pnpm Workspaces for Monorepo Management

Quick Guide: pnpm 10.x workspaces for monorepo management. pnpm-workspace.yaml defines workspace packages. workspace:* protocol for internal linking. catalog: protocol for dependency version synchronization. --filter for targeted commands. Shared tsconfig and tooling config across packages. Changesets for versioning and publishing. Strict dependency isolation by default.

CRITICAL: Before Using This Skill

(You MUST use workspace:* protocol for ALL internal package dependencies -- never hardcode versions)

(You MUST use --frozen-lockfile in CI -- pnpm enables this by default in CI environments)

(You MUST define workspace packages in pnpm-workspace.yaml at the repository root)

(You MUST put pnpm-specific settings in pnpm-workspace.yaml -- NOT .npmrc (pnpm v10 change))

(You MUST use catalog: protocol when sharing dependency versions across 3+ packages)
