Study Notes

Course Overview

The course covers Angular, a modern web application platform that allows developers to build large, robust applications.
The course is divided into five sections: Introduction, Getting Started, Structure and Angular CLI, Advanced Angular Concepts, and Building your first Angular app.

What is Angular?

Angular is a modern web application platform that provides developers with a comprehensive set of tools and capabilities to build large, robust applications.
The core value proposition of Angular is to make it possible to build applications that work for nearly any platform, whether mobile, web, or desktop.

Why Angular?

Building web applications that meet user needs is not a trivial task due to increasing quality and complexity, and user expectations.
Angular helps developers deliver applications that meet these demands, with thousands of internal customers inside Google and external contributions shaping its future.

Getting Started with Angular

Installing Angular and Node
Creating an Angular project

Structure and Angular CLI

The Angular CLI (Command Line Interface) is a powerful tool that helps create, manage, and build Angular projects with ease.
Angular CLI provides code generation capabilities for components, services, modules, and other Angular artifacts.
Angular CLI can also generate modules to organize applications into cohesive, reusable blocks of functionality.

Angular CLI Capabilities

ng new my-app: creates a new Angular application with a basic project structure
ng generate component my-component: generates a new Angular component with necessary files
ng generate module module-name: creates a new module to organize the application
ng generate service service-name: creates a class that can be injected into other components or services
ng generate interface my-interface: defines the shape of data returned from APIs or inputs and outputs of components and services
ng generate class my-class: creates a TypeScript file with the specified class name and a corresponding spec file for testing
ng serve: starts the development server and runs the Angular application locally
ng build: builds a production-ready version of an Angular application
