Approach: Let us create an Angular project and install PrimeNG UI module. Then we will create a UI that will showcase Angular PrimeNG Properties of p-button.

Creating Angular Project and Installing Module:

Step 1: To create a angular app, you need to install angular command line interface through npm command.

npm install -g angular-cli

Step 2: Now we will create a angular project.

ng new project_name

Step 3: After creating your react project, move into the folder to perform different operations.

cd project_name

Step 4: After creating the Angular application, Install the required module using the following command:

npm install primeng --save
npm install primeicons --save

Project Structure: After running the commands mentioned in the above steps, if you open the project in an editor, you can see a similar project structure as shown below. The new component user makes or the code changes, we will be performing will be done in the source folder.

Project Structure

Step to Run Application: Run the application using the following command from the root directory of the project:

ng serve --open

Example 1: We are creating a UI that shows above mentioned Properties of p-Button.

• app.component.html

HTML

<div style="margin:100px; text-align: center;">
    <h1 style="color: green;">
