Performance Notes
Vector-based animations are lightweight compared to video/GIF
Large or complex animations may require optimization
Reduce unnecessary layers in AE export
Use looping sparingly for mobile performance
Lazy load animations for faster page loads
Security Notes
JSON files are safe, no runtime code execution
Cross-origin loading may require proper CORS headers
No access to sensitive data by default
Safe for embedding in web and mobile apps
Avoid untrusted JSON sources to prevent unexpected behavior
Monitoring Analytics
Check animation load times and frame rate
Track user interaction with animations
Log failed animation loads
Measure memory impact on mobile devices
Benchmark complex animations across devices
Code Quality
Validate JSON exports from AE/Bodymovin
Use wrappers for consistent API usage
Minimize hard-coded values for reusability
Document animation triggers and dynamic properties
Test on all supported platforms
