express

node.js apps that use the popular express framework can be hosted in IIS.

• Express framework can be installed on Windows using NPM.
• Remember that you may or may not own the entire URL space within an express application when designing your URL structure - see code below.
• The URL rewrite module is recommended for all but the most simple express applications hosted in IIS. The sample below shows how to use it, but also check out the urlrewrite sample.

code

var express = require('express');

var app = express.createServer();

app.get('/node/express/myapp/foo', function (req, res) {
    res.send('Hello from foo! [express sample]');
});

app.get('/node/express/myapp/bar', function (req, res) {
    res.send('Hello from bar! [express sample]');
});

app.listen(process.env.PORT);

web.config

<configuration>
  <system.webServer>

    <!-- indicates that the hello.js file is a node.js application 
    to be handled by the iisnode module -->

    <handlers>
      <add name="iisnode" path="hello.js" verb="*" modules="iisnode" />
    </handlers>

    <!-- use URL rewriting to redirect the entire branch of the URL namespace
    to hello.js node.js application; for example, the following URLs will 
    all be handled by hello.js:
    
        http://localhost/node/express/myapp/foo
        http://localhost/node/express/myapp/bar
        
    -->

    <rewrite>
      <rules>
        <rule name="myapp">
          <match url="myapp/*" />
          <action type="Rewrite" url="hello.js" />
        </rule>
      </rules>
    </rewrite> 
    
  </system.webServer>
</configuration>
