Load scripts dynamicly with websocket

Websocket script loader

Load scripts dynamicly with websocket instead of individual http-requests.

This code is not stable, just a demo to verify that it works

This is not optimal, it does not work with the browsers cache so this is someting that needs to be implemented by the site owner

Usage

The base stuff is really simple:

1. Ask the server for a script file
2. Server finds that script file and sends the contents
3. Client receives the script file contents and adds it to the DOM

Server

The server is done using node with the ws plugin.

$ node server.js

Client

On the client site you need to include client.js, check the very simple test.html

<script src="client.js"></script>

This will just do the demo, downloading jquery-1.11.0.min.js and alert.js from the server and add them to the DOM in script elements.

jquery-1.11.0.min.js is jQuery downloaded and stored on the server. alert.js is just an example, it alerts:

Well hello, websocket dynamic script loading worked!

Look at your html and you will find the following:

<script data-script-url="js/jquery-1.11.0.min.js" type="text/javascript">jquery content...</script>
<script data-script-url="js/alert.js" type="text/javascript">alert("Well hello, websocket dynamic script loading worked!");</script>
