ng2-websockets

Example project of using WebSockets in an Angular 2 application.

This project consists of two parts, a client (angular2.rc6) and server part (Nodejs 4.x).

Server

• Download or clone the repo and run npm install in the server directory to install server dependencies.
• Currently the server only has a dependency on js-websockets
• Run node server.js or nodemon server.js to start the server.
• The server is started on localhost:3005.

The only purpose of this simple server is to start a websocket server and accept incoming connections. Once a message is posted to the server, it is transformed by adding the local time to the incoming object and then echoed back to the client.

Client

• Download or clone the repo and run npm install to install dependencies.
• Make sure the server is already started before you try to start the client (as it is trying to connect to the ws-server on startup).
• run npm start to start the client.
• Typ a message in the messagebox. It should reappear in the list of messages.

Messages are always in the format of a Message-object in the following format:

interface Message {
	author: string,
	message: string,
	newDate?: string
}

the field newDate is added by the server.
