CodersTV Chat

Smart package for CodersTV' chat. It does not persist messages on Mongo.

Install

To install in a new project:

> meteor add coderstv:chat

Quick Start

You need to configure at least one kind of account. Supported social plataforms now are:

• Facebook
• Google

For example, with Google:

meteor add accounts-google

<template name="index">
  {{> chatroom}}
  {{> loginButtons}}
</template>

Required Configuration

Host (Room)

Host is the same thing as room. To set a host, just do on your code:

Session.set('chatHost', 'room1');

If that session var is empty, Chat will try to get the current Path (See Path definition above).

Path

If you don't want to have a global chat for entire website, you can set a Path so you can have a different chat box for each Path you set. What's needed to do on javascript part is set a Path. Path is a reactive source of current page path (like window.location.pathname). So, whenever it changes, it must be updated calling Path.set(path)

Users information

Users info will be at the Meteor.users document.

To get users info, first, you need to manually expose users with the superchat attribute. For example, on your code, publish the users:

// server
Meteor.publish('chatUsers', function () {
  return Meteor.users.find({/* add your filter*/}, {fields: {superchat: 1}});
});

Then, subscribe to the publication and turn on the subscripitions ready flag (also on your code):

Meteor.subscribe('chatUsers', function () {
  Session.set('chatSubsReady', true);
});

Now you are going to have users information on chat.

Other config and example

Example with iron-router

Router.map(function () {
  this.route('index', {
    path: '/',
    before: function () {
      Path.set(Router.current().location.get().path);
    }
  });
});

Making height responsive

Template.parentTemplate.rendered = function() {
	$(window).resize(function () {
		var height = $(this).height(); // you can set a value you want here
		$('#chat-wrapper').height(height);
	});
	$(window).resize(); // trigger the resize
}

Tracking users online

You will have to set up the Meteor-presence publication and subscription:

/* On Server */
Meteor.publish('superChatUserPresence', function (whereAt) {
  var filter = whereAt ? {'state.whereAt': whereAt} : {};

  return Meteor.presences.find(filter, {fields: {state: true, userId: true}});
});

/* On Client */
Meteor.Presence.state = function() {
  return {
    online: true,
    whereAt: Path()
  };
}

Deps.autorun(function () {
  Meteor.subscribe('superChatUserPresence', Path());
});

Number of messages on chat area and default profile image

Just put on the client, on startup (if you override the default object, make sure you put all those params):

Superchat = {
  messageLimitOnScreen: 50,
  defaultProfilePicture: 'http://i.imgur.com/HKSh9X9.png'
};
