pnpm monorepo workflows (Cloudflare Workers SaaS kit)

Use this skill whenever the user asks to set up the repo, run dev servers, rebuild shared packages, or troubleshoot script execution.

Key packages

• •apps/user-application: TanStack Start (SSR) app running on Cloudflare Workers
• •apps/data-service: Backend API Worker (Hono)
• •packages/data-ops: Shared library for Drizzle ORM + Better Auth

Setup

• •Initial setup (install + build shared lib): pnpm run setup

Dev servers

• •User app dev: pnpm run dev:user-application (typically on port 3000)
• •Data service dev: pnpm run dev:data-service

Shared package builds

• •Rebuild shared library after changes: pnpm run build:data-ops

Script hygiene

• •Use pnpm -w ... only if a script is defined at workspace root.
• •Prefer package-scoped scripts:
  • •pnpm --filter data-ops <script>
  • •pnpm --filter user-application <script>
  • •pnpm --filter data-service <script>

Linting & typechecking

• •Lint UI package: pnpm --filter @workspace/ui lint
• •Typecheck a single package/app (recommended when debugging TS issues):
  • •pnpm -C apps/user-application tsc --noEmit
  • •pnpm -C apps/data-service tsc --noEmit
  • •pnpm -C packages/data-ops tsc --noEmit
  • •pnpm -C packages/ui tsc --noEmit

Troubleshooting quick checks

• •Ensure pnpm-lock.yaml is consistent (avoid mixing npm/yarn).
• •If types/bindings changed, regenerate worker types (see the worker typegen skill).
• •If packages/data-ops changed and consumers are broken, run pnpm run build:data-ops and restart dev servers.
