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
