    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.

    Hello World Express.js app

    More Information

    Check out Express.js Guide.


    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.


    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.


    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:

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

    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:

        color red

    The index.html file:

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

    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:

        .update(new Date().toDateString().toString() + id)

    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).
