Node.JS [url removed, login to view] Realtime communication web chat


Currently we have a chat box 1:1 build on HTTP polling using jquery and [url removed, login to view]

We need to scale to >500 concurrent users.

What we have in mind is the following:

There is a back end server JSON API (we have developed)

[Development part 1] NODE.JS SERVER

The client (browser) sents events using websockets ([url removed, login to view]) tot the Node.js server application. Events are dispatched to the clients that needs the events (/information).

StartSession -> all users gets a websocket message there is a new user

ModifySession -> all users get an update of the user

SentToken -> Person who receives the token gets a messsage

LogOut -> Everybody gets an update the person has left

SentChatMessage -> the person to which the message is sent gets the msg

Typing -> For the active-session the person can see the user is typing

Stop_Typing -> for the active-session the person can see the user stopped typing.

... and a few more events

There are 2 events that a streaming server will sent to the node.js application with JSON:



These 2 events will be sent using JSON REST. So the node.js server needs also be able to handle JSON messages.

The node.js server application is a sort of state machine that processes and dispatches events. It must be lightweighted and does not call any back end services eg mysql server.

[Development part 2] CLIENT CODE HTML5

We need code in JS using [url removed, login to view] for sending the events as in part 1 and the corresponding receiving of the events dispatched to the html elements (DIV) that needs to be updated.
