title: How to handle a get request with node.js (express)
body: <p>I'm a node.js newbie and I'm creating my first big app with it (I'm using express). I need to have my webpage perform some javascript canvas-drawing when the user loads an id with a get request, e.g.</p>
  
  <pre><code>www.mywebsite.com/page?id=22
  </code></pre>
  
  <p>I know I can handle this with a simple</p>
  
  <pre><code>var express        =        require("express");
  var app            =        express();
  app.get('handle',function(request,response){
      //request.id
  });
  </code></pre>
  
  <p>but I don't know how to start my webpage with the asked drawing for that id. Every tutorial on the internet on express and get explains how to handle get requests... well this question is about "what happens next?"</p>
  
  <p>Rephrased: I'm not sure how should I tell the html page "<em>you need to draw what is associated with this id</em>" from express and then send that page back to the user.</p>
