Cancel superseded pull request runs.

Each new pull request commit starts the full Node.js matrix while older runs continue. Add a concurrency group keyed by the pull request number or branch ref, with cancel-in-progress: true, to stop obsolete builds.

GitHub Actions pull_request GITHUB_REF synthetic merge commit actions/checkout default ref documentation

💡 Result:

When a workflow is triggered by a pull_request event (for an open, mergeable pull request), GitHub automatically creates a temporary synthetic merge commit that represents the result of merging the pull request's head branch into the base branch [1][2]. Key technical details regarding GITHUB_REF and actions/checkout: 1. GITHUB_REF Value: During a pull_request event, GITHUB_REF is set to the fully-qualified reference of this synthetic merge branch, formatted as refs/pull/<PR_NUMBER>/merge [3][2][4]. 2. Default actions/checkout Behavior: Because the actions/checkout action uses GITHUB_REF by default, it automatically checks out this synthetic merge commit [1][5]. This ensures that your CI tests and workflow steps run against the code as it would exist if the pull request were merged, rather than just the state of the head branch alone [1][5]. 3. Alternative Checkout: If you need to check out the head branch of the pull request instead of the synthetic merge commit, you must explicitly configure the actions/checkout action to use the head SHA [6][7]: - uses: actions/checkout@v4 with: ref: ${{ github.event.pull_request.head.sha }} It is important to note that GITHUB_SHA for a pull_request event similarly points to this synthetic merge commit [1][2]. If your workflow requires the SHA of the actual commit that triggered the pull request, you should access github.event.pull_request.head.sha instead [1][8].

Document the intended pull request revision or check the head commit explicitly. If this workflow must validate the submitted head commit, set ref to ${{ github.event.pull_request.head.sha }}. Otherwise, document that the default synthetic merge commit is intentional.

Restrict the token before running package code.

actions/checkout persists GITHUB_TOKEN in .git/config by default. npm install can run dependency lifecycle scripts that read this token. Set permissions: contents: read and persist-credentials: false.

[Blocker] Invoke the declared project build.

package.json defines build as bun run scripts/build.ts. This workflow runs npm install and npx webpack instead, so it does not validate the project build and may fetch an undeclared Webpack CLI. Set up Bun, install from the lockfile, and run bun run build.
