Example
-------
The listing below demonstrates a simple browser based JavaScript
Thrift client and Node.js JavaScript server for the hello_svc 
service. 

### hello.thrift - Service IDL
    service hello_svc {
      string get_message(1: string name)
    }

### hello.html - Browser Client
    <!DOCTYPE html>
    <html lang="en">
      <head>
        <meta charset="utf-8">
        <title>Hello Thrift</title>
      </head>
      <body>
        Name: <input type="text" id="name_in">
        <input type="button" id="get_msg" value="Get Message" >
        <div id="output"></div>
  
        <script src="thrift.js"></script>
        <script src="gen-js/hello_svc.js"></script>
        <script>
          (function() {
            var transport = new Thrift.Transport("/hello");
            var protocol  = new Thrift.Protocol(transport);
            var client    = new hello_svcClient(protocol);
            var nameElement = document.getElementById("name_in");
            var outputElement = document.getElementById("output");
            document.getElementById("get_msg")
              .addEventListener("click", function(){
                client.get_message(nameElement.value, function(result) {
                  outputElement.innerHTML = result;
                });
              });
          })();
        </script>
      </body>
    </html>

### hello.js - Node Server
    var Thrift = require('thrift');
    var TBufferedTransport = require('thrift/lib/thrift/transport').TBufferedTransport;
    var TJSONProtocol = require('thrift/lib/thrift/protocol').TJSONProtocol;
    var hello_svc = require('./gen-nodejs/hello_svc.js');
    
    var hello_handler = {
      get_message: function(name, result) {
        var msg = "Hello " + name + "!";
        result(null, msg);
      }
    }
    
    var hello_svc_opt = {
      transport: TBufferedTransport,
      protocol: TJSONProtocol,
      cls: hello_svc,
      handler: hello_handler
    };
    
    var server_opt = {
      staticFilePath: ".",
      services: {
        "/hello": hello_svc_opt
      }
    }
    
    var server = Thrift.createStaticHttpThriftServer(server_opt);
    var port = 9099;
    server.listen(port);
    console.log("Http/Thrift Server running on port: " + port);`
