Angular Basics

Angular is a powerful framework developed by Google for enterprise-level web applications.

1. Philosophy of Angular​

  • Full-featured: Routing, form management, HTTP communication, etc., are all included within the framework.
  • TypeScript-based: Designed from the ground up with TypeScript, ensuring high stability in large-scale projects.
  • Dependency Injection (DI): A robust DI system that reduces code coupling and facilitates testing.

2. Component Example​

In Angular, HTML, CSS, and TypeScript code can be written separately or together.

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

@Component({
  selector: 'app-root',
  standalone: true,
  template: `
    <h1>Hello from {{ name }}!</h1>
    <button (click)="clickMe()">Click Me</button>
  `
})
export class AppComponent {
  name = 'Angular';
  
  clickMe() {
    alert('Nice to meet you!');
  }
}

3. RxJS and Asynchronous Streams​

Angular deeply utilizes the RxJS library to manage data flows as streams, allowing for the declarative processing of complex asynchronous logic.

4. Features of Angular​

  • Two-way Data Binding: Automatic data synchronization between the model and the view.
  • Powerful CLI: Excellent command-line tools for project creation, building, testing, and more.

If you are working on a large-scale collaborative project or need an application with a structured architecture, consider using Angular.
