Express.js workshop based on workshopper and inspired by stream-adventure by @substack and @maxogden. ExpressWorks will provide you with tasks and hints. You write the solutions to these problems. Then, after you wrote a solution as an Express.js app, ExpressWorks will verify your solution to the problem.

Check out Express.js Guide.
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.
Create an Express.js app with a home page (/home) rendered by jade template engine, that shows current date (toDateString).
Write a route ('/form') that processes HTML form input (
) and prints backwards the str value.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 your 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>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 redThe 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>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')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.
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).
