Installation

The first step in learning Angular 12 is to install it on your machine. To install Angular 12, you will need to have Node.js installed on your machine. You can download Node.js from the official website at https://nodejs.org.

Once you have Node.js installed, open your command prompt or terminal and run the following command to install the Angular CLI:

npm install -g @angular/cli

Once the installation is complete, you can verify that the Angular CLI is installed correctly by running the following command:

ng version

This should display the version of Angular CLI that you have installed.

Creating a New Angular 12 Project

Once you have installed the Angular CLI, you can use it to create a new Angular 12 project. To create a new project, open your command prompt or terminal and run the following command:

ng new my-angular-project

This will create a new Angular 12 project in a directory named "my-angular-project".

Components

Components are the building blocks of an Angular 12 application. A component is a self-contained block of code that defines the behavior of a part of the user interface. Each component can have its own styles, templates, and data.

To create a new component, run the following command:

ng generate component my-component

This will create a new component named "my-component" in your project's "src/app" directory.

Services

Services are used to share data and functionality across components in an Angular 12 application. A service is a class that can be injected into other components, making it easy to reuse code and data.

To create a new service, run the following command:

ng generate service my-service

This will create a new service named "my-service" in your project's "src/app" directory.

Routing

Routing is used to navigate between different pages or views in an Angular 12 application. To set up routing in your Angular 12 project, you will need to create a new module and add routes to it.

To create a new module, run the following command:

ng generate module my-module --route my-route

This will create a new module named "my-module" and add a route to it named "my-route".

Conclusion

Angular 12 is a powerful JavaScript framework that can help you build dynamic and high-performance web applications. In this tutorial, we covered everything you need to know to get started with Angular 12, including installation, creating a new project, components, services, and routing.

With this PDF document and step-by-step instructions, you have all the tools you need to start building your own Angular 12 applications. Good luck!
