Eleventy Plugin Webc

Overview

The eleventy-plugin-webc is a plugin that adds support for WebC, the single file web component format, to the Eleventy static site generator. This plugin allows users to create first-class components in Eleventy, expanding HTML elements to HTML with defined conventions from web standards. WebC components are compatible with server-side rendering and are Progressive Enhancement friendly. The plugin also provides features such as incremental builds, streaming compatibility, scoped component CSS, and easy bundling of CSS and JS for page-specific bundles. It can handle complex templating needs and works well with web component hydration using is-land.
