Web Components serve as the fundamental building blocks for creating modular and reusable interfaces on the web. This chapter introduces the concept of Web Components, exploring the use of Custom Elements and Shadow DOM to empower developers in building versatile and encapsulated UI elements.

Introduction to Web Components

Web Components are a set of web platform APIs that allow developers to create reusable and encapsulated components. They promote modularization, reusability, and maintainability in web development. A Web Component typically consists of three main parts:

  1. Custom Elements: Define new HTML elements with custom behavior.
  2. Shadow DOM: Encapsulate the internal implementation details of a component, preventing styles or scripts from leaking out and vice versa.
  3. HTML Templates: Declare fragments of markup that can be cloned and inserted into the DOM.

Let’s explore a simple example of creating a Web Component using Custom Elements:


class CustomCard extends HTMLElement {
  constructor() {
    super();


    const shadow = this.attachShadow({ mode: 'open' });


    const template = document.createElement('template');
    template.innerHTML = `
      <style>
        
        :host {
          display: block;
          border: 1px solid #ccc;
          padding: 16px;
          border-radius: 8px;
        }
      </style>
      <div>
        <!-- Content of the component -->
        <slot></slot>
      </div>
    `;


    shadow.appendChild(template.content.cloneNode(true));
  }
}


customElements.define('custom-card', CustomCard);

In this example, we’ve defined a CustomCard class that extends HTMLElement. It creates a Shadow DOM, applies styling specific to the component, and utilizes a template to structure the component’s content. The customElements.define method is then used to register the custom element with the browser.

Custom Elements and Shadow DOM: Creating Modular Interfaces

Custom Elements: Custom Elements enable developers to define their own HTML elements with encapsulated functionality. These elements can be reused across different parts of an application or even in different projects. For example, once the ‘custom-card’ element is defined, it can be used in HTML like any other standard HTML element:

<custom-card>
  <h2>Card Title</h2>
  <p>Content of the card...</p>
</custom-card>

Shadow DOM: Shadow DOM ensures encapsulation by creating a boundary between the component and the rest of the document. This prevents styles and scripts from affecting or being affected by the outer document. The <slot> element in the example allows the insertion of content into the component from the outside.

Web Components, with Custom Elements and Shadow DOM, offer a powerful mechanism for creating reusable and encapsulated components, promoting clean and maintainable code in web development.
