Sock-Hook

A web hook for a web socket broadcast server.

Install

NPM

npm install sock-hook

var sockhook = require('sock-hook')

Manual

var sockhook = require('<path_to_file>/sock-hook.js')

Use

Server Creation

Currently only http or https is supported, not both at once.

var sock = require('sock-hook');

// first object is api config, second is socket server config
sock.createServer({port: 80}, {port:8080});

Options

An options object is used to store all options for the sock-hook server.

NOTE: The "api-server" port may not be the same as the "socket-server" port.

{
	"api-server": {
		"port": 80,
		"ssl": {
			"cert": "<path_to_cert>",
			"key": "<path_to_key>",
			"ca": "<path_to_ca>",
			"<express SSL options>..."
		}
	},
	"socket-server": {
		"port": 8080,
		"cors": ["*"],
		"ssl": {
			"cert": "<path_to_cert>",
			"key": "<path_to_key>",
			"ca": "<path_to_ca>"
		}
	}
}

SSL

Both the API and Socket Server have the ability to use https, the same or different ssl credentials can be used for both.

NOTE:* You may pass in a file path to the certs or the 'utf-8' contents of the cert/key files.

var sock = require('sock-hook');

// to read ssl files
var fs = require('fs');

// ssl file options
var options = {
  cert: <path_to_cert>,
  key: <path_to_key>
}

// first object is api config, second is socket server config
sock.createServer({port: 80, ssl: options}, {port: 8080, ssl: options});

Cors

For the "api-server" configuration you may setup CORS to restrict the API relay access. This is set up by passing an array of allowed URLs in the "api-server" options.

...
"cors": ["*"],
...

Routes

sock-hook uses express for the api routing.

Access the router and add a custom express route.

Then access the socket server and forward the data.

var sock = require('sock-hook');

var server = sock.createServer({port: 80}, {port:8080});

// router object
var router = server.router;

// socket server object
var socketServer = server.socketServer.wicker;

// route
router.post('/send',function(req,res) {
	// send to all connections
	socketServer.sendToAll(req.body);
	res.sendStatus(200);
});
