服务器端Javascript函数

Question

Ok guys. I've built a web application with some friends that is somehow complex and took us some time to built. It is entirely built using JavaScript

Now the application has some functions which we don't want to readily share with the world(view-source).

The application works by sending an input to an algorithm and receiving the output from that algorithm and displays it on a canvas. (Thats how all functions work anyway:) )

Okay i don't know much about node.js but from what i've heard its server-side JavaScript. Does that mean that i can transfer the function server-side and using POST-GET to send an input and receive an output? All without having the source code of that particular function readily visible to anyone?

Please don't get started about how i should be more worried about doing things better rather than worrying about the safety of our work. I already know that so consider my question as a complimentary safeguard, at least for the time being.

Obfuscation is not a very concrete option since many developers de-obfuscate code just for fun.

This application is not like a hen with a golden egg and i am not being grandiose about this, but i was just having this question in my mind for some time now so i just shoot it here to know in the future how things work.

Thanks guys!

If you're worried about protecting your ultra sweet super secret codes, you could host your app and use a little something called RPC. Remote. Procedure. Calls.

Check out this little guy
https://github.com/deoxxa/pillion

It's built on burro, a sweet package I made
https://github.com/naomik/burro

Easy as 1-2-3 or ABC or cake or strippers or whatever else is easy

% npm install pillion burro && echo omg that was so easy

DISCLAIMER

I'm about to reveal a super secret greeting function that says hello to our clients. This is ultra secret intellectual IP properties and should not be shared with anyone on the internets.

You could provide the function calls you need using something like this on the server

// server.js
var net = require("net"),
    burro = require("burro"),
    pillion = require("pillion");

var server = net.createServer(function(_socket) {
  var socket = burro.wrap(_socket),
      rpc = new pillion(socket);

  rpc.provide("greet", function(name, cb) {
    cb("hi there, " + name);
  });
});

server.listen(3000);

Then on the client side

// client.js
var net = require("net"),
    burro = require("burro"),
    pillion = require("pillion");

var _socket = net.connect(3000),
    socket = burro.wrap(_socket),
    rpc = new pillion(socket);

rpc.callRemote("greet", "friend", function(res) {
  console.log(res); // prints "hi there, friend"
});
