Sunset is a web app for experimenting with font subsetting.

• Bun
• hb_subset (from HarfBuzz)
• woff2
• 7zz

Make sure every CLI listed above is available on the PATH of the server process.

bun install

This will install dependencies for every workspace in the repo.

• Run both the server and client: bun run dev
• Server/client only: bun run -F <server | client> dev

The server listens on http://localhost:4321 by default. You can adjust the maximum accepted request size by setting the MAX_SIZE environment variable (bytes).

Server-side font subsetting tests live under pkgs/server/test. Run them with:

bun test pkgs/server/test

You can build a container image of the server using the provided Dockerfile:

cd pkgs/server
docker build -t sunset-server .
