Patient Prism Interview Exercise
Introduction
The masterminds at CalcTek have decided to revolutionize the calculator industry by building an API driven calculator. Genius! They've tasked you with developing the project.
Requirements
Build an API that supports four types of calculation operators:
- Addition
- Subtraction
- Division
- Multiplication
Every calculation should be stored for historical reference.
A calculator interface should be created (Vue.js) that allows the user enter their calculation and receive a response.
A "ticker tape" interface should be built that shows all previous calculations with the ability to delete an individual calculation or clear all previous calculations.
Stretch Goal
To really impress the customers of CalcTek, your calculator should support more complex calculation chains and even additional calculation operators:
sqrt((((9*9)/12)+(13-4))*2)^2)
Pre-requisites
- PHP ^8.0.
- A MySQL database connection with username and passwords
- Copy the .env.example file and rename it as .env.
- Fill the values of the database connection into the .env file.
- Yarn or NPM installed globally.
Installation requirements
- Install required packages.
composer install
- Generate key for application.
php artisan key:generate
- Execute db migrations.
php artisan migrate:install
- Install NPM packages.
yarn install
or
npm install
- Generate the front-end files for prod env.
yarn prod
or
npm run prod
- Generate the front-end files for dev env.
yarn dev
or
npm run dev
- Generate the front-end files for dev env with autoloading.
yarn watch
or
npm run watch
Tests
You can run the tests suit with the next commands:
php artisan test
or
vendor/bin/phpunit
You can specify if the tests should run in parallel with x processes as there are available CPU cores on your machine where x is an integer number.
php artisan test --parallel --process=x
For static analysis
php composer larastan
TODO:
- Add Front-end tests using Laravel Dusk.
- Add the feature of the Stretch Goal section.
