Updating Your Photo Album App for Routing

The photo album app is quite easy to adapt to express. You have to do only a few things to get it working:

• Create a package.json and install express.

• Replace the http module’s server with that of express.

• Replace the handle_incoming_request function with routing handlers.

• Update the way you get query parameters in express. (They are placed on req.query for your convenience.)

Now copy the last version of the photo app you created at the end of Chapter 6, “Expanding Your Web Server,” to a new folder (you can call it basic_routing/) and place the following package.json inside:

{

"name": "Photo-Sharing",

"description": "Our Photo Sharing Application",

"version": "0.0.2",

"private": true,

"dependencies": {

"async": "0.1.x",

"express": "3.x"

}

}

You can run npm install to make sure express and async are installed to node_modules/. You can then change the top of the server.js file to use express instead of the http module:

var express = require('express');

var app = express();
