Using Modern Browser APIs

Prefer native browser capabilities over third-party dependencies. Use progressive enhancement with sensible fallbacks.

Core Principles

  • PREFER native APIs over third-party dependencies
  • Use progressive enhancement with fallbacks for unsupported APIs
  • Use async and secure patterns for safe, non-blocking access

Observation & Monitoring

  • Intersection Observer - viewport visibility detection
  • ResizeObserver - element sizing changes
  • PerformanceObserver - performance metrics

Navigation & Transitions

  • View Transitions API - hardware-accelerated state changes
  • URLPattern API - declarative URL matching for routing

Data Access

  • Clipboard Async API - clipboard operations
  • Web Share API - native sharing
  • File System Access API - file operations with permissions

Performance

  • Web Locks API - coordinate resource access
  • Scheduling API - task prioritization
  • Web Workers - offload computation from main thread

Implementation Guidance

Always use feature detection:

js
if ('clipboard' in navigator) { … }
  • Prioritize promise-based APIs
  • Clearly communicate permission requests to users
  • Always provide graceful fallbacks for unsupported browsers
