🔍 Usage

1️⃣ Using the Built-in World Facade (Recommended)

The package now includes a World Facade, making it easier to access data:

use World;

$continents = World::continents()->get();  // Get all continents
$countries = World::countries()->get();  // Get all countries

2️⃣ Manually Instantiate the Class

use TheCoder\World;

$world = new World();

$continents = $world->continents()->get();  
$countries = $world->countries()->get();  

Get Countries by Continent

$asia = World::continents('Asia')->first();

$asia = World::continents()->englishNameEqual('Asia')->first();  

$asiaCountries = World::continents()->englishNameEqual('Asia')->countries()->get();  

Get Provinces & Cities

$iranProvinces = World::countries('Iran')->provinces()->get();

$iranProvinces = World::countries()->englishNameEqual('Iran')->provinces()->get();

$gilanCities = World::provinces('Gilan')->cities()->get();  
  
$gilanCities = World::provinces()->englishNameEqual('Gilan')->cities()->get();

⚡Caching for Maximum Performance

Since the World database is static and never changes, this package supports permanent caching to eliminate redundant database queries and significantly improve performance.

Enable Caching

You can enable caching in the config/world.php file:

  'cache' => [
      'enabled' => true,
      'prefix' => 'thecoder-world-',
      'tag' => 'thecoder-world',
      'ttl' => null, // Store cache forever
  ],

Setting ttl to null ensures that data is cached forever.

Use Cached Data in Queries

If caching is enabled, queries will automatically store results in the cache forever.

Manually Clear Cache (If Needed)

To clear the cache manually, run:

  php artisan cache:clear

Or in code:

World::clearCache();

🏗 Package-Integrated Laravel Facade

The package now provides a World Facade out-of-the-box, meaning Laravel users don't need to set it up manually.

✔ No need to register aliases
✔ Works automatically in Laravel

Just install the package and start using it:

use World;

$continents = World::continents()->get();

---

🧪Testing

Ensure you have the necessary dependencies installed:

composer install --dev

⚠️ Database Configuration for Testing

Due to special columns in the database, SQLite is not supported for testing.

Instead, configure MySQL in phpunit.xml:

    <php>
        <env name="DB_CONNECTION" value="mysql"/>
        <env name="DB_HOST" value="127.0.0.1"/>
        <env name="DB_PORT" value="3306"/>
        <env name="DB_DATABASE" value="world_test_database"/>
        <env name="DB_USERNAME" value="root"/>
        <env name="DB_PASSWORD" value=""/>
    </php>
