Getting Started with Web Components
Web Components are a set of web platform APIs that allow you to create custom, reusable, encapsulated HTML tags for use in web pages and web apps. They're built on web standards and work across modern browsers.
Here's a simple example of a custom element:
class MyElement extends HTMLElement {
constructor() {
super();
this.attachShadow({ mode: 'open' });
}
connectedCallback() {
this.shadowRoot.innerHTML = `
<style>
p { color: blue; }
</style>
<p>Hello from Web Component!</p>
`;
}
}
customElements.define('my-element', MyElement);
The beauty of Web Components is that they provide true encapsulation and can be used in any framework or with vanilla JavaScript.
