Closes #8. Closes #10.

What this adds

A boolean require-lockfile, default false:

- uses: pnpm/setup@v2
  with:
    require-lockfile: true

When set, the install has to be fully described by pnpm-lock.yaml. install stays the boolean it has always been — the two are orthogonal (whether to install at all, and whether the install must be described by a lockfile), and folding the second into the first would have meant turning a boolean input into an enum, with an empty-value error to go with it.

It fails before running pnpm

A missing lockfile is the whole reason the input exists, so the action answers that itself:

`require-lockfile` is set but no pnpm-lock.yaml was found in . or above it.
Commit the lockfile, or unset `require-lockfile` to let pnpm resolve and write one.

Running the install first only reaches the same conclusion later and through a worse message. The search goes upward from working-directory, the way pnpm locates the workspace root — a project that is a workspace member keeps its lockfile above itself, and a check that looked only in the working directory would fail those setups wrongly.

When a lockfile is found, the install runs with --frozen-lockfile.

Why this is narrower than the original proposal

This PR was first written against 12.0.0-rc.3, where pnpm 12 applied no CI frozen-lockfile default at all. That was fixed before 12.0.0 shipped. Retested on the released versions, with an out-of-date lockfile and CI=true:

pnpm exit lockfile
11.22.0 1 unchanged
12.0.0 1 unchanged

The majors agree again, and GitHub Actions always sets CI, so an out-of-date lockfile already fails a plain install. require-lockfile adds nothing there.

What the CI default still does not do is require a lockfile to exist:

CI=true pnpm install, no lockfile:      exit=0, lockfile written   (11 and 12)
pnpm install --frozen-lockfile, none:   exit=1                     (11 and 12)

A repository that never committed pnpm-lock.yaml — or .gitignored it, or used a sparse checkout — resolves fresh from the registry and goes green on unpinned dependencies. That single case is the whole justification for this input.

It narrows further: with cache: true a missing lockfile already fails, because hashFiles matches nothing and the cache restore throws. require-lockfile fails with a message that names the real problem, and covers cache: false jobs too.

What was dropped

The ci mode from the original proposal. pnpm ci is pnpm clean plus --frozen-lockfile, and the clean half only matters when node_modules survives between runs — this action caches the pnpm store, not node_modules, so on ephemeral runners it is a no-op with a cost. Worth revisiting if self-hosted users ask for it.

Also in here

Two fixes from the original that stand on their own, independent of the feature:

  • Failure messages and the log group name the command actually run, flags included.
  • A process killed by a signal reports status: null with no error, so the previous truthiness check on status treated it as success. Now checked explicitly.

About the default

Issue #10 also asks for frozen installs by default. This PR does not change the default — that would break workflows that rely on the lockfile being updated, and belongs in a major.

Tests

One job covering the three states in sequence:

  • an up-to-date lockfile installs, and the lockfile is byte-identical afterwards;
  • with the lockfile removed, the step fails;
  • from that same state without the input, the install succeeds and writes a lockfile — the contrast that shows what the input actually buys, since pnpm's CI default does not require one.

📝 Walkthrough

Walkthrough

The action now supports install, require-lockfile, and disabled installation modes. It validates input values, resolves project paths, runs the matching pnpm command, and verifies frozen-lockfile behavior in integration tests.

Changes

Install mode support

Layer / File(s) Summary
Install mode contract
src/inputs/index.ts, action.yml, README.md
The install input now supports true/install, require-lockfile, and false. Invalid and empty values fail. Documentation describes frozen-lockfile behavior and project-path handling.
Command selection and execution
src/pnpm-install/index.ts
Disabled installs return early. require-lockfile adds --frozen-lockfile. Runtime installs add --no-runtime. Command failures and signal termination now report explicit failures.
Integration coverage
.github/workflows/test.yaml
Workflow jobs verify matching and missing lockfile behavior, unchanged lockfiles, and rejection of invalid or empty values.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to c8ab3

The PR adds an opt-in frozen-lockfile install mode while preserving existing install behavior. Merge is reasonable with owner awareness of two bounded issues: the updated workflow retains checkout credentials without a demonstrated need, and cache-path documentation may mislead users when working-directory is changed.

Pull request overview

Adds support for multiple install modes in the action so workflows can choose between a normal install, a frozen-lockfile install, a CI-style clean install, or skipping installs entirely.

Changes:

  • Extend the install input to accept true/install, frozen-lockfile, ci, or false.
  • Update install execution to run the selected pnpm command (pnpm install, pnpm install --frozen-lockfile, or pnpm ci) and improve related messaging.
  • Document the new modes and add workflow coverage for the new install behaviors and validation.

Review feedback on pnpm#23:

- `command` was built before `--no-runtime` was appended, so a failing
  install reported `pnpm ci` while the log showed `pnpm ci --no-runtime`.
  Build it from the final args so every message matches.
- `if (status)` treated a signal-terminated install as success, since
  spawnSync reports `status: null` with no `error` in that case. Fail on
  `signal`, and use `status !== 0`.

Review feedback on pnpm#23. The value now describes what it guarantees — the
install must be fully described by pnpm-lock.yaml — rather than naming the
pnpm flag it happens to pass. The flag itself is unchanged.

Docs now spell out that this is not the same as pnpm's own CI default: pnpm 11
only blocks updates to an existing lockfile, and pnpm 12 does not apply the CI
default at all as of 12.0.0-rc.3.

Cover the renamed install mode explicitly.

The test rejects install: frozen, but the previous public spelling was frozen-lockfile. If the rename intentionally removes the old spelling, add install: frozen-lockfile as another invalid case. The current test does not verify that contract change.

Learning: When using `actions/exec` (`getExecOutput` / `exec`), it is valid for the `commandLine` option to include both the command and its arguments in a single string (e.g., `getExecOutput('pnpm store path --silent')`). The library tokenizes `commandLine` internally (via `argStringToArray()`), so this behaves like passing an equivalent command + args array (e.g., `getExecOutput('pnpm', ['store','path','--silent'])`). In code reviews, do not flag this as incorrect—this matches documented behavior and a production-tested pattern.

Confidence Score: 4/5

The PR is not yet safe to merge because workflows using the advertised install: require-lockfile mode fail during boolean input parsing.

The implementation exposes lockfile enforcement as a separate boolean while install remains boolean-only, so the mode described by the PR cannot reach the frozen install path.

Confirm the install input spelling.

The implementation, documentation, and tests consistently support require-lockfile, which runs pnpm install --frozen-lockfile; frozen-lockfile is rejected. If the required contract is frozen-lockfile, rename the input and update the documentation and tests. Otherwise, keep require-lockfile as the documented value.

Thanks for this — the investigation in the original description was what made it reviewable, and two of the fixes in it are worth having regardless of the feature. I've rebased onto main and trimmed the scope; here's what changed and why.

Retested against released 12.0.0

The PR was written against 12.0.0-rc.3, where pnpm 12 applied no CI frozen-lockfile default. That was fixed before 12.0.0 shipped. With an out-of-date lockfile and CI=true:

pnpm exit lockfile
11.22.0 1 unchanged
12.0.0 1 unchanged

So the divergence between the majors is gone, and since GitHub Actions always sets CI=true, an out-of-date lockfile already fails a plain install. That mattered beyond the description, because the claim was in action.yml — user-facing docs asserting something no longer true. It's rewritten in action.yml, the README and the commit message.

The justification that survives is the one case the CI default still doesn't cover:

CI=true pnpm install, no lockfile:     exit=0, lockfile written   (11 and 12)
pnpm install --frozen-lockfile, none:  exit=1                     (11 and 12)

A repo that never committed a lockfile installs unpinned and goes green. That's now the stated reason for the mode.

Dropped the ci mode

pnpm ci is pnpm clean plus --frozen-lockfile, and the clean half only matters when node_modules survives between runs. This action caches the pnpm store, not node_modules, so on ephemeral runners it's a no-op with a cost. Happy to revisit if self-hosted users ask for it.

Changed what the regression test asserts

The original asserted require-lockfile fails on an out-of-date lockfile — but per the table above that now fails a plain install too, so it no longer distinguishes the mode. The job now removes the lockfile entirely and asserts the step fails and writes nothing. Your success case (lockfile byte-identical after a passing run) is kept as-is, and the invalid-value job is unchanged.

Rebase details worth knowing

main moved a lot while this was open, and two interactions needed resolving by hand rather than mechanically:

I also left the install === false check in src/index.ts rather than taking your move of it into runPnpmInstall. main needs that conditional in runMain to gate the lockfile-verification cache save added in #30, so moving it would have broken that bound. runPnpmInstall still early-returns on false, so the skip is safe from either direction.

Kept

Both of your incidental fixes, which are improvements independent of the feature: the signal check (spawnSync reports status: null with no error when killed, so the old truthiness test counted that as success), and rejecting empty values, since an action.yml default only applies when the input is omitted entirely.

50-61: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

State the configured cache-path base consistently.

These descriptions say cache-dependency-path resolves relative to working-directory. resolveCacheDependencyPath() keeps a configured value relative to GITHUB_WORKSPACE; only the default follows working-directory. A user who sets working-directory: docs and cache-dependency-path: pnpm-lock.yaml will select the repository-root lockfile.

  • action.yml#L50-L61: State that configured cache paths are relative to GITHUB_WORKSPACE, while the default is inside working-directory.
  • README.md#L24-L25: Use the same configured-path and default-path distinction.

Comment thread src/inputs/index.ts Outdated
A separate boolean rather than a value on `install`: the two are
orthogonal — whether to install at all, and whether the install has to be
described by a lockfile — and folding them together meant turning a
boolean input into an enum, with an empty-value error to go with it.

When set, the action looks for `pnpm-lock.yaml` in `working-directory`
and above it, the way pnpm searches for the workspace root, and fails
there and then if none exists. Running pnpm first only reaches the same
conclusion later and through a worse message.

The mode is narrower than the proposal it came from. Retested on the
released 12.0.0 rather than the 12.0.0-rc.3 that PR was written against:
an out-of-date lockfile now fails a plain `CI=true pnpm install` on 11
and 12 alike, so the divergence between the majors is gone. What the CI
default still does not do is require a lockfile to exist — with none at
all it resolves from the registry, writes one and exits 0 on both. That
single case is what this closes.

The `ci` mode from the proposal is dropped: `pnpm ci` adds a `pnpm clean`
that only matters when `node_modules` survives between runs, and this
action caches the store rather than `node_modules`.

Failures now name the command actually run, and a process killed by a
signal reports `status: null` with no `error` — a truthiness check on
`status` alone let that pass as success.
