Angular and it’s vision for the future.
Angular is a framework for building single-page client applications using HTML and Type Script. It implements core and optional functionality as a set of Type Script libraries that you import into your applications.
Angular is an open-source front-end JavaScript framework used primarily for developing single-page web applications (SPAs) and dynamic web applications.
There are certain fundamental concepts on which the architecture of Angular applications. The basic building blocks of the Angular framework are Angular components that are organized into Ng Modules which collects related code into functional Angular can choose among and modify according to your program logic and data. Components define views , which are sets of screen elements use services, which provide specific functionality not directly related to views. Service providers can be injected into components as dependencies, to make code modular, reusable, and efficient. An Angular application is defined by a set of Ng Modules .
In addition to components and modules, Angular also relies heavily on dependency injection, which allows components and services to be easily injected with the dependencies they require. This promotes modularity and reusability by separating concerns and allowing components and services to be easily tested in isolation. Another key concept in Angular is data binding, which enables synchronization between the model and view. There are several types of data binding in Angular, including interpolation, property binding, event binding, and two-way binding. Angular also provides a robust set of directives, which are used to manipulate the DOM, apply styling, and add dynamic behavior to components. Directives can be either built-in or custom, and they are a powerful tool for creating reusable, declarative code. Finally, Angular provides a comprehensive set of tools for managing application state, including observables, pipes, and the RxJS library. Observables enable asynchronous programming, while pipes provide a convenient way to transform data in templates. Overall, Angular’s architecture is designed to promote modularity, reusability, and efficiency, while providing a rich set of tools for creating complex and dynamic web applications. Angular is a popular JavaScript framework used for developing single-page applications (SPAs) and web applications. The framework is based on a set of fundamental concepts that form the architecture of Angular applications. These concepts include:
  1. Components: Components are the basic building blocks of an Angular application. They define the views of the application and are responsible for rendering the user interface (UI). A component encapsulates the HTML template, the logic that controls the view, and any associated styles.
  2. Modules: Modules are collections of related components, services, and directives that form a functional unit of the application. A module can be used to organize the application into logical blocks and to provide lazy loading of code.
  3. Services: Services are used to provide functionality that is not directly related to the UI. Services can be used for data access, validation, logging, and other tasks. They are typically singleton objects that can be injected into components as dependencies.
  4. Directives: Directives are used to add behavior to the HTML elements in the application. They can be used to create custom HTML tags, modify the behavior of existing tags, or provide reusable UI components.
  5. Templates: Templates define the structure of the views in an Angular application. They are used to bind data to the UI and to define the behavior of the components.
  6. Dependency Injection: Dependency Injection (DI) is a design pattern used in Angular to manage dependencies between objects. It allows for the creation of loosely coupled components, making the code more modular, reusable, and efficient.
  7. Angular application is defined by a set of Ng Modules. These modules are used to organize the code into logical units and to provide lazy loading of code. The modules can be used to manage dependencies between the components and services in the application. Overall, these fundamental concepts form the basis of the architecture of Angular applications, making it a powerful and flexible framework for building modern web applications.
There are certain fundamental concepts on which the architecture of Angular applications depends. The basic building blocks of the Angular framework are Angular components that are organized into Ng Modules which collects related code into functional Angular can choose among and modify according to your program logic and data. Components define views , which are sets of screen elements use services, which provide specific functionality not directly related to views. Service providers can be injected into components as dependencies, to make code modular, reusable, and efficient. An Angular application is defined by a set of Ng Modules . What are the types of Angular? Angular has all the versions which came after Angular JS (Angular 1), Angular 2, Angular 4, Angular 5 and now Angular 6. It has the latest and most refined framework till date to design a web application that is dynamic and responsive. What is good about Angular? Angular offers powerful DI instrument and services to resolve various productivity issues and speed up the development process as efficient problem solving patterns: Dependency Injection (DI) is a design pattern that makes it possible to improve the efficiency and  modularity of an application. Classes, Modules, components and services are that use decorators Decorators are used by modules, components and services These decorators mark their type and provide metadata that tells Angular how to use them. View is defined as the metadata for a component class associates it with a template. A template combines ordinary HTML with Angular directives and binding markup that allow Angular to modify  HTML before rendering it for display. The metadata for a service class provides the information Angular need to make it available to components through dependency injection ( DI). Each of these subjects is introduced in more detail in the following pages. Introduction to Modules. Introduction to Components. Templates and views. Component metadata. Data binding. Directives. Pipes. Introduction to services and dependency injection. Features of Angular: Any app size. Start quickly. You can start small knowing that Angular’s tools support your apps as they grow. … A great community. Community resources. … Build productively. Powerful command-line interface. … For everyone, everywhere. Internationalization tools. Scope of Angular: The scope is the binding part between the HTML (view) and the JavaScript (controller). The scope is an object with the available properties and methods. The scope is available for both the view and the controller. Why use Angular instead of JavaScript? Angular empowers developers to build rich internet applications (RIAs) more easily. Where many JavaScript frameworks focus on expanding the capabilities of JavaScript itself, Angular  instead provides methods for enhancing HTML. Angular expands the capabilities of HTML beyond being a simple markup language Why Angular is called framework? Angular is considered a framework which offers strong opinions how application to be structured and moreover much more functionality out of the box, don’t need to decide routing libraries to use, just start coding. What is difference between React and Angular? Angular is a full-fledged framework, while React is a JavaScript library. Why Angular is a platform? Angular is a development platform, built on Type Script. As a platform, Angular includes: A component-based framework for building scalable web applications. A collection of well-integrated libraries that cover a wide variety of features, including routing, forms management, client-server communication, and more. Businesses are striving for an ultra-effective online presence these days. Hence, the need for a robust web development framework with cutting-edge features is at an all-time high. Angular is a highly popular web development framework that offers rich user experiences, fast responsiveness, and code maintainability. It is one of the most sought-after JavaScript frameworks and is aimed to make front-end development much simpler and accessible.   Angular-React JS-Java script Training by DOCC Kolkata.
