Node.js/Express.js based Interview test

Instructions:

Use Node version 6.9.1 to run these commands.

npm install

npm run serv

Your app will be served at http://localhost:8888

Basically you have to write two solutions for this problem. One using callbacks and second using promises.

  Use callbacks/promises to fetch the titles of these web addresses. Parse them in HTML and return bACK HTML
  Basically you will be fetching home page of each web address, extracting the title tag and display it along with
  original address e.g
  URL: http://localhost:8888/fetch/the/titles?address=google.com&address=http://amazon.com&address=http://www.youtube.com
  Note: this is just example where only three addresses are given, it can be any number.
  You will get input address in array from query params in following two files 
  ./server/titles/callbacks/titles.service.js  
  ./server/titles/promises/titles.service.js
  These services should return following HTML (example) to controllers. Your controllers will then send it back to browser for rendering:

   <ul>
    <li>url: google.com title: <h2>Google</h2></li>
    <li>url: http://amazon.com title: <h2>Amazon.com: Online Shopping for Electronics, Apparel, Computers, Books, DVDs & more</h2></li>
    <li>url: http://www.youtube.com title: <h2>YouTube</h2></li>
   </ul>

Open these two files to find where you will be writing your code.

./server/titles/callbacks/titles.service.js

./server/titles/promises/titles.service.js

Important note

You are highly encouraged to change/add files, and improve architecture of application. We really like modular/compact/self-describing code. Keep in mind the following three golden principles.

1. DRY(Do not repeat yourself)

2. KISS(Keep it Simple Stupid)

3. YAGNI(You "Ain't Gonna Need It)
