> Framework selection and browser-specific principles.

1. Framework Selection

Decision Tree

What type of game?
│
├── 2D Game
│   ├── Full game engine features? → Phaser
│   └── Raw rendering power? → PixiJS
│
├── 3D Game
│   ├── Full engine (physics, XR)? → Babylon.js
│   └── Rendering focused? → Three.js
│
└── Hybrid / Canvas
    └── Custom → Raw Canvas/WebGL

Comparison (2025)

| Framework | Type | Best For | |-----------|------|----------| | Phaser 4 | 2D | Full game features | | PixiJS 8 | 2D | Rendering, UI | | Three.js | 3D | Visualizations, lightweight | | Babylon.js 7 | 3D | Full engine, XR |

2. WebGPU Adoption

Browser Support (2025)

| Browser | Support | |---------|---------| | Chrome | ✅ Since v113 | | Edge | ✅ Since v113 | | Firefox | ✅ Since v131 | | Safari | ✅ Since 18.0 | | Total | ~73% global |

Decision

• New projects: Use WebGPU with WebGL fallback
• Legacy support: Start with WebGL
• Feature detection: Check navigator.gpu

3. Performance Principles

Browser Constraints

| Constraint | Strategy | |------------|----------| | No local file access | Asset bundling, CDN | | Tab throttling | Pause when hidden | | Mobile data limits | Compress assets | | Audio autoplay | Require user interaction |

Optimization Priority

1. Asset compression - KTX2, Draco, WebP
2. Lazy loading - Load on demand
3. Object pooling - Avoid GC
4. Draw call batching - Reduce state changes
5. Web Workers - Offload heavy computation

4. Asset Strategy

Compression Formats

| Type | Format | |------|--------| | Textures | KTX2 + Basis Universal | | Audio | WebM/Opus (fallback: MP3) | | 3D Models | glTF + Draco/Meshopt |

Loading Strategy

| Phase | Load | |-------|------| | Startup | Core assets, Remember: Browser is the most accessible platform. Respect its constraints.
