Angular is a framework for web development, based on TypeScript. It provides two-way data binding and improved performance for web pages. It also features a semantic versioning system for consistent delivery of new versions.
Angular uses a component-based architecture. Each component defines an HTML template and a class that contains application data. The controller and view components communicate data through a scope. The component template contains binding markup and HTML tags. It also uses pipes to transform values for display.
The application structure is based on a root module and NgModules. The root module connects the component hierarchy with the DOM. NgModules are used to declare compilation contexts for a set of components. These modules also allow users to add services to the application.
Each component is a small piece of user interface that is written in TypeScript. The Angular framework modifies HTML before rendering. This allows the application to respond to user input. Angular also provides out-of-the-box solutions for routing within the application and server communication.
Data binding allows the dynamic behavior of web pages. In most cases, model and view components communicate through a service class. The service class is always associated with a @Injectable decorator.
The Angular framework also allows users to create their own components. Typical applications consist of a root module, NgModules and feature modules. Each component contains an HTML template, a TypeScript class and an CSS selector.
Angular uses an improved hierarchical dependency injection system. This makes it easy to build big applications. The framework is also supported by Google. The company plans to keep developing the technology and hold the lead position in front-end engineering tools.
