Drone Challenge

Introduction

Bigdatr has an aerial drone which it uses to take photographs of billboards. Instructions are sent to the drone in a simple language that tells the drone which direction to move and when to take a photo. Moves are always exactly 1 km to the north (^), south (v), east (>) or west (<) or take a photograph (x).

Unfortunately the instruction processor is not perfect yet so the drone may photograph the same billboard multiple times.

For example:

• x^xv takes photos of 2 unique billboards and ends up back at the starting location
• x^^x>>xvvx<<x takes photos of 4 unique billboards, however the first billboard has 2 photos of it since the drone comes back to the starting position
• xx takes 2 photos of the same billboard and does not move

Setting up the project

Fork or download this project, then:

# install dependencies
yarn install

# Run the api
yarn watch:api

The api will start running at http://localhost:4001.

It consists of 2 GET endpoints

1. /instruct-drone - accepts a list of instructions for the drone, and returns all bilboards found with their details. Example usage: http://localhost:4001/instruct-drone?instructions=x^xv

2. /get-billboard - accepts an ID of a billboard and returns details of a single billboard. Example usage: localhost:4001/get-billboard?id=5aba7bffddc4ecbbb81e7fad

Requirements

For this code challenge, you are required to setup and create a simple React app:

• add a way to send drone instructions via a UI to the /instruct-drone endpoint, and display its results
• add a way to retrieve and display billboard details via the UI by using the /get-billboard endpoint.
• you are NOT expected to modify the API - only to build a frontend with React
• please allocate 2 - 3 hours for this challenge
• please add clear instructions on how to run the React app
• please note down improvements in your instructions you would like to implement, or a list of things that need to be done to productionise this app
