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 {}

Best Practices

✅ DO

• Follow established patterns and conventions
• Write clean, maintainable code
• Add appropriate documentation
• Test thoroughly before deploying

❌ DON'T

• Skip testing or validation
• Ignore error handling
• Hard-code configuration values
