Angular Full Course - Learn Angular In 3 Hours | Angular Tutorial For Beginners | Simplilearn

Introduction

This tutorial provides a comprehensive guide to learning Angular, a popular JavaScript framework used for building single-page applications. Whether you're a beginner or looking to enhance your skills, this step-by-step approach will help you grasp the fundamental concepts and features of Angular.

Step 1: Understand Angular

• Angular is a front-end framework developed by Google.
• It allows developers to create dynamic web applications.
• Key features include two-way data binding, dependency injection, and modular architecture.

Step 2: Explore Angular Architecture

• Angular architecture is based on components and services.
• Components are the building blocks of any Angular application.
• Services are used for sharing data and functionalities across components.

Step 3: Learn Advantages and Limitations of Angular

Advantages

• Strong community support and resources.
• Enhanced performance with Ahead-of-Time (AOT) compilation.
• Built-in support for routing and forms.

Limitations

• Steeper learning curve compared to some other frameworks.
• Can be overkill for small projects.

Step 4: Set Up Your Angular Environment

• Install Node.js and npm (Node Package Manager).
• Install Angular CLI globally by running:

  npm install -g @angular/cli
  

• Create a new Angular project:

  ng new my-angular-app
  

• Navigate to your project directory:

  cd my-angular-app
  

• Start the development server:

  ng serve
  

Step 5: Create Your First Angular Component

• Generate a new component:

  ng generate component my-component
  

• Modify the component's TypeScript file (my-component.component.ts) to include:

  import { Component } from '@angular/core';
  
  @Component({
    selector: 'app-my-component',
    templateUrl: './my-component.component.html',
    styleUrls: ['./my-component.component.css']
  })
  export class MyComponent {
    title = 'Hello, Angular!';
  }
  

• Update the HTML file (my-component.component.html) to display the title:

  <h1>{{ title }}</h1>
  

Step 6: Utilize Dependency Injection

• Dependency injection (DI) is a design pattern used to enhance modularity and flexibility.
• Define a service:

  ng generate service my-service
  

• Inject the service into a component or another service to use its methods.

Step 7: Work with Angular Forms

• Angular supports two types of forms: Template-driven and Reactive forms.
• For template-driven forms, use the FormsModule:

  import { FormsModule } from '@angular/forms';
  

• For reactive forms, use the ReactiveFormsModule:

  import { ReactiveFormsModule } from '@angular/forms';
  

Step 8: Implement Routing

• Set up the Angular router to navigate between different components.
• Configure routes in your application’s main module (app-routing.module.ts):

  const routes: Routes = [
    { path: '', component: HomeComponent },
    { path: 'about', component: AboutComponent }
  ];
  

• Use the <router-outlet> directive in your main HTML file to load the routed components.

Step 9: Bootstrap Angular with External Libraries

• To use Bootstrap in your Angular application:
  • Install Bootstrap via npm:

    npm install bootstrap
    

  • Import Bootstrap CSS in your styles.css or angular.json file.

Step 10: Keep Learning and Practicing

• Regularly explore new features released in Angular versions.
• Join community forums, participate in discussions, and work on projects to enhance your skills.

Conclusion

In this tutorial, you have learned the foundational concepts of Angular, including its architecture, component creation, dependency injection, forms, and routing. By setting up your Angular environment and practicing these steps, you'll be well on your way to becoming proficient in Angular development. Continue exploring more advanced topics and consider building projects to solidify your knowledge.
