Angular Lazy Loading: Improve Performance with Route-Based Modules
Introduction
Angular applications become faster through lazy loading since the system loads modules merely when required and consequently decreases the initial bundle dimensions. The performance along with user experience increases due to this implementation.
Why Use Lazy Loading?
✅ Faster Initial Load – Reduces the app's startup time.
✅ Better Performance – Uses memory and bandwidth efficiently.
✅ Improved Scalability – Keeps the code modular and maintainable.
Users experience enhanced UX because the application loads essential features based on the current navigation.
Generate a Feature Module
ng generate module dashboard --route dashboard --module app.moduleConfigure Lazy Loading in app-routing.module.ts
const routes: Routes = [{ path: 'dashboard', loadChildren: () => import('./dashboard/dashboard.module').then(m => m.DashboardModule) }];Optimize with Preloading (Optional)
imports: [RouterModule.forRoot(routes, { preloadingStrategy: PreloadAllModules })]Conclusion
Good application speed and reduced memory usage result from implementing lazy loading techniques which support scalability.
