🟣 This is a pre-existing issue: packages/middleware/express/package.json uses npm run build in its prepack script, and packages/middleware/fastify/package.json uses npm run in both prepack and check scripts, inconsistent with the project-wide pnpm workspace setup. While unlikely to cause failures in most environments, CI/CD pipelines enforcing pnpm-only or environments without npm installed could fail at publish time; these should be changed to pnpm run.

Extended reasoning...

The project uses pnpm as its package manager throughout. PR #1534 included a changeset specifically to remove npm references and clean up package manager usage, yet the express and fastify packages were missed.

Affected locations:

  • packages/middleware/express/package.json: prepack uses npm run build
  • packages/middleware/fastify/package.json: prepack uses npm run build, and check uses npm run typecheck && npm run lint

Code path that triggers it: The prepack lifecycle hook runs automatically before pnpm publish. When a maintainer publishes these alpha packages (exactly what this PR prepares), Node invokes the prepack script which shells out to npm run build. In a pnpm-only environment, npm may not be available.

Why existing code does not prevent it: Simple human oversight - the express and fastify packages were not updated when PR #1534 cleaned up npm references elsewhere. Sibling packages (client, server, hono, node) all correctly use pnpm run.

Impact: In practice, npm run can invoke local scripts just as pnpm run, so failures are rare in developer environments. However, strict CI/CD pipelines with only pnpm installed, or environments with package manager enforcement, would fail at publish time during the prepack step.

Step-by-step proof:

  1. packages/middleware/hono/package.json: prepack = pnpm run build, check = pnpm run typecheck && pnpm run lint (correct)
  2. packages/middleware/express/package.json: prepack = npm run build (inconsistent)
  3. packages/middleware/fastify/package.json: prepack = npm run build, check = npm run typecheck && npm run lint (inconsistent)
  4. This PR bumps these packages to alpha.2 for publishing - triggering prepack is exactly the scenario where this matters

Fix: Replace npm run with pnpm run in the three affected script entries in express and fastify package.json files.
