Server

• The node server listens for get requests at /api/count and uses routes/count.js to handle it.

• The .txt file is requested using the request module, split and converted into an array of words.

• Each word is mapped to its count/frequency i.e a (key,value) pair dictionary is generated.

• N is retrieved from the request parameters and the first n words are sent back.

Client

• Angular based client has a single AppComponent which sends a request to get words with their frequencies by sending N as a parameter.

• Retrieved data is displayed in a table.

• Karma-Jasmine is used for basic unit testing.
