Welcome to the Angular tutorial! This guide will help you get started with Angular, a popular JavaScript framework for building dynamic web applications.

Overview

Angular is a robust framework that allows developers to build single-page applications (SPAs) with ease. It provides a wide range of features, including two-way data binding, modular architecture, and dependency injection.

Getting Started

Before you begin, make sure you have Node.js and npm installed on your machine. You can download Node.js from here.

Once you have Node.js and npm installed, you can create a new Angular project by running the following command in your terminal:

ng new my-angular-app

This will create a new directory called my-angular-app with all the necessary files and configurations for your Angular project.

Project Structure

Here's a basic overview of the project structure:

my-angular-app/
├── src/
│   ├── app/
│   │   ├── components/
│   │   │   └── my-component/
│   │   │       ├── my-component.component.html
│   │   │       ├── my-component.component.ts
│   │   │       └── my-component.component.css
│   │   ├── app.module.ts
│   │   ├── app.routing.ts
│   │   └── app.component.html
│   ├── assets/
│   ├── environments/
│   ├── index.html
│   ├── main.ts
│   ├── polyfills.ts
│   ├── styles.css
│   └── tsconfig.json
├── .angular-cli.json
├── .editorconfig
├── .gitignore
├── package.json
└── tsconfig.app.json

Components

Angular applications are composed of components. A component is a self-contained, reusable part of the application. Each component has its own template, style, and script.

For example, let's create a simple component called MyComponent:

ng generate component my-component

This will create a new directory called my-component inside the src/app/components directory. Inside this directory, you will find three files:

  • my-component.component.html: This file contains the HTML template for the component.
  • my-component.component.ts: This file contains the TypeScript code for the component.
  • my-component.component.css: This file contains the CSS styles for the component.

You can now edit these files to create your own custom component.

Two-Way Data Binding

Angular provides two-way data binding, which allows you to easily update the UI when the data changes, and vice versa.

Here's an example of how to use two-way data binding in a component:

<!-- my-component.component.html -->
<input [(ngModel)]="myInput" placeholder="Type something...">
<p>{{ myInput }}</p>

// my-component.component.ts
import { Component } from '@angular/core';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent {
  myInput: string = '';
}

In this example, the ngModel directive is used to create a two-way data binding between the input field and the myInput property of the component.
