Suspenders
Realtime Asynchronous WebSocket RPC Using SockJS
Socket.io is an exceptional idea, a drop in "all you need" WebSocket library which aims to provide all the tools necessary for common usage scenarios. Unfortunately v0.9 is currently a bit out of date, and doesn't seem to work as well as libraries like SockJS.
That's where Suspenders comes in - implementing some of the core functionality available in Socket.io on top of SockJS to give you all the easy to use features you're used to with the added stability of a proven and tested backing library which is fully compatible with the WebSocket spec.
Features
- Remote Function Calls allow you to call functions on the client and server across the wire
- Asynchronous Returns allow you to easily return information from the remote side's functions
- Function Namespacing allows you to layout your APIs in a logical and easy to navigate manner
Example
Server
var http = require('http'),
sockjs = require('sockjs'),
suspender = require('suspender');
var echo = sockjs.createServer();
echo.on('connection', function(conn) {
var sock = suspender(conn);
conn.on('ping', function() {
sock.call('pong');
});
conn.on('echo', function(data, done) {
return done(null, data);
});
conn.on('close', function() {});
});
var server = http.createServer();
echo.installHandlers(server, {prefix:'/echo'});
server.listen(9999, '0.0.0.0');Client
