What are web components?

Web components are a set of web technologies that allow you to create custom reusable HTML elements. These elements are not dependent on using a specific framework. You can use them without having to load a framework like React or Angular.

To build a web component, you can use these three technologies:

  • Custom Elements: A JavaScript API that allows you to create custom elements which you can use like HTML tags.
  • Shadow DOM: The Shadow DOM API provides a way to attach a hidden and separate Document Object Model to a web component. This keeps your component’s HTML, CSS and JavaScript separate from the rest of the web page.
  • HTML Templates: Use HTML tags <template> and <slot> to hold HTML that doesn’t display when the page loads. You load it with JavaScript at a later time.

Can I use web components in a JavaScript framework?

Yes. You can use your component in whatever JavaScript framework you want or none at all. If you need to switch to a new framework, you don’t have to rewrite your web component. Learn how to get started with building a web components.
