README

Elegant data layer abstraction for Laravel using the Repository Pattern with powerful criteria-based filtering. Keep your controllers clean and your data logic reusable.

Features

• 🏗️ Repository Pattern — Abstract Eloquent models behind clean interfaces
• 🔍 Criteria System — Composable, reusable query filters (where, like, date, JSON, null, in)
• ⚡ Zero Boilerplate — Artisan generators for repositories, services, and criteria
• 🔗 Fluent Chaining — Chain any Eloquent Builder method directly on repositories
• 🔄 Auto Query Reset — Query state resets after execution, preventing stale queries
• 📦 Laravel Auto-Discovery — Install and go, no manual provider registration

Requirements

• PHP 8.1+
• Laravel 9.0+

Installation

composer require bytetcore/serpo

Publish the configuration:

php artisan vendor:publish --tag=serpo-config

Quick Start

1. Generate a Repository

# Basic repository
php artisan make:repository UserRepository

# With a specific model
php artisan make:repository UserRepository --model=User

# With a corresponding service class
php artisan make:repository UserRepository --model=User --service

2. Generate a Service

php artisan make:service UserService

3. Generate a Custom Criteria

php artisan make:criteria ActiveUserCriteria

Usage

Basic Repository

namespace App\Repositories;

use App\Models\User;
use ByteTCore\Serpo\Repositories\BaseRepository;

class UserRepository extends BaseRepository
{
    public function __construct(User $model)
    {
        parent::__construct($model);
    }
}

Query Methods

$repo = app(UserRepository::class);

// Get all records
$users = $repo->all();

// Get with specific columns
$users = $repo->get(['id', 'name', 'email']);

// Get first record
$user = $repo->first();

// Get first or throw exception
$user = $repo->firstOrFail();

// Get latest record
$user = $repo->last();
$user = $repo->last('updated_at');

Eloquent Builder Chaining

All Eloquent Builder methods are available directly on the repository:

$users = $repo->where('active', true)
    ->orderBy('name')
    ->limit(10)
    ->get();

$count = $repo->where('role', 'admin')->count();

$users = $repo->with('posts')->whereHas('posts')->get();

Criteria-Based Filtering

Define reusable filter conditions in your repository:

use ByteTCore\Serpo\Criteria\WhereCriteria;
use ByteTCore\Serpo\Criteria\LikeCriteria;
use ByteTCore\Serpo\Criteria\DateCriteria;
use ByteTCore\Serpo\Constants\Filter;

class UserRepository extends BaseRepository
{
    protected array $conditions = [
        // Simple equality (default operator is '=')
        'status' => WhereCriteria::class,

        // Search across multiple columns
        'keyword' => [
            'class' => LikeCriteria::class,
            'columns' => 'name|email',
            'boolean' => Filter::OR,
            'pattern' => Filter::CONTAINS,
        ],

        // Comparison operators via params
        'min_age' => [
            'class' => WhereCriteria::class,
            'columns' => 'age',
            'operator' => Filter::GTE,
        ],

        // Date filtering
        'created_after' => [
            'class' => DateCriteria::class,
            'columns' => 'created_at',
            'operator' => Filter::GTE,
        ],
    ];

    public function __construct(User $model)
    {
        parent::__construct($model);
    }
}

Apply filters from request data:

// In your controller
$users = $repo->filters($request->only(['status', 'keyword', 'min_age']))->get();

Available Criteria

Detailed Criteria Walkthrough

Database Comparisons

'status' => WhereCriteria::class, // Checks if 'status' matches input
'price_over' => [
    'class' => WhereCriteria::class,
    'columns' => 'price',
    'operator' => Filter::GTE // ->where('price', '>=', input)
]

Search & Text (LikeCriteria)

Automatically supports SQL padding (%) so you don't have to inject % in strings.

'keyword' => [
    'class' => LikeCriteria::class,
    'columns' => 'title|content|author',
    'boolean' => Filter::OR, // ->where('title', 'like', '%val%') OR ->where('content', ...)
    'pattern' => Filter::CONTAINS, // Optional. Other options: STARTS_WITH, ENDS_WITH
]

Ranges (BetweenCriteria)

Expects an array of precisely two values: [$start, $end].

'price_range' => [
    'class' => BetweenCriteria::class,
    'columns' => 'price' // expects $request->price_range = [100, 500]
]

Working with Dates

Filter via specific date, year, or month. Extremely useful for reporting dashboards.

'created_at' => DateCriteria::class, // Date match YYYY-MM-DD
'birth_year' => YearCriteria::class,
'birth_month' => MonthCriteria::class,

Sets & Arrays

Checks whether a column is among an array of inputs.

'tags' => InCriteria::class,    // Expects $request->tags = ['php', 'laravel']
'ignore' => NotInCriteria::class, // Exclude IDs

Nullity Checks

Pass a truthy value (true, 1) to trigger these.

'unverified' => NullCriteria::class,    // ->whereNull('email_verified_at')
'active_only' => NotNullCriteria::class // ->whereNotNull('email_verified_at')

JSON Columns

Filter based on JSON arrays directly in the database.

'has_tag' => JsonContainsCriteria::class, // ->whereJsonContains('tags', input)

Dynamic Sorting (OrderByCriteria)

Pass Filter::ASC or Filter::DESC to dynamically sort records dynamically instead of hardcoding ->orderBy().

'sort_date' => [
    'class' => OrderByCriteria::class,
    'columns' => 'created_at' // expects $request->sort_date = Filter::DESC
]

Custom Criteria

namespace App\Criteria;

use ByteTCore\Serpo\Criteria\BaseCriteria;
use Illuminate\Database\Eloquent\Builder;

class ActiveWithRecentPostsCriteria extends BaseCriteria
{
    public function apply(Builder $query): void
    {
        $query->where('active', true)
            ->whereHas('posts', fn (Builder $q) => $q->where('created_at', '>=', now()->subDays(30)));
    }
}

Auto-Reset Behavior

By default, the query builder resets after each execution to prevent stale state:

$active = $repo->where('active', true)->get();   // query resets after get()
$all = $repo->all();                              // fresh query — returns all records

Disable auto-reset when you need to reuse the query:

$repo->withoutAutoReset()
    ->where('active', true);

$count = $repo->count();       // same filtered query
$users = $repo->get();         // same filtered query

Configuration

// config/serpo.php
return [
    'repository' => [
        'namespace' => env('SERPO_REPOSITORY_NAMESPACE', 'Repositories'),
    ],
    'service' => [
        'namespace' => env('SERPO_SERVICE_NAMESPACE', 'Services'),
    ],
    'criteria' => [
        'namespace' => env('SERPO_CRITERIA_NAMESPACE', 'Criteria'),
    ],
];
