Angular Basics
Angular is a platform and framework for building single-page client applications using HTML and TypeScript. Angular is written in TypeScript. It implements core and optional functionality as a set of TypeScript libraries that you import into your apps.
Module
The angular app has its own modularity system called the Angular Module of NgModule . Every Angular app has at least one module known as root module.
Component
The component is a controller class that encapsulates the view and the logic. The component class interacts with the view using the built-in API’s.
Template
The component’s view can be defined by templates. Templates are HTML’s that controls how things should be structured on the screen.
Metadata
Metadata is data about data. In Angular, metadata informs the Angular run time on how to process a class. The class case is the @Component decorator which identifies the class immediately below it as the component class.
Directives
A Directive is a class with @Directive decorator. So, technically a component is a directive with a template. There are two types of directives. Structural and Attribute directive.
Data Binding
Data binding binds the template and its component with the required data. So, we have interpolation, property binding, event binding and two-way binding (ngModel directive)
Services
Services are JavaScript functions designed to do specific tasks. It is a class that can perform certain activities like logging, data service, caching, configuration, etc. There is no service base class but it is one of the fundamental aspects of Angular Apps.
Dependency Injection
DI is a way to supply the instance of a class with fully form dependencies to other class/components. It’s one of the core features which keeps your angular apps loosely coupled.
