1. Introduction to Angular

• What is Angular? (Framework vs Library, AngularJS vs Angular 2+)

• History of Angular (AngularJS to Angular 16+)

• Features: Two-way data binding, dependency injection, component-based architecture

• Use Cases: Single-Page Applications (SPAs), enterprise apps, dynamic web apps

2. Setting Up Angular

• Prerequisites: Node.js, npm, TypeScript

• Installing Angular CLIgular/cli

• Creating a New Projectpp

• Running the App

3. Angular Architecture

• Modules: @NgModule, root module (AppModule)

• Components: @Component, templates, styles

• Services: @Injectable, dependency injection

• Directives: Structural (*ngIf, *ngFor) and attribute directives

• Routing: RouterModule, RouterOutlet

4. TypeScript Basics

• Why TypeScript? (Static typing, ES6+ features)

• Data Types: string, number, boolean, any, void

• Interfaces: Defining custom types

• Classes: Constructors, methods, inheritance

• Decorators: @Component, @Injectable, @NgModule

5. Angular Components

• Creating a Componentrate component my-component

• Component Lifecycle Hooks:

  • ngOnInit, ngOnChanges, ngOnDestroy

• Template Syntax: Interpolation ({{ }}), property binding ([ ]), event binding (( ))

6. Data Binding

• Interpolation: {{ user.name }}

• Property Binding: [src]="imageUrl"

• Event Binding: (click)="onClick()"

• Two-Way Binding: [(ngModel)]="name" (requires FormsModule)

7. Directives

• Built-in Directives:

  • Structural: *ngIf, *ngFor

  • Attribute: ngClass, ngStyle

• Custom Directives

8. Pipes

• Built-in Pipes: date, uppercase, lowercase, currency, json

• Custom Pipesenerate pipe reverse

9. Services and Dependency Injection

• Creating a Serviceta

• Injecting Servicesa

• Singleton Pattern: Services are singleton by default

10. Angular Modules

• Root Module: AppModule

• Feature Modules: Organizing code into modules

• Lazy Loading: Loading modules on demand

• Shared Modules: Reusable components/directives/pipes

11. Routing and Navigation

• Setting Up Routes

• Router Outlet

• RouterLink

• Route Parameters

12. Forms in Angular

• Template-Driven Forms:

  • FormsModule, ngModel, ngForm

• Reactive Forms:

  • ReactiveFormsModule, FormGroup, FormControl

• Form Validation: Built-in validators, custom validators

13. HTTP Client

• Setting Up HttpClient

• Making HTTP Requests

• Error Handling

14. State Management

• RxJS Basics: Observables, operators (map, filter, switchMap)

• NgRx (Optional): Actions, reducers, store, effects

15. Advanced Topics

• Angular Animations: @angular/animations

• Internationalization (i18n): Translating templates

• Server-Side Rendering (SSR): Angular Universal

• Progressive Web Apps (PWAs): Service workers, offline support

16. Testing in Angular

• Unit Testing: Jasmine + Karma

• End-to-End Testing: Protractor (or Cypress)

17. Deployment

• Building for Production

• Deploying to Platforms:

  • Firebase: firebase init, firebase deploy

  • Netlify: Drag-and-drop dist folder

  • GitHub Pages: angular-cli-ghpages

18. Angular Best Practices

• Folder Structure: Feature-based organization

• Lazy Loading: Optimizing performance

• Change Detection: OnPush strategy

• Code Splitting: Reducing bundle size

19. Final Project Ideas

• E-Commerce App: Product listing, cart, checkout

• Blog Platform: CRUD operations, user authentication

• Weather App: Fetching data from a weather API

20. Modern Angular Features

• Standalone Components (Angular 14+): No NgModule required

• Signals (Angular 16+): Reactive state management

• ESBuild (Angular 16+): Faster builds
