Angular tips I’ve learned in my 2 years as a Frontend Developer 🚀 Still learning every day, but these small practices helped me write cleaner and faster Angular code. 🔹 Tip #1: Use trackBy in *ngFor I learned this while working with large lists—Angular re-renders less and feels much faster. 👉 Small change, big performance boost. 🔹 Tip #2: Prefer async pipe over manual subscriptions Earlier, I used to subscribe everywhere. Now I let Angular handle it. 👉 Cleaner code + fewer memory leaks. 🔹 Tip #3: Keep business logic out of components Move API calls and logic to services. 👉 Components stay readable and easy to maintain. 🔹 Tip #4: Use OnPush when performance matters Especially useful in reusable or shared components. 👉 Better performance with minimal effort. 🔹 Tip #5: ng-container helps keep the DOM clean No unnecessary divs, just better structure. 🔹 Tip #6: Always unsubscribe (unless using async pipe) Unsubscribed observables caused me bugs early in my career. 👉 Lesson learned the hard way 😅 🔹 Tip #7: Lazy load feature modules Helps reduce initial load time in real-world apps. #Angular #FrontendDeveloper #WebDevelopment #SoftwareEngineering #LearningInPublic
Totally agree 💯 Concepts like change detection, lazy loading, and interceptors are very important in large Angular projects.

Great!
Really relatable post These are the exact lessons most of us learn after facing performance issues in real projects. The shift from manual subscriptions to the async pipe is such a game changer—cleaner code and peace of mind Also love the reminder about keeping business logic out of components. Makes long-term maintenance so much easier.
