RxJS Skill

Best Practices

1. Observable Creation

• Use appropriate creation operators (of, from, interval, etc.)
• Prefer cold observables for most use cases
• Use subjects sparingly and with clear intent
• Document whether an observable is hot or cold

2. Subscription Management

• Always unsubscribe to prevent memory leaks
• Use takeUntil pattern with destroy$ subject
• Prefer async pipe in templates (auto-unsubscribes)
• Use takeWhile or first for self-completing observables
