pnpm

name	pnpm
description	pnpm — fast, disk-efficient package manager with workspace monorepo and content-addressable store.

pnpm

Workspace Monorepo

• pnpm-workspace.yaml: packages: - 'apps/*' - 'packages/*' — define workspace members.
• Local dependencies: "@repo/ui": "workspace:*" — resolved from workspace.
• pnpm add respects workspace protocol; pnpm publish rewrites workspace: semver.

Content-Addressable Store

• Single global store (~/.pnpm-store) — deduplicated by content hash.
• Hard links inside node_modules — saves disk space across projects.
• pnpm store prune — remove unreferenced packages; pnpm store status — check integrity.

Dependency Resolution

• Strict hoisting: only direct deps in node_modules/.pnpm — prevents phantom dependencies.
• pnpm.overrides in package.json — force version resolution.
• pnpm.peerDependencyRules.allowedVersions — allow specific peer ranges.
• .npmrc — shamefully-hoist=true for legacy compat.

Filter & Recursive

• pnpm --filter <name> add dep — scoped to workspace member.
• pnpm -r build — run across all packages; pnpm -r --parallel — concurrent.
• pnpm --filter "{packages/*}..." — glob filters with dependents graph.

Publishing

• pnpm publish --recursive — publish changed packages.
• pnpm pack — create tarball; pnpm publish --dry-run — preview.
• Package patching: pnpm patch <pkg> / pnpm patch-commit <dir>.
