Angular Lazy Loading Modules: Complete Guide for Performance
Angular Lazy Loading Modules: Complete Guide for Performance
Why lazy load?
- Reduces initial bundle size significantly
- Faster first contentful paint
- Better user experience on slow networks
How to implement:
1. Create feature modules with their own routing
2. Use loadChildren in your app-routing.module.ts
3. Angular CLI handles code splitting automatically
Example:
const routes: Routes = [
{ path: 'dashboard', loadChildren: () => import('./dashboard/dashboard.module').then(m => m.DashboardModule) }
];
Pro tips:
- Use preloading strategies for critical routes
- Monitor bundle sizes with webpack-bundle-analyzer
- Consider route-level code splitting for large apps
