TL;DR: ExpressWorks is an automated Express.js/Node.js workshop.
During fun times at NodeConf 2013 one of the workshops was stream-adventures by @substack and @maxogden. It’s done in the form of an old text-based console game. Recently, it was metamorphosed into nodeschool.io with the addition of learning resources on LevelDB, Node itself and other topics. The menu and validation framework was abstracted into the workshopper library.
Inspired by all these resources, I put together ExpressWorks during our 36 hour hackathon at DocuSign. You can visit npmjs.org/expressworks or github.com/azat-co/expressworks. While for those who have Node.js (and NPM) installed already, this simple command will do the trick:
$ sudo npm install -g expressworks@latest
In case you have any suggestions or found bugs (I’m sure there are some!), submit GitHub issues at github.com/azat-co/expressworks/issues.
Here is the list of exercises as of now (they’ll be more later!).
Create an Express.js app that runs on localhost:3000, and outputs “Hello World!” when somebody goes to root ‘/home’.
process.argv 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 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>
Style your HTML from previous example with some Stylus middleware. The path to main.styl file is provided in
process.argv 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
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.
Write a server that reads a file (file name is passed in
process.argv), parses it to JSON and outputs the content to the user with

…so that you can just access variables needed on the Client, via CodeCompletion on the ServerSide. :) Coding without remembering VariableNames,just hit ctrl+space done.
This would be much more fun.
