    Learn Express.js from the author of one of the best books on Express.js—Pro Express.js—workshop to teach you basics of Express.js.

    This workshop is 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.

    Installation (Recommended)

    Recommended global installation:

    $ npm install -g expressworks
    $ expressworks

    If you see errors, try:

    $ sudo npm install -g expressworks
    $ expressworks

    Local Installation (Advanced)

    Run & install locally:

    $ mkdir node_modules
    $ npm install expressworks
    cd node_modules/expressworks
    $ node expressworks

    Optional step that gives your the global command (expressworks) in the Terminal/command prompt:

    $ npm link
    $ expressworks


    $ expressworks

    Note: ExpressWorks depends on a local copy of Express being available in your project folder. To do the exercises, make sure to install the Express.js with

    $ npm init
    $ npm install express@4.11.2

    See Offline Setup for more required dependencies.

    ExpressWorks understands these commands:

        Show a menu to interactively select a workshop.
      expressworks list
        Show a newline-separated list of all the workshops.
      expressworks select NAME
        Select a workshop.
      expressworks current
        Show the currently selected workshop.
      expressworks run program.js
        Run your program against the selected input.
      expressworks verify program.js
        Verify your program against the expected output.

    Offline Setup

    If you would like to setup all node packages beforehand, you can complete this workshop offline. Here are all the modules to install with exact versions that this workshop supports:

    $ npm install express@4.11.2
    $ npm install jade@1.9.2
    $ npm install body-parser@1.12.0
    $ npm install stylus@0.50.0

    Note: You need to have node_modules or packagen.json in your project folder before installing dependencies. Run $ mkdir node_modules or $ npm init to create one of them.


    If you want to reset the list of completed tasks, clean the ~/.config/expressworks/completed.json file.

    Hello World Express.js app

    More Information

    Check out Express.js Guide, Pro Express.js and FREE Express.js cheatsheet.


    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).


    npm i expressworks@3.2.3
