Laravel Compatibility Roadmap

Overview

This document outlines our path to Laravel API compatibility while maintaining backward compatibility with existing code. It provides a comprehensive view of package dependencies, implementation status, and migration strategy.

Package Dependency Hierarchy

Level 0: Core Foundation

graph TD
    Container[Container] --> Contracts[Contracts]
    Support[Support] --> Container
    Pipeline[Pipeline] --> Container

Core Dependencies:

• Container: Service container, dependency injection
• Contracts: Interfaces and contracts
• Support: Helper functions, utilities
• Pipeline: Pipeline pattern implementation

Level 1: Infrastructure

graph TD
    Events[Events] --> Container
    Events --> Support
    Config[Config] --> Container
    Config --> Support
    FileSystem[FileSystem] --> Support
    FileSystem --> Container

Infrastructure Dependencies:

• Events: Event dispatching system
• Config: Configuration management
• FileSystem: File system abstraction

Level 2: Core Services

graph TD
    Cache[Cache] --> Events
    Cache --> Container
    Database[Database] --> Events
    Database --> Container
    Queue[Queue] --> Events
    Queue --> Container
    Queue --> Pipeline

Core Service Dependencies:

• Cache: Caching system
• Database: Database abstraction
• Queue: Queue system and job processing

Level 3: HTTP Layer

graph TD
    Routing[Routing] --> Pipeline
    Routing --> Container
    Http[Http] --> Pipeline
    Http --> Events
    Session[Session] --> Cache
    Session --> Events

HTTP Layer Dependencies:

• Routing: Route registration and matching
• Http: HTTP request/response handling
• Session: Session management

Current Implementation Status

Success Metrics

1. API Compatibility

Required:
- 100% Laravel interface implementation
- All Laravel patterns supported
- Full feature parity
- Backward compatibility maintained

2. Performance

Targets:
- Resolution: < 0.1ms per operation
- Memory: < 10MB overhead
- Cache hit rate: > 90%
- Startup time: < 100ms

3. Code Quality

Requirements:
- 100% test coverage
- Static analysis passing
- Documentation complete
- Examples provided

4. Integration

Verification:
- Cross-package tests passing
- Performance benchmarks met
- Real-world examples working
- Migration guides verified

Key Design Decisions

1. Backward Compatibility

// Maintain existing APIs
class Container {
  // Existing methods stay the same
  T make<T>();
  void bind<T>(T instance);
  
  // New methods add functionality
  ContextualBindingBuilder when(Type concrete);
  void tag(List<Type> types, String tag);
}

2. Laravel Compatibility

// Match Laravel's patterns
container.when(UserController)
        .needs<Service>()
        .give((c) => SpecialService());

container.tag([ServiceA, ServiceB], 'services');

container.call(instance, 'method', parameters);

3. Performance Focus

// Add caching
class Container {
  final ResolutionCache _cache;
  final ReflectionCache _reflectionCache;
  
  T make<T>([dynamic context]) {
    return _cache.get<T>(context) ?? _resolve<T>(context);
  }
}

Implementation Strategy

[Previous implementation strategy section remains the same]

Integration Considerations

1. Service Provider Pattern

• Registration phase
• Boot phase
• Deferred providers

2. Event System

• Synchronous events
• Queued events
• Event subscribers

3. Queue System

• Multiple drivers
• Job handling
• Failed jobs

4. Database Layer

• Query builder
• Schema builder
• Migrations

5. HTTP Layer

• Middleware
• Controllers
• Resources

6. Authentication

• Guards
• Providers
• Policies

Getting Started

1. Development Environment

# Clone repository
git clone https://github.com/org/platform.git

# Install dependencies
dart pub get

# Run tests
dart test

2. Package Development

1. Choose package level:
   - Level 0: Foundation packages
   - Level 1: Infrastructure packages
   - Level 2: Core services
   - Level 3: HTTP layer

2. Review dependencies:
   - Check required packages
   - Verify integration points
   - Plan implementation

3. Follow implementation order:
   - Core functionality
   - Laravel compatibility
   - Tests and documentation

3. Quality Assurance

1. Testing:
   - Unit tests
   - Integration tests
   - Performance tests
   - Compatibility tests

2. Documentation:
   - API documentation
   - Usage examples
   - Integration guides
   - Migration guides

3. Performance:
   - Benchmarking
   - Profiling
   - Optimization
