Trality Animal Challenge

Welcome to the Trality Animal Challenge! You've been contacted by a passionate biology professor to help him out prototying a voting tool for her students. The goal is simple: she wants to determine favourite animals of her students and gather some statistics in the process. Your goal is to take this repository and finish her initial setup.

Setup

Run

yarn start

in the root folder, then

cd challenge && yarn install && yarn start

in the challenge folder.

Goal

You're not allowed to install additional packages related to state management (e.g. Redux, Mobx, etc.) except those already included in package.json and challenge/package.json.

Individual Goals include:

• Continents, areas and animal votes should be aggregated and their votes displayed correctly (no negative votes allowed)
• The statistics section should show a correct aggregate over all continents, areas and animals
• The Download Statistics button should trigger a JSON-download of the current votes in the format of animals.json
• The Reset Statistics button should reset all votes to the values in animals.json
• All votes should persist after refreshing the browser (same browser only)
• Optional Bonus Goal: Votes synchronise across different browser tabs
• Optional Bonus Goal: Adapt the pages' style similar to www.trality.com. Feel free to use any styling or animation library, package or framework.
• Optional Bonus Goal: Add Jest-based unit tests for the component adaptations you've made.

Deliverable

Your deliverable is animal-challenge.zip. E-mail it to [email protected]. The zip-file should include the updated folders and files of this git repository minus .git, .dist and node_modules folders. In addition to achievement of goals, we will evaluate coding style, suitable usage of React in general and your implementation of state handling.
