Angular Documentation

Welcome to the Angular documentation page! Below you will find essential information and resources to help you get started with Angular, a popular JavaScript framework for building single-page applications.

Getting Started

Before diving into Angular, it's important to have a basic understanding of JavaScript and TypeScript. Here's a brief overview of what you need to know:

JavaScript: The core language for Angular.
TypeScript: A superset of JavaScript that adds optional static typing.

For more information on JavaScript and TypeScript, check out our JavaScript Resources and TypeScript Resources pages.

Angular CLI

The Angular CLI (Command Line Interface) is a powerful tool for developing Angular applications. It provides a variety of commands to help you create, manage, and build your applications.

To get started with the Angular CLI, follow these steps:

Install Node.js and npm (Node Package Manager).
Install the Angular CLI globally using npm:
```
npm install -g @angular/cli
```
Create a new Angular project:
```
ng new my-angular-project
```
Navigate to your project directory:
```
cd my-angular-project
```

For more detailed instructions on using the Angular CLI, visit the Angular CLI documentation.

Components

Angular applications are built using components. A component is a self-contained, reusable part of an application. Each component has its own template, styles, and logic.

Here's an example of a simple Angular component:

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

@Component({
  selector: 'app-greeting',
  template: `<h1>Welcome to Angular!</h1>`
})
export class GreetingComponent {}

For more information on Angular components, check out the Angular Components documentation.

Directives

Angular directives are used to manipulate the DOM based on specific patterns. They can be used to create reusable patterns for styling, animations, and more.

Here's an example of a simple Angular directive:

import { Directive, HostListener } from '@angular/core';

@Directive({
  selector: '[app-hover]'
})
export class HoverDirective {
  @HostListener('mouseover') onMouseOver() {
    console.log('Mouse is over the element!');
  }

  @HostListener('mouseout') onMouseOut() {
    console.log('Mouse has left the element!');
  }
}

For more information on Angular directives, visit the Angular Directives documentation.

Services

Angular services are used to share data and functionality across components. They can be injected into components and used to perform tasks such as fetching data from a server.

Here's an example of a simple Angular service:

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

@Injectable({
  providedIn: 'root'
})
export class DataService {
  private data = 'Hello, Angular!';

  constructor() { }

  getData() {
    return this.data;
  }
}
