Angular continues to evolve, introducing innovative ways to simplify and enhance the developer experience. One of the latest improvements is the introduction of standalone components, which represent a fundamental shift in how we build Angular applications.

What are Angular Standalone Components?

Standalone components are self-contained Angular components that do not require a separate NgModule. They can directly declare dependencies like other components, directives, and pipes, significantly simplifying your application structure.

Benefits of Standalone Components

  • Simplified Project Structure: Reduces the complexity and boilerplate code related to modules.
  • Easier Maintenance: Fewer files and less overhead make components easier to manage and understand.
  • Improved Lazy Loading: Easier and more granular lazy loading of components improves application performance.

Creating a Standalone Component

Here's a simple example of how to define a standalone component:

import { Component } from '@angular/core';

@Component({
  selector: 'app-hello-world',
  template: `Hello, World!`,
  standalone: true
})
export class HelloWorldComponent {}

Importing Other Dependencies

Standalone components can directly import dependencies without the need for modules:

import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';

@Component({
  selector: 'app-user-list',
  standalone: true,
  imports: [CommonModule],
  template: `
    
      {{ user }}
    
  `
})
export class UserListComponent {
  users = ['Alice', 'Bob', 'Charlie'];
}

Lazy Loading Standalone Components

You can easily lazy-load standalone components to improve application performance:

const routes: Routes = [
  {
    path: 'lazy',
    loadComponent: () => import('./lazy.component').then(m => m.LazyComponent)
  }
];

When Should You Use Standalone Components?

  • Ideal for new Angular projects to keep structure lightweight and simple.
  • Great for gradually migrating existing projects from module-based architecture.
  • Suitable for building reusable and self-contained components.

Final Thoughts

Standalone components represent a significant improvement in how Angular developers build applications, promoting simplicity and modularity.
