esbuild-plugin-html-modules

An esbuild plugin that enables loading HTML files as ES modules, following the WICG HTML Modules proposal. Version 0.9.1 allows importing HTML files with `import` statements, where the HTML template becomes the default export and `<script type="module">` code runs as the module script. Supports configuration for global CSS extraction, local style transformation via PostCSS, and custom file filters. Key differentiator: enables web component authors to co-locate templates, scripts, and styles in single HTML files with standard ES module semantics. Released weekly, actively maintained.
