Angular Architecture Summary

summarize this architecture :
  • Anuglar apps contain one or more modules. Every angular application has at least one module which is the root module.
  • Each module contains one or more components and services.A component controls a portion of the view on the browser.
  • Each component contains an HTML template and a class to control the logic for that particular view. The template represents the view in the browser.
  • Module can also have services which contains the business logic of your application.
  • The modules export and import code as when required and finally render the view in the browser.











Component

as a class name                   selector: '.app-test2',             <div class="app-test2"> </div>
as an attribute                     selector: '[app-test3]',           <div app-test3><div>
