Practice What You Learned

First Express Homework

Practice the Basics of Express

Learning Objectives

• Set up some express servers for practice
• make some get routes
• use url/query parameters

Prerequisites

• Nodejs
• npm packages
• Introduction to expressjs
• Request/response/ how the internet works basics
• Basic understanding of routing
• JavaScript, HTML fundamentals

Technical Requirements

1. Must be able run without syntax errors (ok if it breaks after the user tries to do something, though do try to comment on the code that isn't working)
2. Must get functionality required for each section working

Learning Objectives

• Practice setting up express applications.
• Practice creating custom routes.
• Practice using parameters from a request.

Take one Down and Pass it Around

Build an express application that enables users to count down the number of bottles of beer. Don't like beer? Pass around bottles of soda, kombucha, or milk etc.

Instructions

• mkdir pass-it-around
• cd pass-it-around
• npm init -y
• build a basic express server

Requirements

• On the home page (get "/"), users should see:

  • "99 Bottles of beer on the wall"
  • a link that says "take one down, pass it around"
  • this should link to /98, where the number represents the number of bottles left.

• When a number is given in the url (get "/:number_of_bottles"), users should see:

  • The number of bottles of beer on the wall (i.e. 98 Bottles of beer on the wall.)
  • a link to "take one down, pass it around", where the href is number of bottles in the parameter minus 1.

• If there are 0 bottles left, do not show a link to "take one down"

  • Add a link to start over, which directs the user back to the home page.

Hints

• You should use an anchor tag with an href to link to the next 'page'

Bonus

• Have some more fun

Update your page to be something like

99 little bugs in the code
99 little bugs
Take on down
Patch it around
127 bugs in the code

Make the bugs go down by one, but then have some sort of functionality where the bug count can randomly go up

You have a lot of freedom to make it work how you want!
