roomsjs - streaming live data built to support different transporters

A Javascript Node.JS module, provides a way to send and receive messages and switch different transporters for creating rooms and streaming data between users, streaming data from a database and even stream from a 3rd party CDN. roomsjs, roomsdb and roomsjs-client together combine a powerful light-weight backend/front-end libraries built to stream live data and solve same problems related to real-time communications.

This library is split into three projects:

1. roomsjs - https://github.com/eladelrom/roomsjs
2. rooms.db - https://github.com/eladelrom/roomsdb
3. roomsjs-client - https://github.com/eladelrom/roomsjs-client

Node.js technology relatively young and memory leaks were found in socket.io and issues around engine.io's Websocket transporter on certain nodejs version.

The API was built to allow you to just 'switch' and use any transporter and create your own implementation. Module also have additional feature to help managing rooms easily.

The idea is to give a simple API and allowing using different transporters and modify the client implementation instead of having to do an 'open heart surgery' when you are already committed to one transporter API or another. It's recommended to use engine.io since it's the high level API of socket.io, however there are cases where you want to have the socket.io bloated code for certain functionality. rooms.js is a lower level API, just like socket.io, however it's lighter weight and doesn't have the sugar and all the bell and whistle of socket.io, so it's here for you to use.

roomsjs has features such as:

1. Connect to a room
2. Register a user
2. Request number of users
3. Private message
4. Video
5. Create multiple rooms
6. Store states
7. Subscribe to data VO
8. AMS/FMS Flash Webcam fallback
9. Ability to register internal robot to send messages
11. Switch different transporters: currently supporting `socket.io`, `engine.io` and `SockJS`.
10. Database connector (such as mysql, mongodb).
12. Angularjs implementation
13. Create Express HTTP service connecting to databases with websocket using same code
14. Add multiple nodejs apps interact as a client

Installation

Install with the Node.JS package manager npm:

  $ npm install roomsjs
  $ npm install rooms.db

Download the front-end roomjs min file: https://raw.github.com/eladelrom/roomsjs-client/master/client/dist/libs/rooms.min.js

Or install with bower:

bower install roomsjs-client

Quick getting started example

create a project and install packages:

cd ~/dev mkdir rooms && cd $_ npm install roomsjs rooms.db express

Server code to create the rooms, services and connect to database and/or 3rd party APIs for streaming;

Here is an example of an internal Robot signing in as a user:

The full working example is here: roomsjs-client/client/examples/collaborate.

Here is an example of having multiple peers (other nodejs apps) interacting with a room. You can join and register a user as well as send/receive messages just as a Web Client;

Rooms.db services examples: https://github.com/eladelrom/roomsdb

Front-end example of getting the number of visitors and data from external sources:

Examples of front-end implementation of rooms includes connecting to engine.io, socket.io and sockjs see here: https://github.com/eladelrom/roomsjs-client
