In this article how to create components in angular 16. Here, we will learn about how to use angular components. With the introduction of Angular 16, I am thrilled to explore the latest features and enhancements that make building web applications even more seamless. Components play a pivotal role in Angular development, encapsulating logic, presentation, and behavior.

In Angular 16, creating components is a fundamental skill for building powerful web applications. This step-by-step guide will walk you through the process of creating components in Angular 16. Explore the latest techniques, features, and best practices that will help you build dynamic and interactive components for your web projects.

What are Angular Components?

Angular components are the building blocks of an Angular application. They encapsulate the logic, presentation, and behavior of a specific part of the user interface (UI). A component in Angular consists of a TypeScript class, an HTML template, and optional CSS styles.

The TypeScript class is responsible for defining the component's properties, methods, and event handlers. It interacts with the template and handles user interactions or data manipulation. The component class is decorated with the @Component decorator, which provides metadata about the component, such as its selector, template URL, and style URL(s).

The HTML template defines the structure and layout of the component's UI. It contains HTML markup and can include Angular-specific syntax, such as data bindings, directives, and event bindings. The template receives data from the component's properties and displays it to the user.


The CSS styles (optional) define the visual appearance of the component. You can use inline styles within the component's template or separate CSS files specific to the component.

In this article, I will take you on a step-by-step journey of creating components in Angular 16, leveraging the advancements to enhance your development workflow.

  1. Understanding Components in Angular: Before diving into component creation, let's establish a solid understanding of the concept. I will explain the significance of components in Angular applications, their structure, and their interactions with other parts of the framework.

  2. Setting up an Angular 16 Project: To get started with component creation, we need to set up an Angular 16 project. I will guide you through the installation process, including Node.js installation, Angular CLI setup, and creating a new Angular project using CLI commands.

  3. Generating Components: Angular CLI provides powerful tools for generating components. I will demonstrate how to use the CLI command to create a new component, specifying the component name, selector, template, and styles. Additionally, I'll cover optional configurations like inline templates and styles.

  4. Understanding Component Lifecycle Hooks: Angular offers a set of lifecycle hooks that allow you to respond to specific events during a component's lifecycle. I will introduce the available lifecycle hooks and explain how they can be utilized to perform actions at different stages of a component's existence.

  5. Templating and Data Binding: Harnessing Angular's robust templating and data binding capabilities is key to creating dynamic and interactive components. I will delve into property binding, event binding, and two-way binding, and explore template syntax and structural directives like ngIf and ngFor.

  6. Component Communication: Components often require communication with each other. I will explore different strategies for component communication, including input and output properties, event emitters, and the use of services to share data and functionality between components.

  7. Styling Components: Aesthetically pleasing components can elevate the user experience. I will discuss various approaches to styling components in Angular 16, including inline styles, component-specific stylesheets, and utilizing CSS frameworks.

  8. Unit Testing Components: Ensuring the reliability and functionality of components is crucial. I will introduce you to unit testing in Angular and demonstrate how to write tests for your components using tools like Jasmine and Karma. We'll cover best practices and techniques for validating component behavior.

  9. Component Reusability and Modularity: Discover the art of creating reusable and modular components, empowering you to leverage them across your application. I will explore techniques such as creating component libraries, utilizing Angular modules, and harnessing the power of Angular's dependency injection system.

Here's a code example showcasing the process of creating components in Angular 16:

Step 1: Create a new Angular 16 project using Angular CLI

To start, you'll need to set up a new Angular 16 project. Use the Angular CLI command ng new followed by the name of your project (my-angular-app in this example). Then, navigate to the project directory using cd my-angular-app.

ng new my-angular-app
cd my-angular-app



Step 2: Generate a new component using Angular CLI

Angular CLI provides a convenient way to generate components. Use the ng generate component command (shortened to ng g c) followed by the name of your component (my-component in this example). This command will create the necessary files for your component, including a TypeScript file, an HTML template file, and a CSS stylesheet file.

ng generate component my-component


Step 3: Open the generated component file

Open the generated TypeScript file (my-component.component.ts) in your preferred code editor. This is where you can add custom logic, properties, and methods to your component. The @Component decorator is used to specify the component's selector, template URL, and style URL.

import { Component } from '@angular/core';

  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
export class MyComponentComponent {
  // Component logic and properties go here


Step 4: Open the generated component template file

Open the generated HTML template file (my-component.component.html) in your code editor. Here, you can define the structure and content of your component using HTML markup. In this example, we have a heading (<h1>) and a paragraph (<p>) element.

<h1>How to Create Components in Angular 16 - Websolutionstuff</h1>
<p>This is a custom component created in Angular 16.</p>


Step 5: Open the generated component stylesheet file

Open the generated CSS stylesheet file (my-component.component.css) in your code editor. Here, you can add custom styles specific to your component. In this example, we have added styles for the heading (h1) and paragraph (p) elements.

h1 {
  color: blue;

p {
  font-size: 16px;


Step 6: Use the component in your application

To use the created component in your application, you need to include its selector in another component's template. In this example, we open the app.component.html file and add the selector <app-my-component></app-my-component>. This will render the my-component component within the app component's template.



Step 7: Run the Angular application

To see the created component in action, you need to run the Angular application. Use the ng serve command to start the development server. Open your web browser and navigate to http://localhost:4200 to see your application running.

ng serve

By following these steps, you can create and customize components in Angular 16. This allows you to define reusable UI elements with their own logic and styles, enhancing the modularity and maintainability of your Angular application.
