How do you lazy load modules in Angular?

Short answer: Lazy loading delays loading feature modules until the user navigates to their route. Implemented with the router using loadChildren and dynamic imports.

Example code

const routes: Routes = [ { path: 'admin', loadChildren: () => import('./admin/admin.module').then(m => m.AdminModule) } ]; This reduces initial bundle size and improves app startup time.

Real-world example (ShopNest)

ShopNest admin can be built in Angular with modules/components, services for API calls, and reactive forms for product edit.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
