# CLAUDE.md

3+
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
4+
5+
## Repository Overview
6+
7+
PivotPHP Core is a high-performance PHP microframework inspired by Express.js, designed for building APIs and web applications. Current version: 1.1.0 (High-Performance Edition).
8+
9+
## Essential Commands
10+
11+

39+
./scripts/release.sh # Create release after preparation
40+
```
41+
42+
### Running Examples
43+
```bash
44+
composer examples:basic # Basic framework usage
45+
composer examples:auth # Authentication example
46+
composer examples:middleware # Middleware example
47+
```
48+
49+
### v1.1.0 High-Performance Features
50+
```php
51+
// Enable high-performance mode
52+
use PivotPHP\Core\Performance\HighPerformanceMode;
53+
HighPerformanceMode::enable(HighPerformanceMode::PROFILE_HIGH);
54+
55+
// Console commands for monitoring
56+
php bin/console pool:stats # Real-time pool monitoring
57+
```
58+
59+
## Code Architecture
60+
61+
### Core Framework Structure
62+
- **Service Provider Pattern**: All major components are registered via service providers in `src/Providers/`
63+
- **PSR Standards**: Strict PSR-7 (HTTP messages), PSR-15 (middleware), PSR-12 (coding style) compliance
64+
- **Container**: Dependency injection container at the heart of the framework (`src/Core/Container.php`)
65+
- **Event-Driven**: Event dispatcher with hooks system for extensibility
66+
67+
### Key Components
68+
1. **Application Core** (`src/Core/Application.php`): Main application class that bootstraps the framework
69+
- Version constant: `Application::VERSION`
70+
- Middleware aliases mapping for v1.1.0 features
71+
72+
2. **Router** (`src/Routing/Router.php`): High-performance routing with middleware support
73+
- Supports regex constraints: `/users/:id<\d+>`
74+
- Predefined shortcuts: `slug`, `uuid`, `date`, etc.
75+
76+
3. **Middleware Pipeline** (`src/Middleware/`): PSR-15 compliant middleware system
77+
- v1.1.0 additions: LoadShedder, CircuitBreaker
78+
79+
4. **HTTP Layer** (`src/Http/`): PSR-7 hybrid implementation
80+
- Express.js style API with PSR-7 compliance
81+
- Object pooling via `Psr7Pool` and `OptimizedHttpFactory`
82+
83+
5. **v1.1.0 Performance Components**:
84+
- `DynamicPool`: Auto-scaling object pools
85+
- `MemoryManager`: Adaptive memory management
86+
- `PerformanceMonitor`: Real-time metrics
87+
- `DistributedPoolManager`: Multi-instance coordination
88+
89+
### Request/Response Hybrid Design
90+
The framework uses a hybrid approach for PSR-7 compatibility:
91+
- `Request` class implements `ServerRequestInterface` while maintaining Express.js methods
92+
- Legacy `getBody()` renamed to `getBodyAsStdClass()` for backward compatibility
93+
- PSR-7 objects are lazy-loaded for performance
94+
95+
### Testing Approach
96+
- Tests organized by domain in `tests/` directory
97+
- Each major component has its own test suite
98+
- Integration tests verify component interaction
99+
- Use PHPUnit assertions and follow existing test patterns
100+
- v1.1.0 tests in `tests/Integration/V11ComponentsTest.php` and `tests/Stress/`
101+
102+
### Code Style Requirements
103+
- PHP 8.1+ features are used throughout
104+
- Strict typing is enforced
105+
- PHPStan Level 9 must pass
106+
- PSR-12 coding standard via PHP_CodeSniffer
107+
- All new code must include proper type declarations
108+
109+
### Performance Considerations
110+
- Framework optimized for high throughput (2.57M ops/sec for CORS)
111+
- v1.1.0 achieves 25x faster Request/Response creation with pooling
112+
- Benchmark any performance-critical changes using `composer benchmark`
113+
- Avoid unnecessary object creation in hot paths
114+
- Use lazy loading for optional dependencies
115+
116+
## Development Workflow
117+
118+
1. Before committing, run `./scripts/pre-commit` or `./scripts/validate_all.sh`
119+
2. All tests must pass before pushing changes
120+
3. Static analysis must pass at Level 9
121+
4. Code style must comply with PSR-12
122+
5. For releases, use `./scripts/prepare_release.sh` followed by `./scripts/release.sh`
123+
124+
## Current Version Status
125+
126+
- **Current Version**: 1.1.0 (High-Performance Edition)
127+
- **Previous Stable**: 1.0.1 (PSR-7 Hybrid Support)
128+
- **Tests Status**: 315/332 passing (95% success rate)
129+
- **New Features**: High-performance mode, dynamic pooling, circuit breaker, load shedding
130+
131+
## Important Notes
132+
133+
- The framework prioritizes performance, security, and developer experience
134+
- All HTTP components are PSR-7/PSR-15 compliant
135+
- Service providers are the primary extension mechanism
136+
- The event system allows for deep customization without modifying core code
137+
- Documentation updates should be made in the `/docs` directory when adding features
138+
- v1.1.0 features are opt-in and don't affect default behavior
