Metalsmith HTML Minifier

A Metalsmith plugin that minifies HTML files using kangax/html-minifier. Version 2.2.0 is the current stable release, with a low update cadence (last updated in 2018). Key differentiators: it integrates seamlessly with Metalsmith build pipelines, supports glob patterns for file selection, and provides sensible defaults while allowing full configuration of html-minifier options. It enables several optimizations by default (e.g., collapsing whitespace, removing comments), which users should disable explicitly if undesired. The plugin is lightweight with no runtime dependencies beyond metalsmith and html-minifier.
