Chat Widget

Appcelerator Titanium Appcelerator Alloy License

This widget is an example of chat widget where the content is separated from the widget in such a way that any kind of model could be used with this widget. The widget uses builders to generate views corresponding to a message; This builders act as delegates so that the widget can focus its concern on displaying correctly those messages together.

Therefore, it handles the succession of messages in a TableView and gives easy ways to :

  • load older messages
  • add new message to the list
  • handle user inputs in a 'responsive' textArea

As a matter of fact, the widget is also a playground for new testing methods and tools. Then, It follows a continuous integration process where builds and tests are made in the cloud with travis.

How to install it

Comming on GitTio.

How to use it


First of all, the widget might be initialized once the windows is opened. This could be performed in the following way :

    $.index.addEventListener('open', function (e) {
            messageBuilder: messengerLike,

    // ... Do some awesome stuff


Others parameters might be supplied during the initialisation such as an initial set of messages. Please, have a look to the following documentation page for more info.

Listen to events

The widget may trigger two kind of events : load and newmessage. Both event are documented here.

The first one is fired each time the user is asking for older messages (i.e.: scrolling up); the event contains some useful pieces of information such as the last message currently displayed as well as callbacks to response to the widget.

    $.chat.on('load', function (loadEvent) {
        // Do some stuff do handle the request ...
        loadEvent.success(/* someOlderMessages */);

The second one is fired when the user has pressed the send button. The event holds data such as the content of the message and the date at which it has been send. Also, like the previous one, it offers two callbacks to handle success and error response. As the widget does not know how to create a message from a text content, the parent controller is supposed to supply an instance of the new message as an argument of the success callback.

    $.chat.on('newmessage', function (newMessageEvent) {
        // Do some stuff to handle the new message
        newMessageEvent.success(/* message */);

Add new messages to the widget

It is also possible to manually add new messages to the chat widget (for instance, when a new message is sent from an app, it may trigger a specific event to the app of the opposite user...). To do such a thing, just use the receive function which handle either a message or an array of messages.

    $.chat.receive(/* Tons of messages */);


Pull To Refresh

Message Builder

It also requires you to supply a message builder in order to render views. More info about message builders right here.
