fix(ci): keep pnpm warnings out of the preview release JSON - #406
Merged
Conversation
The Preview Release job builds the affected packages before running
scripts/publish-preview-release.js. That build rewrites the
`typesVersions` field of the built package.json files, so every pnpm
invocation afterwards prints
[WARN] Your node_modules are out of sync with your lockfile
on stdout — in front of the `nx show projects --json` output the script
parses, which then dies with "Unexpected token 'W'" and fails the job on
every pull request that touches a package.
Run the command through `pnpm --silent exec`, which keeps pnpm's own
reporter off stdout and leaves nx's JSON as the only output.

Pass CHANGED_FILES as an argument, not shell text.
Because this workflow runs for pull requests, a contributor can control changed filenames. execSync passes CHANGED_FILES through a shell, which allows command injection and breaks filenames containing spaces.
Use execFileSync with an argument array. Pass --files=${process.env.CHANGED_FILES} as one argument.

The Preview Release job has been failing on every pull request that touches a package — #402's branch, the renovate branches, and all three of #403/#404/#405:
Cause
The job's Build step runs
build:affected:packages:prod, and packem's node10-compatibility plugin rewrites thetypesVersionsfield of the builtpackage.jsonfiles ("Your package.json 'typesVersions' field has been updated"). From that point the workspace manifests no longer match the install, so every pnpm invocation prints the out-of-sync warning — on stdout, not stderr.The next step is
node ./scripts/publish-preview-release.js, which doesJSON.parseon the stdout ofpnpm exec nx show projects … --json. The warning lands in front of the JSON and the parse dies, failing the job.Fix
pnpm --silent exec— the silent reporter keeps pnpm's own output off stdout and leaves nx's JSON as the only thing printed.Reproduced locally by putting a workspace manifest out of sync with the lockfile:
With the same drift in place,
CHANGED_FILES=… node ./scripts/publish-preview-release.jsnow gets through the parse and on to the publish step (which only fails locally becausepkg-pr-newrequires GitHub Actions).This leaves the build's manifest rewriting alone — it is packem doing its job — and just stops the script from choking on the warning it causes.
