Junior Web Developer Exercise

This is the exercise for the Junior Web Developer position at LOGIC. The objective of this exercise is to create a web application.

Spec

This is full functionality of the web application we expect you to create.

Home Page

• This is what appears, when the user first opens the web application
• This page contains a form including a text area and a submit button, and an empty div element.
• When the form is submitted, each line of the text area should be submitted to the /api/sort endpoint (defined below) and when the results are back, the sorted input should be displayed the div element, described above.
• When the form is submitted, the button should be disabled and a loading text should be displayed until the results are back.
• When the results are back, the button should be enabled again, with the original text.

Sorting API endpoint (/api/sort)

• This endpoint should receive and array of strings, sort them and return them back
• The sorting algorithm should be Quicksort (do not use any libraries or built-in functions for sorting)
• The API endpoint should validate that the correct data (array of strings) has been submitted, otherwise it should return a 400 status code

Documentation

There should be brief (just a few words on each case), yet clear documentation of:

• How to run your application
• How each function you wrote works

Example

If the user enters the text below:

banana
apple
orange

The following JSON request should be made:

POST /api/sort

[
    "banana",
    "apple",
    "orange"
]

The following JSON response should be returned:

[
    "apple",
    "banana",
    "orange"
]

And the following text should be displayed when the request completes:

apple
banana
orange
