Web Browser Game Development
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
- Asset compression - KTX2, Draco, WebP
- Lazy loading - Load on demand
- Object pooling - Avoid GC
- Draw call batching - Reduce state changes
- 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, <2MB | | Gameplay | Stream on demand | | Background | Prefetch next level |
5. PWA for Games
Benefits
- Offline play
- Install to home screen
- Full screen mode
- Push notifications
Requirements
- Service worker for caching
- Web app manifest
- HTTPS
6. Audio Handling
Browser Requirements
- Audio context requires user interaction
- Create AudioContext on first click/tap
- Resume context if suspended
Best Practices
- Use Web Audio API
- Pool audio sources
- Preload common sounds
- Compress with WebM/Opus
7. Anti-Patterns
| ❌ Don't | ✅ Do | |----------|-------| | Load all assets upfront | Progressive loading | | Ignore tab visibility | Pause when hidden | | Block on audio load | Lazy load audio | | Skip compression | Compress everything | | Assume fast connection | Handle slow networks |
Remember: Browser is the most accessible platform. Respect its constraints.

No-code automation democratizes workflow building. Zapier and Make (formerly Integromat) let non-developers automate business processes without writing code. But no-code doesn't mean no-complexity - these platforms have their own patterns, pitfalls, and breaking points. This skill covers when to use which platform, how to build reliable automations, and when to graduate to code-based solutions. Key insight: Zapier optimizes for simplicity and integrations (7000+ apps), Make optimizes for power
