Angular is a free, open-source framework for frontend used for making single-page web application which is based on typescript. Getting started with an Angular application is quite easy and quick.

Step 1 : Install Angular CLI (command line interface) by simply running in your terminal / power shell.

Step 2 : Create your Angular Project, as shown below.

** Install required Angular packages and other functional
dependencies, this might take couple of minutes. **

Step 3 : To run and develop your application locally run the following commands:

Angular Components are the building blocks of an Angular Application. While working on an Angular Application we build or develop our app in bunch of components and attach them with parent (app component) which is responsible for rendering angular application. Each component consists of the following things:
1) Html file
2) Styling File
3) Typescript File
4) Spec File

Standalone Component
Released in Angular 14 and made stable in Angular 15, you can delete all your module. Modules in angular is a great concept (in theory) and it helps angular a lot in reducing the bundle size as different parts of your app get loaded. But overtime as your app grows you need to add more modules and eventually if you want to add or remove dependencies it is hard to tell which dependencies you put there to support which components, making the module difficult to read, maintain leading a mess.

With standalone components you can define / add all your dependencies right on your components itself, all you have to do is to define { standalone: true } on your @Component( ) and let the magic happen for you.

[ In case, if you already have an angular app no worries you can still apply these changes and slowly remove these things from your app.modules.ts until they are empty and deletable ] .

If ever got stuck in switching your angular app to standalone component, this Angular doc is highly recommended [https:// angular.io/guide/standalone-components] for shifting to the latest version of Angular.
