Architecture Of Angular

 Architecture Of Angular

The architecture of an Angular project can vary depending on the size and complexity of the project,

but it typically follows a modular structure.

Modules: Angular applications are composed of several modules, each with a specific purpose. The root module,

 named AppModule, is the starting point of the application and defines the components, services, and other parts

 of the application that are required. Additional modules can be created to organize the code and provide a clear 

structure for the application.

Components: 

============

Components are the building blocks of an Angular application and define the view and behavior of a 

specific part of the application. A component is composed of a template, a class, and metadata that defines the component's behavior.

Services: 

=========

Services provide a way to share data and logic across multiple components in an Angular application. Services 

can be used to encapsulate complex business logic or to interact with APIs to retrieve and manipulate data.

Routing: 

=========

Angular provides a powerful routing system that allows you to define the routes for your application and navigate 

between different parts of the application. Routing is configured in a module and is used to map URLs to components.

Templates: 

==========

Templates define the structure and layout of a component's view and can include HTML, CSS, and Angular template 

expressions and directives.

Data Binding: 

=============

Angular provides a two-way data binding mechanism that allows you to bind data from the component's class to 

the template and vice versa. This makes it easy to keep the view in sync with the data model.

Directives:

===========

 Directives are special attributes that can be added to HTML elements to modify their behavior. Angular provides 

a number of built-in directives, such as ngIf, ngFor, and ngStyle, and it is also possible to create custom directives.

This is a high-level overview of the typical architecture of an Angular project. The specific architecture of an Angular 

project will depend on the requirements of the project and the design decisions made by the development team.

==========================================================================================================

In an Angular project, each file serves a specific purpose and contains different parts of the application:

index.html: 

===========

This is the main HTML file of the application and serves as the entry point for the application.

 It includes the Angular script files and defines the root component of the application.

main.ts: 

=========

This file is the main entry point for the Angular application and sets up the environment for the 

application to run. It bootstraps the root module, AppModule, and starts the application.

app.module.ts: 

==============

This file defines the root module of the application, AppModule, and declares the components, 

services, and other parts of the application that are required.

app.component.ts: 

===================

This file defines the root component of the application, AppComponent, and specifies the 

template and logic for the component.

component.ts: 

================

Components are the building blocks of an Angular application and define the view and behavior 

of a specific part of the application. Each component is defined in its own file, such as ComponentName.component.ts.

service.ts: 

=============

Services provide a way to share data and logic across multiple components in an Angular application.

 Each service is defined in its own file, such as ServiceName.service.ts.

routing.module.ts: 

===================

This file defines the routing configuration for the application and maps URLs to components.

template.html:

================

 Templates define the structure and layout of a component's view and can include HTML, CSS, and Angular 

template expressions and directives. Each component has its own template file, such as ComponentName.component.html.

styles.css: 

=================

This file defines the styles for the components in the application.

This is a general overview of the different types of files that are used in an Angular project. The specific files 

used in a project will depend on the requirements of the project and the design decisions made by the development team.

Angular Dependencies

====================

Angular is a JavaScript framework for building web applications and it has several dependencies

 that are required for it to work properly. These dependencies can be broadly classified into two categories:

Core Dependencies:

Zone.js:

=========

 A JavaScript library for executing code with a specific set of rules and keeping track of its execution in a specific context.

RxJS:

======

 A reactive programming library for managing asynchronous data streams in Angular.

TypeScript:

===========

 A statically typed superset of JavaScript that is used to write Angular applications.

TSLint:

=======

 A linter for the TypeScript language that helps enforce coding conventions.

Additional Dependencies:

Angular Material:

===================

 A library of pre-built UI components that follow Material Design guidelines.

HammerJS: 

============

A library for adding touch gestures (e.g., swipe, pinch, rotate) to web applications.

Browser animations: 

====================

A library for adding animations to Angular applications.

Protractor: 

===========

An end-to-end testing framework for Angular applications.

Karma: 

==========

A test runner for JavaScript applications that can run unit tests in a browser or in a headless environment.

These are some of the commonly used dependencies in Angular applications. The specific dependencies required for an 

Angular project will depend on the features and functionality needed in the application.
