Angular 7 is a platform and framework which is used to create client applications in HTML and TypeScript. Angular 7 is written in TypeScript. Angular 7 implements core and optional functionality as a set of TypeScript libraries which you import in your app. NgModules are the basic building blocks of an Angular 7 application. They provide a compilation context for components. An Angular 7 app is defined by a set of NgModules and NgModules collect related code into functional sets.
Components and services both are simply classes with decorators that mark their types and provide metadata which guide Angular to do things. Every Angular application always has at least one component known as root component that connects a page hierarchy with page DOM. Each component defines a class that contains application data and logic, and is associated with an HTML template that defines a view to be displayed in a target environment.
In Angular 7, developers create a service class for data or logic that isn't associated with a specific view, and they want to share across components.Dependency Injection (DI) is used to make your component classes lean and efficient. DI doesn't fetch data from the server, validate user input, or log directly to the console; it simply renders such tasks to services.In Angular 7, Router is an NgModule which provides a service that facilitates developers to define a navigation path among the different application states and view hierarchies in their app.
