socketcoordinator v0.2.0

A module to use socket.io to connect a device meant to be controlled to a controller.

Getting Started

Install the module with: npm install socketcoordinator

var socketcoordinator = require('socketcoordinator');

Install with cli command

$ npm install -g socketcoordinator

Documentation

It is expected that the device being controlled can give the user an access token, given to the device when connecting to the server. This token will be inputted on the controlling device which will link the two together.

Examples

Server

var app = require('http').createServer();

var socketcoordinator = require('socketcoordinator').start(app);

app.listen(3000);

Device Client

var client = require('socket.io-client')('http://localhost:3000');

// use create if you have the ability to display the ID to the user
// To use a hard coded ID (ie one that is printed on the device)
// use .emit('start', hardCodedID, function()
client.emit('create', function(err, id){
    if(err) throw err;

    console.log(id);
});

client.on('message', function(command){
    // handle command from server
    console.log(command);
});

// Send data ever second to controlling device
setInterval(function(){
    socket.emit('message', 10);
}, 1000);

Controlling Client

var client = require('socket.io-client')('http://localhost:3000');

var token = '1234'; // Token shown by device

// err can equal noTokenServerFound
// Meaning that a device with that token is not connected to the server
client.emit('join', function(err){
    if(err) throw err;

    client.on('message', function(command){
        // handle command from server
        console.log(command);
    });

    // Send message ever second to device
    setInterval(function(){
        socket.emit('message', {move: 10});
    }, 1000);
});
