Laravel Eloquent Spatial

This Laravel package allows you to easily work with spatial data types and functions.

This package supports MySQL v8, MySQL v5.7, and MariaDB v10.

Getting Started

Installing the Package

You can install the package via composer:

composer require matanyadaev/laravel-eloquent-spatial

Setting Up Your First Model

First, generate a new model along with a migration file by running:
```
php artisan make:model {modelName} --migration
```

Next, add some spatial columns to the migration file. For instance, to create a "places" table:

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;

class CreatePlacesTable extends Migration
{
    public function up(): void
    {
        Schema::create('places', static function (Blueprint $table) {
            $table->id();
            $table->string('name')->unique();
            $table->point('location')->nullable();
            $table->polygon('area')->nullable();
            $table->timestamps();
        });
    }

    public function down(): void
    {
        Schema::dropIfExists('places');
    }
}

Run the migration:
```
php artisan migrate
```

In your new model, fill the $fillable and $casts arrays and use the HasSpatial trait:

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use MatanYadaev\EloquentSpatial\Objects\Point;
use MatanYadaev\EloquentSpatial\Objects\Polygon;
use MatanYadaev\EloquentSpatial\Traits\HasSpatial;

/**
 * @property Point $location
 * @property Polygon $area
 */
class Place extends Model
{
    use HasSpatial;

    protected $fillable = [
        'name',
        'location',
        'area',
    ];

    protected $casts = [
        'location' => Point::class,
        'area' => Polygon::class,
    ];
}

Interacting with Spatial Data

After setting up your model, you can now create and access spatial data. Here's an example:

use App\Models\Place;
use MatanYadaev\EloquentSpatial\Objects\Polygon;
use MatanYadaev\EloquentSpatial\Objects\LineString;
use MatanYadaev\EloquentSpatial\Objects\Point;
use MatanYadaev\EloquentSpatial\Enums\Srid;

// Create new records

$londonEye = Place::create([
    'name' => 'London Eye',
    'location' => new Point(51.5032973, -0.1217424),
]);

$whiteHouse = Place::create([
    'name' => 'White House',
    'location' => new Point(38.8976763, -77.0365298, Srid::WGS84->value), // with SRID
]);

$vaticanCity = Place::create([
    'name' => 'Vatican City',
    'area' => new Polygon([
        new LineString([
              new Point(12.455363273620605, 41.90746728266806),
              new Point(12.450309991836548, 41.906636872349075),
              new Point(12.445632219314575, 41.90197359839437),
              new Point(12.447413206100464, 41.90027269624499),
              new Point(12.457906007766724, 41.90000118654431),
              new Point(12.458517551422117, 41.90281205461268),
              new Point(12.457584142684937, 41.903107507989986),
              new Point(12.457734346389769, 41.905918239316286),
              new Point(12.45572805404663, 41.90637337450963),
              new Point(12.455363273620605, 41.90746728266806),
        ]),
    ]),
])

// Access the data

echo $londonEye->location->latitude; // 51.5032973
echo $londonEye->location->longitude; // -0.1217424

echo $whiteHouse->location->srid; // 4326

echo $vacationCity->area->toJson(); // {"type":"Polygon","coordinates":[[[41.90746728266806,12.455363273620605],[41.906636872349075,12.450309991836548],[41.90197359839437,12.445632219314575],[41.90027269624499,12.447413206100464],[41.90000118654431,12.457906007766724],[41.90281205461268,12.458517551422117],[41.903107507989986,12.457584142684937],[41.905918239316286,12.457734346389769],[41.90637337450963,12.45572805404663],[41.90746728266806,12.455363273620605]]]}

Extension

You can add new methods to the Geometry class through macros.

Here's an example of how to register a macro in your service provider's boot method:

class AppServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        Geometry::macro('getName', function (): string {
            /** @var Geometry $this */
            return class_basename($this);
        });
    }
}

Use the method in your code:

$londonEyePoint = new Point(51.5032973, -0.1217424);

echo $londonEyePoint->getName(); // Point

Development

Here are some useful commands for development:

Run tests: composer pest
Run tests with coverage: composer pest-coverage
Perform type checking: composer phpstan
Format your code: composer php-cs-fixer

Before running tests, make sure to run docker-compose up to start the database container.
