metalsmith-html-minifier

A Metalsmith plugin that minifies HTML files using kangax/html-minifier. Current stable version is 4.0.1, compatible with Node.js >=8. It offers built-in defaults that aggressively optimize HTML (e.g. collapsing whitespace, removing comments, removing attribute quotes) which may break conditional comments or whitespace-sensitive layouts. Unlike generic HTML minifiers, it integrates directly into the Metalsmith build pipeline, supporting glob patterns and custom minifier options. Release cadence is low; no major updates since 2019.
