Learn basics of angular. Angular is a popular open-source web application framework developed by Google. It is used for building dynamic single-page applications (SPAs) and is based on TypeScript, a superset of JavaScript.

7 important key features of Angular framework:

  1. Components: Angular follows a component-based architecture where the application is divided into reusable and independent components. Each component consists of a template, which defines the structure and layout of the component, and a class, which contains the logic and data associated with the component.
  2. Directives: Angular provides directives that allow you to extend HTML with additional functionalities and create reusable UI components. Directives can be used to manipulate the DOM, add or remove elements, apply styles dynamically, and more.
  3. Modules: An Angular application is divided into modules, which help in organizing the codebase. Modules encapsulate related components, directives, services, and other artifacts. The root module, known as the AppModule, is the entry point of the application.
  4. Templates and Data Binding: Angular uses a declarative approach for building UIs. Templates in Angular are written in HTML with additional syntax and directives. Data binding allows you to establish a connection between the data in the component class and the template, enabling automatic updates and synchronization.
  5. Services: Services are used to provide shared functionality across components. They are responsible for implementing business logic, fetching data from APIs, and performing other operations. Services can be injected into components using Angular’s dependency injection system.
  6. Routing: Angular provides a built-in router that enables navigation between different views and components in a single-page application. It allows you to define routes, associate them with components, and handle navigation events.
  7. Dependency Injection: Angular’s dependency injection (DI) system helps manage the dependencies of an application. It allows you to declare dependencies in a component’s constructor, and Angular takes care of creating and injecting the instances of those dependencies.

Angular has a large and active community, with extensive documentation and a wide range of third-party libraries and tools available. It is widely used in the development of complex web applications and has features that support scalability, testability, and maintainability.

Some additional Key features about the Angular framework:

  1. TypeScript: Angular is built with TypeScript, a statically-typed superset of JavaScript. TypeScript adds static typing, classes, interfaces, and other features to JavaScript, making it more robust and maintainable. The use of TypeScript in Angular helps catch errors early during development and provides better tooling support.
  2. Reactive Extensions (RxJS): Angular leverages RxJS, a library for reactive programming, to handle asynchronous operations, event handling, and data streams. RxJS provides powerful operators for managing and transforming streams of data, making it easier to handle complex async operations in Angular applications.
  3. Angular CLI: The Angular Command Line Interface (CLI) is a powerful tool that helps with scaffolding, building, and managing Angular projects. It provides a set of commands to generate components, services, modules, and other artifacts, as well as tools for building, testing, and deploying Angular applications.
  4. Angular Universal: Angular Universal is a server-side rendering (SSR) solution provided by Angular. It allows you to render Angular applications on the server, delivering pre-rendered HTML to the client for faster initial page loads and improved SEO.
  5. Angular Forms: Angular provides an advanced forms module for handling user input and form validation. The Angular Forms module offers features like two-way data binding, form controls, form groups, form validation, and form submission handling.
  6. Angular Material: Angular Material is a UI component library that provides pre-designed and reusable UI components following the Material Design guidelines. It offers a wide range of components such as buttons, cards, dialog boxes, menus, sliders, and more, helping developers create consistent and visually appealing user interfaces.
  7. Angular DevTools: Angular has its own set of developer tools called Angular DevTools. These tools integrate with browser developer tools (Chrome and Firefox) and provide additional features specific to Angular development, such as inspecting the component tree, debugging change detection, and profiling performance.
  8. Testing: Angular has excellent support for testing. It provides tools like TestBed and Jasmine for writing unit tests, as well as end-to-end testing capabilities with Protractor. Angular encourages writing tests to ensure the reliability and maintainability of applications.
  9. Mobile Development: Angular offers options for building mobile applications. You can use frameworks like Ionic, which is built on top of Angular, to develop hybrid mobile apps that run on both iOS and Android platforms. Alternatively, you can use NativeScript to build native mobile apps using Angular for the UI layer.
  10. Continuous Integration and Deployment: Angular applications can easily be integrated into a CI/CD (Continuous Integration/Continuous Deployment) pipeline. Various tools like Jenkins, Travis CI, and GitLab CI/CD can be used to automate the build, testing, and deployment processes for Angular applications.

These are just some of the many features and aspects of the Angular framework. Angular continues to evolve, and the Angular team regularly releases updates and improvements to the framework, ensuring its relevance and effectiveness for building modern web applications.
