Documented steps
Run pnpm patch <pkg>@<version> — pnpm extracts the package to a temporary directory for free editing (choose your own location with --edit-dir <dir>).
Edit the extracted files to fix the bug.
Run pnpm patch-commit <path-to-edit-dir> — pnpm generates a patch file and registers it in the patchedDependencies field of your manifest, e.g. patchedDependencies: { 'express@4.18.1': 'patches/express@4.18.1.patch' } in pnpm-workspace.yaml.
Future installs apply the patch automatically. Re-patch on top of an existing patch by default; use --ignore-existing to start from the pristine package.
Patches can target exact versions, version ranges, or bare package names; precedence when several match: exact version > version range > name-only.

Known gotchas
Do NOT use patches to edit a dependency's package.json dependencies — use overrides or a package hook instead; the docs call this out explicitly.
By default installation fails if a registered patch cannot be applied (allowUnusedPatches defaults to false). In v11 patch failures always throw — the old ignorePatchFailures escape hatch was removed, and allowNonAppliedPatches was renamed to allowUnusedPatches (see https://pnpm.io/migration).
In v11, one failing patch doesn't stop the others from attempting — all errors are reported together at the end.
