pnpm build

Or from the repo root:

Test files should live within a tests/ file in the src/ folder. Unit tests should end in .test.ts and integration tests should
end in .int.test.ts:

pnpm lint && pnpm format

If you add a new file to be exported, either import & re-export from src/index.ts, or add it to the exports field in the package.json file and run pnpm build` to generate the new entrypoint.
