🔥 Angular Mistakes That Slow Down Your App (Most Developers Ignore #3) Many Angular apps become slow not because Angular is bad… But because of avoidable mistakes developers make every day. 👇 🚫 1. Too Many API Calls Calling APIs repeatedly without caching or request optimization. 🚫 2. Missing trackBy in ngFor Without trackBy, Angular re-renders the full list unnecessarily. 🚫 3. Heavy Logic Inside Templates Calling functions directly in HTML can trigger execution on every change detection cycle. 🚫 4. No Lazy Loading Loading all modules upfront increases initial load time. 🚫 5. Ignoring OnPush Change Detection Default strategy works, but OnPush can dramatically improve performance. 🚫 6. Memory Leaks from Subscriptions Forgetting to unsubscribe from Observables causes hidden issues over time. 🚫 7. Large Shared Modules Everywhere Importing everything everywhere creates bloated bundles. 💡 High-performing Angular apps are not built by chance. They’re built by developers who understand performance deeply. 👉 Which mistake have you seen most often in real projects? #Angular #WebDevelopment #Frontend #JavaScript #TypeScript #Performance #SoftwareEngineering
