How to Create Web Component

As of 2023, the support for web components, alternatively referred to as custom elements, across browsers is exceptionally robust. Now is an opportune moment to embark on the journey of crafting your personalized elements for the web.

Web components, synonymous with custom elements, represent novel HTML elements that you can personally construct. These elements encapsulate a combination of markup, style, and interactive features.

Example

// mycomponent.js class CurrentDate extends HTMLElement { // The browser calls this method when the element is // added to the DOM. connectedCallback() { // Create a Date object representing the current date. const now = new Date(); // Format the date to a human-friendly string, and set the // formatted date as the text content of this element. this.textContent = now.toLocaleDateString(); } } // Register the CurrentDate component using the tag name <current-date>. customElements.define('current-date', CurrentDate); // index.html <h2>Today's Date: <current-date></current-date></h2>
