README

HackerRank Code Checker API. Extremely simple REST API. Supports more than a dozen languages. All powered by reliable HackerRank servers. You can use your own scoring system or build your own online judge.

40+ programming languages support.

Installation

Themevel is a Laravel package so you can install it via Composer. Run this command in your terminal from your project directory:

composer require shipu/hackerrank-api

Wait for a while, Composer will automatically install Themevel in your project.

Laravel Configuration

When the download is complete, you have to call this package service in config/app.php config file. To do that, add this line in app.php in providers array:

Shipu\HackerRank\HackerRankServiceProvider::class,

To use facade you have to add this line in app.php to the aliases array:

'HackerRank' => Shipu\HackerRank\Facades\HackerRank::class,

Now run this command in your terminal to publish this package resources:

php artisan vendor:publish --provider="Shipu\HackerRank\HackerRankServiceProvider"

after publishing your config file then open config/hackerrank.php and add your hackerrank app key:

return [
    /*
    |--------------------------------------------------------------------------
    | HackerRank API KEY
    |--------------------------------------------------------------------------
    |
    | https://www.hackerrank.com/api/
    |
    */

    'api_key' => env('HACKERRANK_API_KEY', 'YOUR_HACKER_RANK_API_KEY'),
];

also you can add api key in .env :

 HACKERRANK_API_KEY = YOUR_HACKER_RANK_API_KEY

Thats it.
