This theme implements a robust Dependency Injection (DI) and Closure-based architecture, offering significant advantages over traditional Full Site Editing (FSE) approaches:
Whilst FSE promotes a block-based paradigm that inherently couples view and model layers, our DI/Closure architecture maintains strict separation of concerns:
- Dependency Management: Proper inversion of control through container-based service resolution
- Testability: Isolated components with clear boundaries and dependencies
- Maintainability: Modular structure allowing for precise modifications without side effects
Unlike FSE's React-based implementation, which:
- Creates additional JavaScript runtime overhead
- Increases DOM tree complexity through nested block structures
- Requires substantial client-side processing for block rendering
Our approach:
- Minimises DOM tree depth through optimised template structures
- Reduces JavaScript payload by leveraging native browser capabilities
- Implements efficient server-side rendering patterns
The theme supports two distinct operational modes:
Production Mode (Default)
- Optimised Tailwind CSS delivery
- Minimal runtime overhead
- Maximum performance optimisation
Development Mode
- Live Tailwind configuration
- Enhanced debugging capabilities
- Direct style modifications
Built with shadcn/ui compatibility in mind:
- Consistent component architecture
- Theme-wide design token system
- Dark mode support out of the box
Achieves perfect Google PageSpeed scores across all metrics:
- Performance: 100/100
- Accessibility: 100/100
- Best Practices: 100/100
These scores are maintained across both Production and Development modes, ensuring optimal performance regardless of operational context.
- Implements PSR-4 compliant autoloading
- Utilises singleton pattern for service management
- Features comprehensive dependency injection container
- Maintains WordPress coding standards whilst introducing modern PHP patterns
This architecture demonstrates that WordPress themes can maintain high performance and clean architecture without compromising on modern development practices or user experience.
