rollup-plugin-font-subsetter

A Rollup plugin that subsets webfonts at build time based on the characters used in static source files (HTML, CSS, JavaScript/TypeScript) in the bundle. Current stable version: 0.2.0. Release cadence: low, experimental. Key differentiators: automatically extracts character set from bundled assets, uses subset-font under the hood, ships TypeScript types, supports only .woff2 format. Compared to alternatives like 'font-spider' or manual subsetting, it integrates directly into the Rollup build pipeline and requires no runtime overhead. Limitations: does not handle dynamic content or obfuscated code; character set extraction may be incomplete.
