🚀 Optimizing Angular Navigation with RouteReuseStrategy

Ever noticed your Angular component reloading every time you navigate back and forth between routes? 🤔

That’s where RouteReuseStrategy comes in.

🔄 What is it? RouteReuseStrategy is a powerful Angular interface that lets you cache and reuse components during routing boosting performance and user experience.

🔧 Use case: Perfect for apps with tabs, dashboards, or lists where reloading data every time is unnecessary.

💡 How it works: You can customize when Angular should store, detach, and reuse a route's

🛠️ By implementing your own strategy, you can:

• Cache components intelligently
• Avoid re-fetching data
• Preserve scroll position or form state

✨ This can make your app feel faster and smoother especially in large or data-heavy projects.

✅ Pros:
Faster Navigation – Components are not recreated, improving performance.
State Retention – Keeps form data or scroll position when returning to a route.
Fewer API Calls – Reduces redundant data fetching on route revisit.

❌ Cons:
Increased Memory Use – Cached components stay in memory.
More Complex Logic – Custom implementation can be tricky.
May Skip Guards/Resolvers – Could lead to outdated or inconsistent data.

✅ Best Practices

✅ Use only for routes that benefit from caching (e.g. dashboards, forms).
🧠 Ensure reused components don’t hold outdated or stale data.
🧹 Manage memory by clearing unused cached routes when needed.
