-------------------------------------------------------------------------------- 1 | NodeChat 2 | ======== 3 | 4 | NodeChat is a simple, scalable web-based chat server built on [Node.js](http://nodejs.org). 5 | 6 | 7 | Server 8 | ------ 9 | 10 | Creating a chat server is super simple. 11 | 12 | // create a server at http://localhost:8001 13 | var chat = require("lib/server"); 14 | var chatServer = chat.createServer(); 15 | chatServer.listen(8001); 16 | 17 | Once you've created a server, you can add channels. 18 | 19 | // create a channel at http://localhost:8001/chat 20 | var channel = chatServer.addChannel({ basePath: "/chat" }); 21 | 22 | Channels have three options: 23 | 24 | * `basePath` (required) - the URL to use for the channel 25 | * `messageBacklog` (default 200) - how many message to keep in memory 26 | * `sessionTimeout` (default 60) - how many seconds to wait before killing inactive sessions 27 | 28 | 29 | Client 30 | ------ 31 | 32 | NodeChat comes with a client library built on [jQuery](http://jquery.com) to make it easy to connect to a NodeChat server. 33 | 34 | // connect to a channel 35 | var channel = nodeChat.connect("http://localhost:8001/chat"); 36 | 37 | // join the channel 38 | channel.join("my-nick"); 39 | 40 | // send a message to the channel 41 | channel.send("hello"); 42 | 43 | // leave the channel 44 | channel.part(); 45 | 46 | 47 | Events 48 | ------ 49 | 50 | The server and client both emit events on the channel objects. 51 | 52 | * `join` - emitted when someone joins the channel. 53 | * `msg` - emitted when someone sends a message to the channel. 54 | * `part` - emitted when someone leaves the channel. 55 | 56 | Each event receives an object with the following properties: 57 | 58 | * `id` - unique id for the event (unique per channel). 59 | * `nick` - the nick of the user who performed the action. 60 | * `type` - the type of action (will be same as the event type). 61 | * `text` - text associated with the action. 62 | * `timestamp` - when the action occurred. 63 | 64 | In addition, the client emits a `connectionerror` event if the connection to the server is lost. 65 | 66 | 67 | Installation & Demo 68 | ------------------- 69 | 70 | To install: 71 | 72 | git clone http://github.com/scottgonzalez/node-chat.git 73 | 74 | To run the demo: 75 | 76 | ./node-chat/demo/chat.js 77 | Then open `http://localhost:8001` in a browser. 78 | 79 | 80 | License 81 | ------- 82 | 83 | Copyright 2013 Scott González.
