Gmail.js - JavaScript API for Gmail

Note: The new Content Security Policy will prevent direct injection. Here is how to get around it

Note: This is not an official Gmail API, and isn't affiliated with Google.

Note: Gmail.js requires jQuery to work

TL;DR Summary

• Lots of api methods to work with gmail. Useful for chrome extensions
• Most of them dont take arguments, they work on what is currently visible on the screen
• I still need to add implementation for chrome extension, works by injecting js for now
• Main methods allow you to observe certain events with gmail.observe.on('lots_of_actions_here', callback()) or similar gmail.observe.before(...) and gmail.observe.after(...)
• Click on a method link to view more detailed docs
• Create an issue/pull request for feedback, requests and fixes

Examples

• Signal - Edit your inbox!
• Gmail Hacks by @arpitnext (Source)

Content Security Policy

The new Content Security Policy will prevent direct injection. Please see the following repository to get around the policies. More details can also be found in issue #75

Setup

• Gmail.js requires jQuery to work

Quick Usage - Chrome Console

// {inject jquery.js} by copy pasting this in your console
var jq = document.createElement('script');
jq.src = "https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js";
document.getElementsByTagName('body')[0].appendChild(jq);

// {inject gmail.js} by copy pasting gmail.js contents or via url like jquery above
// var Gmail = {.....} // paste gmail.js code here

// start using!
// you can also pass in a reference to jQuery upon init - Gmail(localJQuery)
var gmail = Gmail();
gmail.get.user_email();

gmail.observe.actions()

Similar to gmail.obsere.http_requests() this keeps track of the last 10 gmail actions (vs all http requests). Actions here correspond to things like clicking refres, archiving, deleting, starring etc.

gmail.observe.on(action, callback)

This is the key feature of gmail.js. This method allows you to add triggers to all of these actions so you can build your custom extension/tool with this library.

You simply specify the action nane and your function that the method will return data to when the actions are triggered and it does the rest. You can have multiple triggers

Your callback will be fired directly after Gmail's XMLHttpRequest has been sent off the the Gmail servers.

Available Actions

• poll - When gmail automatically polls the server to check for new emails every few seconds
• new_email - When a new email appears in the inbox
• open_email - When a new email appears in the inbox
• refresh - When you click the refresh button
• unread - When a conversation(s) is marked unread
• read - When a conversation(s) is marked read
• delete - When a conversation(s) is deleted
• delete_message_in_thread - When a conversation(s) is deleted inside and is part of a thread
• mark_as_spam - When a conversation(s) is marked as spam
• mark_as_not_spam - When a conversation(s) is unchecked as spam
• label - When a conversation(s) get applied a label
• archive - When a conversation(s) is archieved
• move_to_inbox - When a conversation(s) is moved to the inbox
• delete_forever - When a conversation(s) is deleted forever
• star - When a conversation(s) is starred
• unstar - When a conversation(s) is unstarred
• mark_as_important - When a conversation(s) is marked as important
• mark_as_not_important - When a conversation(s) is marked as not important
• filter_messages_like_these - When a filter button is triggered for a conversation
• mute - When a conversation(s) is muted
• unmute - When a conversation(s) is unmuted
• add_to_tasks - When an item is added to google tasks
• move_label - When a conversation(s) is moved to a label folder
• save_draft - When a draft is saved
• discard_draft - When a draft is dicarded
• send_message - When a message is sent
• expand_categories - When a category is expanded from the left nav sidebar
• restore_message_in_thread - When a deleted message is restored inside a thread
• delete_label - When a label is deleted
• show_newly_arrived_message - When inside an email and a new email arrives in the thread

The on method also supports observering specific DOM events in the Gmail Interface (for example when a new compose window is opened). These are only available via the on method (not the before or after methods).

Some actions/observers also have defined 'sub-observers' which become available if you have an action bound to the parent observer. Sub-observers are defined as such because they only make sense once the parent has been triggered. I.e. for an individual email to display as part of a conversation thread, the thread must first be opened/loaded in the interface.

Example usage:

gmail.observe.on('view_thread', function(obj) {
  console.log('view_thread', obj);
});

// now we have access to the sub observers view_email and load_email_menu
gmail.observe.on('view_email', function(obj) {
  console.log('view_email', obj);
});

Available DOM Actions/Observers & Sub-observers

• load - When the gmail interface has completed loading
• compose - When a new compose window opens, or a message is replied to or forwarded
• recipient_change - When the recipient (to, cc or bcc) is changed when composing a new email or replying/forwarding an email
• view_thread - When a new coversation thread is opened
• view_thread Sub-observers
• view_email - When an individual email is loaded within a thread (also fires when thread loads displaying the latest email)
• load_email_menu - When the dropdown menu next to the reply button is clicked

gmail.observe.before(action, callback)

Similar to gmail.observe.on, this method allows you to bind callbacks to specific events.

All of the standard actions in gmail.observe.on work here, with the exception of the DOM actions

The main difference between on and before is that these callbacks are fired before Gmail's XMLHttpRequest has been sent off the the Gmail servers.This means, where relevant, your callback function can change it prior to it departing by editing the xhrParams.body_params object in the passed xhr parameter.

gmail.observe.before('send_message', function(url, body, data, xhr){
  var body_params = xhr.xhrParams.body_params;

  // lets cc this email to someone extra if the subject is 'Fake example'
  if(data.subject == 'Fake example') {
    if(body_params.cc) {
      if(typeof body_params.cc != 'object') body_params.cc = [ body_params.cc ];
    } else {
      body_params.cc = [];
    }
    body_params.cc.push('brent@zeald.com');
  }

  // now change the subject
  body_params.subject = 'Subject overwritten!';
  console.log("sending message, url:", url, 'body', body, 'email_data', data, 'xhr', xhr);
});

gmail.observe.after(action, callback)

Similar to gmail.observe.on, this method allows you to bind callbacks to specific events.

All of the standard actions in gmail.observe.on work here, with the exception of the DOM actions

The main difference between on and after is that these callbacks are fired once Gmail's XMLHttpRequest has returned from the Gmail servers (on the XMLHttpRequest onreadystatechange event).

In addition to the usual parameters received by a callback, callbacks you define for an after event receive an additional response parameter prior to the last xhr parameter. This response parameter is a parsed object representation of the response from the Gmail servers.

So for example, the send_message action would receive:

gmail.observe.after("send_message", function(url, body, data, response, xhr) {
  console.log("message sent", "url:", url, 'body', body, 'email_data', data, 'response', response, 'xhr', xhr);
})

gmail.observe.off(action=null,type=null)

Turn off an observe action. Providing it no argument will disable all observers.

Type is either before, after, on or dom. If not specified will disable all types of specified observer.

gmail.observe.on('poll', function(x,y,z){});
gmail.observe.before('refresh', function(x,y,z){});
gmail.observe.after('send_message', function(x,y,z){});

gmail.observe.off('poll','on'); // disables on poll
gmail.observe.off('poll'); // disables all poll events of any type
gmail.observe.off(null,'before'); // disables all before observers
gmail.observe.off();  // disables all

gmail.observe.register(action, class/args, parent=null)

Allow an application to register a custom DOM observer specific to their application. Adds it to the configured DOM observers that will then be supported by the dom insertion observer. Note this method must be called prior to binding any handlers to specific actions/observers using on, before or after. Once you start binding handlers, you cannot register any further custom observers.

This method can be called two different ways:

Simple:

• action - the name of the new DOM observer
• class - the class of an inserted DOM element that identifies that this action should be triggered
• parent - optional - if specified, this observer will be registered as a sub_observer for the specified parent (meaning it will only be checked for if the parent observer has something bound to it, and has been triggered).

Complex:

• action - the name of the new DOM observer
• args - an object containin properties for each of the supported DOM observer configuration agruments:
  • class - the class of an inserted DOM element that identifies that this action should be triggered
  • selector - if you need to match more than just the className of a specific element to indicate a match, you can use this selector for further checking (uses element.is(selector) on matched element). E.g. if there are multiple elements with a class indicating an observer should fire, but you only want it to fire on a specific id, then you would use this
  • sub_selector - if specified, we do a jquery element.find for the passed selector on the inserted element and ensure we can find a match
  • handler - if specified this handler is called if a match is found. Otherwise default calls the callback & passes the jQuery matchElement
• parent - optional - as above with simple

// this will register an observer that fires each time the autosuggest listbox pops up / changes
// as you type an email address into a compose
gmail.observe.register('compose_email_select', {
  class: 'Jd-axF',
  selector: 'div.Jd-axF:first-child'
});
gmail.observe.on('compose_email_select', function(match) {
  console.log('Email select popup',match);
});

gmail.dom.compose(compose_el)

An object used to abstract interation with a compose popup

gmail.dom.email(email_el or email_id)

An object for interacting with an email currently present in the DOM. Represents an individual email message within a thread, and provides a number of methods and properties to access & interact with the interface and email data.

Expects a jQuery DOM element for the email div (div.adn as returned by the view_email observer), or an email_id

• .id - property storing the id of the email
• .body([body]) - allows get/set the html body in the DOM
• .to([to_array]) - allows retrieve or updating to/from DOM who the email is addressed to
• .from([email_address],[name]) - allows get/set who the email is from in the DOM
• .data() - retrieves object of email data from the Gmail servers
• .source() - retrieves the email raw source from the Gmail servers
• .dom() - retrieves the primary element, or other defined elements from the DOM

gmail.dom.email.body([body=null])

Get/Set the full email body as it sits in the DOM. Note: This gets & sets the body html after it has been parsed & marked up by GMAIL. To retrieve it as it exists in the email message source, use a call to .data()

If you want the actual DOM element use .dom('body');

Receives optional argument containing html to update the email body with.

var email = new gmail.dom.email(email_id); // optionally can pass relevant $('div.adn');
var body = email.body();
var id = email.id;

// add a heading at the start of the email and update in the interface
email.body('<h1>My New Heading!</h1>' + body);

gmail.dom.email.to([to_array=null])

Get/Set who the email is showing as To. Optionally receives an array of objects containing email and/or name properties. If received replaces the values in the DOM. Returns an array of objects containing email & name of who is showing in the DOM as the email is to.

var email = new gmail.dom.email(email_id);
var to = email.to();
console.log('Email is to', to); // [{email: 'user@user.com', name: 'Display Name'}, {email: 'user2@user.com', name: 'User Two'}]

// update values that appear in the interface. This supports the popup hovers in gmail interface etc
to = email.to([
  {email: 'user@user.com', name: 'Display Name'},
  {email: 'user2@user.com', name: 'User Two'}
]);

gmail.dom.email.from([email_address=null], [display_name=null])

Get/Set the sender of the email that is displayed in the interface. Optionally receives email and name properties. If received updates the values in the DOM Returns an object containing email & name of the sender and dom element

var email = new gmail.dom.email(email_id);
var from = email.from();
console.log('Email is from', from); // {email: 'user@user.com', name: 'Display Name'}

// update who the email is from in the interface
from.name = 'New Name';
email.from(from);

gmail.dom.email.data()

Retrieve relevant email data from the Gmail servers for this email Makes use of the gmail.get.email_data() method Returns an object containing the email data. Caches email data for all emails in the thread

var email = new gmail.dom.email(email_id);
var data = email.data();
console.log('Email data is',data);

gmail.dom.email.source()

Retrieve email source for this email from the Gmail servers Makes use of the gmail.get.email_source() method Returns string of email raw source

var email = new gmail.dom.email(email_id);
var source = email.source();
console.log('Email source is',source);

gmail.dom.email.dom([lookup=null])

Retrieve preconfigured dom elements for this email Abstracts relevant dom elements so code can be centralized - making it easier to update if Gmail updates its interface Retrieves the primary DOM element if you pass no lookup Supported lookups: - null (primary element) - body - from - to - to_wrapper - timestamp - star - reply_button - menu_button - details_button

var email = new gmail.dom.email(email_id);
var el = email.dom();
var to_dom = email.dom('to');
console.log('El is',el,'To elements are',to);

gmail.dom.thread(thread_el)

An object for interacting with a conversation thread currently present in the DOM. Provides methods to access & interact with the interface.

Expects a jQuery DOM element for the thread wrapper div (div.if as returned by the view_thread observer)

• .dom() - retrieves the primary element, or other defined elements from the DOM

gmail.dom.thread.dom([lookup=null])

Retrieve preconfigured dom elements for this conversation thread Abstracts relevant dom elements so code can be centralized - making it easier to update if Gmail updates its interface Retrieves the primary DOM element if you pass no lookup Supported lookups: - null (primary element) - opened_email - subject - labels

var thread = new gmail.dom.thread($('div.if'));
var el = thread.dom();
var subject = thread.dom('subject');
console.log('El is',el,'Subject element is',subject);

gmail.tools.add_toolbar_button(content_html, onclick_action, custom_style_class)

Add a new button to Gmail Toolbar

gmail.tools.add_toolbar_button('content_html', function() {
  // Code here
}, 'Custom Style Classes');

gmail.tools.add_compose_button(compose_ref, content_html, onclick_action, custom_style_class)

Add button to compose window. You can use gmail.dom.composes() to get compose reference.

var compose_ref = gmail.dom.composes()[0];
gmail.tools.add_compose_button(compose_ref, 'content_html', function() {
  // Code here
}, 'Custom Style Classes');
