Angular › NgModules & Modular Architecture

What is a feature module, and how does it help organize a larger Angular application?

Intermediate

Answer

A feature module groups together everything related to one specific area of functionality, such as an orders feature or a user settings feature, keeping that area's components, services, and routing logically separated from unrelated parts of the app, making the overall codebase easier to navigate and maintain.

@NgModule({
  declarations: [OrderListComponent, OrderDetailComponent],
  imports: [CommonModule, RouterModule.forChild(orderRoutes)]
})
export class OrdersModule {}

Real-world example A large e commerce application organizes all order related components and routing logic into a dedicated OrdersModule, making it clear at a glance exactly which files belong to that specific feature area.

Common follow-ups: How does a feature module differ from simply organizing files into folders without an actual NgModule?;How would this same organizational goal be achieved using standalone components instead?
