Express Web Server

Main challenge is being clear about where data resides and where its being injected into web page.

• server0 - demo routes f1 and f2
• server1 - get a lucky number
• server2 - /input/:name/:email data moved to server in URL
• server3 - shows routes f1, f2, input etc
• server4 - Form action="/input" method="POST" to move data to server then back again using literal tick mark to inject data dynamically into Web Page
• server5 - Uses public directory for "static" web page called index1.html and "fetch" to move data back to web server route /input which then stores names and redirects back to / route.
• server6 - Uses index2.html to render "dark mode" using bootstrap css.

• Debugging Web Page + Web server needs careful attention. Which one is causing the error?
• Web Page can be debugged using Chrome IDE
• Web Server can be run in debug mode with breakpoints.
• Note: Web page may used "cached" version so may not reflect updates. Do hard refresh (look this up)

Note that README.md is using markdown. To run code

node serverX.js

console.log('Hello, World!');
