How does Angular work

Question

can u resolve my doubt via an example of how Angular work?

Answer 1

Angular is a TypeScript-based front-end framework for building single-page applications (SPAs). It follows the Model-View-Controller (MVC) and Component-Based Architecture.

Key Working Mechanism:

Bootstrapping

The index.html file loads main.ts, which bootstraps the root module (AppModule).

AppComponent is the main component that renders the UI.

Components & Templates

Angular apps are built using components (TypeScript + HTML + CSS).

Components interact using decorators (@Component) and data binding.

Data Binding & Directives

Uses one-way ({{ }}, [property], (event)) and two-way binding ([(ngModel)]).

Directives (*ngFor, *ngIf) manipulate the DOM dynamically.

Dependency Injection (DI)

Services and components are injected using Angular’s DI system to manage state and logic efficiently.

Routing

RouterModule enables navigation without page reloads, improving performance in SPAs.

Change Detection

Uses Zone.js and a Virtual DOM to track changes and update the UI efficiently.
