Introduction

Laravel Knight is a powerful helper extension for the Laravel PHP framework, designed to provide a more robust and efficient development experience. It offers enhanced Eloquent models, query builders, controller utilities, caching mechanisms, optimistic locking, middleware collections, and PostgreSQL array support.

Requirements

• PHP 7.4+
• Laravel 6.0+

Features

• Enhanced Eloquent Models: Advanced caching mechanisms, optimistic locking, soft deletes, and convenient data manipulation methods
• Optimized Query Builder: Extended with whereLike, whereRange, primary key caching queries, and more
• PostgreSQL Array Support: Native PostgreSQL array type handling with whereIntArrayContains, whereTextArrayOverlaps, etc.
• Middleware Collection: Authentication, environment guards, IP restrictions, CORS, HSTS, request logging
• Controller Utilities: Action trait with parameter validation, caching, and event dispatching
• OPcache Management: Commands for compiling, clearing, and monitoring OPcache
• Queue Job Tools: Built-in jobs for ping checks, file cleanup, cache GC, and WeChat token refresh
• Mixin Extensions: Extended Collection, Carbon, Str, and Query Builder classes

Installing

composer require hughcube/laravel-knight -vvv

Usage

1. Model Enhancements

Extend HughCube\Laravel\Knight\Database\Eloquent\Model to get caching and other utilities.

<?php

namespace App\Models;

use HughCube\Laravel\Knight\Database\Eloquent\Model;
use Psr\SimpleCache\CacheInterface;
use Illuminate\Support\Facades\Cache;

class User extends Model
{
    public function getCache(): ?CacheInterface
    {
        return Cache::store('redis');
    }
}

// Usage
$user = User::findById(1);              // Fetch with cache
$users = User::findByIds([1, 2, 3]);    // Batch fetch with cache
$user = User::noCacheQuery()->find(1);  // Bypass cache

2. Optimistic Locking

Add optimistic locking to prevent data conflicts in concurrent scenarios.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use HughCube\Laravel\Knight\Database\Eloquent\Traits\OptimisticLock;

class Product extends Model
{
    use OptimisticLock;
}

// Migration: $table->unsignedBigInteger('data_version')->default(1);

// Usage
$product = Product::find(1);
$product->price = 100.50;

try {
    $product->save(); // Auto handles optimistic locking
} catch (\HughCube\Laravel\Knight\Exceptions\OptimisticLockException $e) {
    // Handle conflict
}

// Disable lock temporarily
$product->disableOptimisticLock()->save();

3. Query Builder Extensions

// LIKE queries
Order::query()->whereLike('name', '%keyword%')->get();
Order::query()->whereEscapeLike('name', 'keyword')->get();      // Escaped contains
Order::query()->whereEscapeLeftLike('name', 'prefix')->get();   // Escaped prefix

// Range query
Order::query()->whereRange('created_at', ['2023-01-01', '2023-12-31'])->get();

// Available (not soft-deleted) query
Order::availableQuery()->get();

4. PostgreSQL Array Queries

// Integer array queries
User::query()->whereIntArrayContains('role_ids', [1, 2])->get();
User::query()->whereIntArrayOverlaps('tag_ids', [3, 4])->get();

// Text array queries
Post::query()->whereTextArrayContains('tags', ['php', 'laravel'])->get();

// Array length/empty checks
User::query()->whereArrayLength('permissions', '>', 0)->get();
User::query()->whereArrayIsNotEmpty('roles')->get();

5. Middleware

// routes/web.php
Route::middleware(['knight.only-local'])->group(function () {
    // Local access only
});

Route::middleware(['knight.only-private-ip'])->group(function () {
    // Private IP only
});

Route::middleware(['knight.https'])->group(function () {
    // Force HTTPS
});

Available middleware:

• knight.authenticate - Authentication
• knight.only-local / knight.only-local-env - Local restrictions
• knight.only-prod-env / knight.only-test-env - Environment restrictions
• knight.only-private-ip / knight.only-public-ip - IP restrictions
• knight.https - Force HTTPS
• knight.hsts - HSTS header
• knight.log-request - Request logging
• knight.cors - CORS handling

6. Controller Action Trait

<?php

namespace App\Http\Controllers;

use HughCube\Laravel\Knight\Routing\Controller;

class ProductController extends Controller
{
    public function show(int $id)
    {
        return $this->getOrSet(
            $this->getActionCacheKey(__METHOD__, ['id' => $id]),
            fn() => Product::find($id),
            60
        );
    }
}

7. OPcache Commands

# Compile files to OPcache
php artisan opcache:compile

# Clear CLI OPcache
php artisan opcache:clear-cli

# Create preload script
php artisan opcache:create-preload

8. Built-in Queue Jobs

use HughCube\Laravel\Knight\Queue\Jobs\PingJob;
use HughCube\Laravel\Knight\Queue\Jobs\CleanFilesJob;
use HughCube\Laravel\Knight\Queue\Jobs\CacheTableGcJob;

// Dispatch jobs
PingJob::dispatch();
CleanFilesJob::dispatch('/path/to/clean', '*.log', 7);
CacheTableGcJob::dispatch();

Configuration

Publish the configuration file:

php artisan vendor:publish --provider="HughCube\Laravel\Knight\ServiceProvider"

Configure route prefixes in config/knight.php:

return [
    'opcache' => [
        'route_prefix' => false,  // Set to enable OPcache routes, false to disable
    ],
    'request' => [
        'route_prefix' => false,  // Request log routes
    ],
    'ping' => [
        'route_prefix' => null,   // Ping routes
    ],
    'phpinfo' => [
        'route_prefix' => false,  // PHPInfo routes
    ],
    'devops' => [
        'route_prefix' => false,  // Devops system info routes
    ],
];

Contributing

You can contribute in one of three ways:

1. File bug reports using the issue tracker.
