Basics of Web Development

• HTML: Basic structure of web pages.
• CSS: Styling for presentation and formatting.
• JavaScript: Controls behavior of web applications.

Introduction to Frameworks

• JavaScript Frameworks: Pre-written libraries for common programming tasks.
• Popular Frameworks: React, Angular, Node.js.

Angular Overview

• AngularJS vs Angular:
  • AngularJS (Angular 1.x): JavaScript framework.
  • Angular (2+): TypeScript-based framework with components and improved features.

Versions of Angular

• First Version: AngularJS (2010)
• Latest Version: Angular 12
• Statistics: Second most used technology in libraries & frameworks.

Angular Features

• Component-Based Framework:
  Components are the fundamental building blocks.
• Dependency Injection: Core concept for managing dependencies and enhancing modularity.
• Routing and Navigation: Facilitates single-page applications with multiple views.
• Forms: Efficient handling of user input and CRUD operations.
• Styling: Integration with Bootstrap for responsive designs.

Angular CLI

• What is Angular CLI?
  Command line interface for generating Angular applications quickly.
• Installing Angular CLI:
  • Use the command: npm install -g @angular/cli

Creating a New Project

• Command:
  ng new <project-name>
• Serving the Application:
  ng serve

Angular Components

• Definition:
  Components define views and control the UI.
• Structure: Each component consists of TypeScript, HTML, and CSS files.
• Creating Components:
  Use the command ng generate component <component-name>.

Angular Templates

• Purpose:
  Templates define the UI for Angular components.
• Types of Templates:
  • Inline
  • Template URL

Data Binding in Angular

• Types:
  1. One-way Data Binding
  2. Two-way Data Binding
• One-way Binding:
  Data flows from the model to the view.
• Two-way Binding:
  Data flows between model and view.

Directives in Angular

• What are Directives?
  Functions executed when the DOM is compiled.
• Types of Directives:
  • Component Directives
  • Structural Directives (e.g., *ngIf, *ngFor)
  • Attribute Directives

Dependency Injection in Angular

• Definition:
  Design pattern that allows the injection of dependencies into components.
• Advantages:
  • Improved modularity and testability.

Routing in Angular

• Purpose:
  Enables navigation between different views or components.
• Setting Up Routing:
  Define routes in the app-routing.module.ts file.

Forms in Angular

• Types:
  • Reactive Forms
  • Template-Driven Forms
• Validation:
  Angular provides built-in validators and the ability to create custom validators.

Styling with Bootstrap

• Integrating Bootstrap:
  Use CDN or npm for adding Bootstrap to Angular.
• Creating Responsive Designs:
  Use Bootstrap's grid system and pre-defined classes.

Angular Projects

• Developing an Application:
  • Create components, services, and integrate routing.
  • Use Bootstrap for styling.
• Deploying Applications:
  • Use Docker for containerization.

Interview Preparation

• Common Questions:
  • Explain the architecture of Angular.
  • What is the difference between AngularJS and Angular?
  • How to implement routing in Angular?
  • What are services and how to create them?
• Resources:
  • Edureka's Angular certification course.
  • Angular documentation.
  • Online communities for Angular developers.
