Installation

You can install the package via Composer:

composer require litepie/repository

The package will automatically register its service provider.

Quick Start

1. Create a Repository

Use the artisan command to generate a repository:

php artisan make:repository UserRepository

This will create a repository class and interface in your app/Repositories directory.

2. Use the Repository

<?php

namespace App\Http\Controllers;

use App\Repositories\Contracts\UserRepositoryInterface;

class UserController extends Controller
{
    public function __construct(
        private UserRepositoryInterface $userRepository
    ) {}

    public function index()
    {
        $users = $this->userRepository->paginate(15);
        return view('users.index', compact('users'));
    }

    public function store(Request $request)
    {
        $user = $this->userRepository->create($request->validated());
        return redirect()->route('users.show', $user);
    }
}

Usage

Basic CRUD Operations

// Create
$user = $userRepository->create(['name' => 'John Doe', 'email' => '[email protected]']);

// Read
$user = $userRepository->find(1);
$users = $userRepository->all();

// Update
$user = $userRepository->update(1, ['name' => 'Jane Doe']);

// Delete
$userRepository->delete(1);

Advanced Querying

// Find with relationships
$user = $userRepository->with(['posts', 'comments'])->find(1);

// Search and filter
$users = $userRepository
    ->where('status', 'active')
    ->orderBy('created_at', 'desc')
    ->paginate(10);

// Custom queries
$users = $userRepository->findWhere([
    ['status', '=', 'active'],
    ['created_at', '>', now()->subDays(30)]
]);

// Advanced filtering
$users = $userRepository
    ->filter(['status' => 'active', 'role' => ['admin', 'moderator']])
    ->search('john', ['name', 'email'])
    ->dateRange('created_at', '2024-01-01', '2024-12-31')
    ->get();

// Request-based filtering
$users = $userRepository
    ->filterFromRequest(request()->all(), ['name', 'email', 'status'])
    ->sortFromRequest(request()->all(), ['name', 'created_at'])
    ->paginate(15);

// Join tables
$posts = $postRepository
    ->select(['posts.*', 'users.name as author_name'])
    ->join('users', 'posts.user_id', '=', 'users.id')
    ->where('posts.status', 'published')
    ->orderBy('posts.created_at', 'desc')
    ->get();

// Complex joins with conditions
$posts = $postRepository
    ->select(['posts.*', 'users.name as author_name'])
    ->selectRaw('COUNT(comments.id) as comments_count')
    ->join('users', 'posts.user_id', '=', 'users.id')
    ->leftJoin('comments', 'posts.id', '=', 'comments.post_id')
    ->where('posts.status', 'published')
    ->groupBy(['posts.id', 'users.name'])
    ->having('comments_count', '>', 5)
    ->orderByRaw('comments_count DESC')
    ->get();

Custom Repository Example

<?php

namespace App\Repositories;

use App\Models\User;
use App\Repositories\Contracts\UserRepositoryInterface;
use Litepie\Repository\BaseRepository;

class UserRepository extends BaseRepository implements UserRepositoryInterface
{
    public function model(): string
    {
        return User::class;
    }

    public function findActiveUsers()
    {
        return $this->where('status', 'active')->get();
    }

    public function findByEmail(string $email)
    {
        return $this->where('email', $email)->first();
    }

    public function getRecentUsers(int $days = 30)
    {
        return $this->where('created_at', '>=', now()->subDays($days))
                   ->orderBy('created_at', 'desc')
                   ->get();
    }
}

Service Provider Bindings

The package automatically binds repository interfaces to their implementations. You can also manually bind repositories in your AppServiceProvider:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use App\Repositories\UserRepository;
use App\Repositories\Contracts\UserRepositoryInterface;

class AppServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->app->bind(UserRepositoryInterface::class, UserRepository::class);
    }
}

🚀 Large Dataset Optimization

When dealing with datasets over 5 million records, traditional pagination becomes slow. This package provides several optimization strategies:

Cursor-Based Pagination (Recommended)

// Much faster than OFFSET pagination for large datasets
$users = $userRepository
    ->where('status', 'active')
    ->cursorPaginate(20);

// For APIs
return response()->json([
    'data' => $users->items(),
    'next_cursor' => $users->nextCursor()?->encode(),
    'has_more' => $users->hasMorePages(),
]);

Fast Pagination (No Total Count)

// Skip expensive COUNT(*) queries
$users = $userRepository
    ->where('status', 'active')
    ->fastPaginate(20);

Smart Pagination (Auto-Optimization)

// Automatically chooses the best pagination method based on dataset size
$users = $userRepository
    ->where('status', 'active')
    ->smartPaginate(20);

Memory-Efficient Processing

// Process large datasets without memory issues
$userRepository->chunk(1000, function ($users) {
    foreach ($users as $user) {
        // Process each user
    }
});

// Or use lazy collections
$users = $userRepository->lazy(1000);
foreach ($users as $user) {
    // Memory-efficient iteration
}

Performance Comparison

Method	1M Records	5M Records	10M Records	Best For
Standard	~500ms	~2000ms	~5000ms+	Small datasets
Fast	~50ms	~100ms	~150ms	No total needed
Cursor	~10ms	~15ms	~20ms	Large datasets
Seek	~5ms	~10ms	~15ms	Real-time feeds

🔍 Query String Filter Parser

Parse complex filter expressions from URL query strings for advanced search and filtering capabilities.

Complex Filter Syntax

// Parse filter string like:
// "category:IN(Apartment,Bungalow);price:BETWEEN(100000,500000);status:EQ(Published);bua:GT(1000)"

$properties = $propertyRepository
    ->parseQueryFilters($filterString, ['category', 'price', 'status', 'bua'])
    ->cursorPaginate(20);

Supported Operators

Comparison: EQ, NEQ, GT, GTE, LT, LTE
Arrays: IN, NOT_IN
Ranges: BETWEEN, NOT_BETWEEN
Strings: LIKE, NOT_LIKE, STARTS_WITH, ENDS_WITH
Nulls: IS_NULL, IS_NOT_NULL
Dates: DATE_EQ, DATE_GT, DATE_BETWEEN, YEAR, MONTH
JSON: JSON_CONTAINS, JSON_LENGTH

Real-World Example

// URL: /api/properties?filters=category:IN(Apartment,Villa);price:BETWEEN(100000,500000);bedrooms:IN(2,3,4)

public function search(Request $request, PropertyRepository $repository)
{
    $filterString = $request->get('filters');
    
    // Security: Define allowed fields
    $allowedFields = ['category', 'price', 'bedrooms', 'status', 'location'];
    
    $properties = $repository
        ->parseQueryFilters($filterString, $allowedFields)
        ->with(['images', 'location'])
        ->optimizedPaginate(20);
        
    return response()->json([
        'data' => $properties->items(),
        'filters' => $repository->getFilterSummary($filterString),
    ]);
}

Frontend Integration

// JavaScript filter builder
const filters = new FilterBuilder()
    .addFilter('category', 'IN', ['Apartment', 'Villa'])
    .addFilter('price', 'BETWEEN', [100000, 500000])
    .build();
// Output: "category:IN(Apartment,Villa);price:BETWEEN(100000,500000)"

fetch(`/api/properties?filters=${encodeURIComponent(filters)}`)
    .then(response => response.json())
    .then(data => console.log(data));
