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