEach(function(message){
        console.log(message.UID + ": " + message.title);
    });
});

Example output for a message listing

[
    { 
        // if uidvalidity changes, all uid values are void!
        UIDValidity: '664399135',
        
        // uid value of the message
        UID: 52,
        
        // message flags (Array)
        flags: [ '\\Flagged', '\\Seen' ],
        
        // date of the message (Date object)
        date: Wed, 25 Apr 2012 12:23:05 GMT,
        
        title: 'This is a message, may contain unicode symbols',
        
        // single "from:" address
        from: { 
            name: 'Andris Reinman', 
            address: 'andris.reinman@gmail.com' 
        },
        
        // an array of "to:" addresses
        to: [
            {
                name: 'test nodemailer',
                address: 'test.nodemailer@gmail.com'
            }
        ],
        
        // an array of "cc:" addresses
        cc: [
            {
                name: 'test nodemailer',
                address: 'test.nodemailer@gmail.com'
            }
        ],
        
        messageId: '<04541AB5-9FBD-4255-81AA-18FE67CB97E5@gmail.com>' 
    },
    ...
]

NB! if some properties are not present in a message, it may be not included in the message object - for example, if there are no "cc:" addresses listed, there is no "cc" field in the message object

Fetch message details

To fetch message data (flags, title, etc) for a specific message, use

client.fetchData(uid, callback)

Where

  • uid is the UID value for the mail
  • callback (error, message) is the callback function to with the message data object (or null if the message was not found). Gets an error parameter if error occured

Example

client.fetchData(123, function(error, message){
    console.log(message.flags);
});

Fetch message contents

Message listing only retrieves the envelope part of the message. To get the full RFC822 message body you need to fetch the message.

var messageStream = client.createMessageStream(uid)

Where

  • uid is the UID value for the mail

Example (output message contents to console)

client.createMessageStream(123).pipe(process.stdout, {end: false});

NB! If the opened mailbox is not in read-only mode, the message will be automatically marked as read (\Seen flag is set) when the message is fetched.

Message flags

You can add and remove message flags like \Seen or \Answered with client.addFlags() and client.removeFlags()

Add flags

client.addFlags(uid, flags, callback)

Where

  • uid is the message identifier
  • flags is the array of flags to be added
  • callback (error, flags) is the callback to run, gets message flags array as a parameter

Remove flags

client.removeFlags(uid, flags, callback)

Where

  • uid is the message identifier
  • flags is the array of flags to be removed
  • callback (error, flags) is the callback to run, gets message flags array as a parameter

Example

// add \Seen and \Flagged flag to a message
client.addFlags(123, ["\\Seen", "\\Flagged"], function(err, flags){
    console.log("Current flags for a message: ", flags);
});

// remove \Flagged flag from a message
client.removeFlags(123, ["\\Flagged"], function(err, flags){
    console.log("Current flags for a message: ", flags);
});

Wait for new messages

You can listen for new incoming e-mails with event "new"

client.on("new", function(message){
    console.log("New incoming message " + message.title);
});

Complete example

Listing newest 10 messages:

var inbox = require("inbox");

var client = inbox.createConnection(false, "imap.gmail.com", {
    secureConnection: true,
    auth:{
        user: "test.nodemailer@gmail.com",
        pass: "Nodemailer123"
    }
});

client.connect();

client.on("connect", function(){
    client.openMailbox("INBOX", function(error, mailbox){
        if(error) throw error;
        
        client.listMessages(-10, function(err, messages){
            messages.forEach(function(message){
                console.log(message.UID + ": " + message.title);
            });
        });

    });
});
