About

Socketry allows for an easy way to set up websocket servers and clients. It is built to allow anybody to easily set up websockets without any hastle.

-

Use

Socketry has an easy way to access all of the clients connected to the server.

const Socket = require('./index.js');
const server = new Socket.Server(8080);
 
console.log(server.clients); // array

You can filter through these clients to target the current client as well, since each client has their own unique id. You can find it by just using client.id.

-

Basic server file

To start using socketry, you will need a server file.

const Socket = require('./index.js');
// Create a new server on port `8080`
const server = new Socket.Server(8080);
// Create a room that messages will be sent to (can have multiple rooms)
const room = new server.Room('foo');
const room2 = new server.Room('bar');
 
// Fires when a client connects to the server
server.on('connection', usr => {
    console.log('User connected!');
    
    // Fires when the client closes or disconnects from the server
    usr.on('end', extUsr => {
        console.log('User Disconnected');
    });
    
    // fires when a message is sent to the server
    usr.on('message', (data, room) => {
        // Parse the data so that you can use each part
        data = JSON.parse(data);
        console.log(data);
        // Sends the message back to every client in the room
        room.clients.forEach(c => {
            c.send(`${data.usr}: ${data.msg}`);
        });
    });
});

This is just the barebones of a server. It just receives the websockets, and sends them out again to each client.

-

Basic client file

You will also need a way to communicate to the server. You can do this in node by using another barebones file.

const Socket = require('./index.js');
// Create a client that connects to localhost, on port `8080`
const socket = new Socket.Client('ws://localhost:8080');
 
// Fires when connected to a server
socket.on('open', usr => {
    // Join a room
    socket.joinRoom('foo');
    socket.joinRoom('bar');
 
    console.log('Connected!');
 
    // Fires when the client joins the room
    socket.on('join', room => {
        console.log('Joined Room');
        // Fires when server sends a message to the client in the room
        room.on('message', (msg) => {
            console.log(msg);
        });
 
        // Send a message to the server in object form.
        socket.send({msg: 'Message', usr: 'SharkFin'});
 
        // Leave the room
        room.leave();
 
        // Close the websocket connection 
        // socket.end();
    });
 
    // Fires when the client leaves a room
    socket.on('leave', room => {
        console.log('Left Room');
    });
});

Rooms

The websockets are split into rooms. This means that you can have something that acts as two or more servers, when it's really just one! This means you can host the socket server on one node process. The server can do whatever it wants with the rooms messages. When a message is recieved, the server can send it to all teh clients in the room, just a few clients, or to every room. This would be good for if you wan't to make announcements to every room about an event or such.

.send()

When sending with the client, you send an object. You can have any property inside the object, as long as the server will accept it.
