docfonts

Document font substitution, measured.

docfonts publishes @docfonts/fallbacks, a small runtime package for document renderers. It maps common proprietary document fonts to reviewed open-font fallback decisions. It ships no font binaries and no proprietary data.

Built by the team behind SuperDoc. Standalone and neutral.

Structure

• packages/fallbacks - runtime fallback decisions and lookup helpers.
• tools/corpus - local source acquisition and comparison tools.

Use

• Runtime: install @docfonts/fallbacks and call the lookup helpers.
• Acquire: run bun run corpus:acquire to download open-font sources into an ignored local cache.
• Compare: run bun run corpus:compare to rank acquired open fonts against a licensed local reference. Results stay local unless deliberately published through a curated product surface.

Install

npm install @docfonts/fallbacks

Dev

bun install
bun run typecheck
bun run test
bun run lint
bun run build

Release

@docfonts/fallbacks is released by the release-fallbacks workflow on every push to main. semantic-release publishes a new version when the merged commits contain a releasable Conventional Commit. The same workflow can still run manually as a dry run.
