A lightweight, stand-alone polyfill for the W3C Custom Elements (Web Components) specification, supporting both V0 and V1 APIs in browsers lacking native support. It is now deprecated in favor of @ungap/custom-elements.

Use cases

  • support custom elements in older browsers without native web components
  • polyfill document.registerElement for legacy web components code
  • use custom elements v1 API in browsers like old Edge or IE11
  • provide a ponyfill for customElements registry
  • extend built-in HTML elements in unsupported browsers

When to choose

  • maintaining a legacy codebase already built on document-register-element
  • needing custom elements with builtin extends in very old browsers

When to avoid

  • starting a new project - use @ungap/custom-elements or native custom elements instead
  • targeting only modern browsers with native customElements support
