Steps

Hello World

Create an Express.js app that runs on localhost:3000, and outputs "Hello World!" when somebody goes to root '/home'.

process.argv[2] will be provided by expressworks to you, this is the port number.

Jade

Create an Express.js app with a home page (/home) rendered by jade template engine, that shows current date (toDateString).

Good Old Form

Write a route ('/form') that processes HTML form input (

) and prints backwards the str value.

Static

Apply static middleware to server index.html file without any routes. The index.html file is provided and usable via process.argv[3] value of the path to it. However, you can use you're own file with this content:

  <html>
    <head>
      <link rel="stylesheet" type="text/css" href="/main.css"/>
    </head>
    <body>
      <p>I am red!</p>
    </body>
  </html>

Stylish CSS

Style your HTML from previous example with some Stylus middleware. The path to main.styl file is provided in process.argv[3] or you can create your own file/folder from these:

  p
    color red

The index.html file:

  <html>
    <head>
      <title>expressworks</title>
      <link rel="stylesheet" type="text/css" href="/main.css"/>
    </head>
    <body>
      <p>I am red!</p>
    </body>
  </html>

Param Pam Pam

Create an Express.js server that processes PUT /message/:id requests, e.g., PUT /message/526aa677a8ceb64569c9d4fb.

As the response of this request return id SHA1 hashed with a date:

  require('crypto')
    .createHash('sha1')
    .update(new Date().toDateString().toString() + id)
    .digest('hex')

What's in Query

Write a route that extracts data from query string in the GET /search URL route, e.g., ?results=recent&include_tabs=true, and then transforms outputs it back to the user in JSON format.

JSON Me

Write a server that reads a file (file name is passed in process.argv[3]), parses it to JSON and outputs the content to the user with res.json(object).
