## Best Practices

### ✅ DO

- Set up source maps for production
- Configure appropriate sample rates
- Track releases and deployments
- Filter sensitive information
- Add meaningful context to errors
- Use breadcrumbs for debugging
- Set user information
- Review error patterns regularly

### ❌ DON'T

- Send 100% of errors in production
- Include passwords in context
- Ignore configuration for environment
- Skip source map uploads
- Log personally identifiable information
- Use without proper filtering
- Disable tracking in production
