Angular Module Design
Table of Contents
Overview
Architect scalable Angular applications using feature modules, lazy loading, services, and RxJS for reactive programming patterns.
When to Use
- Large Angular applications
- Feature-based organization
- Lazy loading optimization
- Dependency injection patterns
- Reactive state management
Quick Start
Minimal working example:
// users.module.ts
import { NgModule } from "@angular/core";
import { CommonModule } from "@angular/common";
import { ReactiveFormsModule } from "@angular/forms";
import { UsersRoutingModule } from "./users-routing.module";
import { UsersListComponent } from "./components/users-list/users-list.component";
import { UserDetailComponent } from "./components/user-detail/user-detail.component";
import { UsersService } from "./services/users.service";
@NgModule({
declarations: [UsersListComponent, UserDetailComponent],
imports: [CommonModule, ReactiveFormsModule, UsersRoutingModule],
providers: [UsersService],
})
export class UsersModule {}
