Waad/Truffle 🍄

A Laravel package for creating in-memory models using SQLite. Perfect for static data, test fixtures, and high-performance read operations.

Features: Zero configuration • Full Eloquent support • Type safety • Performance optimized

Installation

composer require waad/truffle

Quick Start

<?php

use Illuminate\Database\Eloquent\Model;
use Waad\Truffle\Truffle;

class Product extends Model
{
    use Truffle;

    protected $fillable = ['name', 'price', 'category'];
    
    protected $casts = [
        'price' => 'float',
    ];

    // Define your in-memory data records
    protected $records = [
        ['id' => 1, 'name' => 'Laptop', 'price' => 999.99, 'category' => 'Electronics'],
        ['id' => 2, 'name' => 'Coffee Mug', 'price' => 12.50, 'category' => 'Kitchen'],
    ];
}

// Use standard Eloquent queries
$products = Product::all();
$laptop = Product::where('name', 'Laptop')->first();
$avgPrice = Product::avg('price');

Data Types

Static Data

protected $records = [
    ['id' => 1, 'name' => 'John', 'email' => '[email protected]'],
];

Dynamic Data

public function getRecords()
{
    return collect(range(1, 100))->map(fn($i) => [
        'id' => $i,
        'name' => "User {$i}",
        'email' => "user{$i}@example.com",
    ])->toArray();
}

Schema Definition

use Waad\Truffle\Enums\DataType;

protected $schema = [
    'id' => DataType::Id,
    'name' => DataType::String,
    'email' => DataType::String,
    'age' => DataType::Integer,
    'is_active' => DataType::Boolean,
    'salary' => DataType::Decimal,
    'metadata' => DataType::Json,
    'created_at' => DataType::Timestamp
];

Advanced Usage

Complete Model Configuration

class User extends Model
{
    use Truffle;

    protected $fillable = ['name', 'email', 'age', 'department'];
    
    protected $casts = [
        'age' => 'integer',
        'is_active' => 'boolean',
    ];

    protected $records = [
        ['id' => 1, 'name' => 'Alice', 'email' => '[email protected]', 'age' => 30, 'is_active' => true],
    ];

    protected $schema = [
        'id' => DataType::Id,
        'name' => DataType::String,
        'email' => DataType::String,
        'age' => DataType::Integer,
        'is_active' => DataType::Boolean,
    ];

    // Scopes
    public function scopeActive($query)
    {
        return $query->where('is_active', true);
    }
}

Performance Configuration

protected $insertChunkRecords = 500; // Batch size for large datasets
protected $foreignKeyConstraints = true; // Enable foreign key constraints
protected $prefixDatabaseName = 'my_prefix_'; // Database name prefix

// Migration hook for custom indexes
protected function thenMigration(Blueprint $table)
{
    $table->index('name');
}

Use Cases

Static Reference Data

class Country extends Model
{
    use Truffle;

    public $incrementing = false;
    protected $keyType = 'string';
    protected $primaryKey = 'code';

    protected $records = [
        ['code' => 'US', 'name' => 'United States'],
        ['code' => 'CA', 'name' => 'Canada'],
    ];
}

Configuration Settings

class AppSetting extends Model
{
    use Truffle;

    public $incrementing = false;
    protected $keyType = 'string'; 
    protected $primaryKey = 'key';

    protected $records = [
        ['key' => 'app_name', 'value' => 'My Application'],
        ['key' => 'maintenance_mode', 'value' => 'false'],
    ];

    public static function getValue(string $key, $default = null)
    {
        $setting = static::where('key', $key)->first();
        return $setting ? $setting->value : $default;
    }
}
