Prefer `node-version-file: package.json` over $PATH by default

[fregante]

Description:

- uses: actions/setup-node@v5

Currently this uses what's available in $PATH, but I reckon it should prefer what the user already specified as a compatible node version in the package.json.

Justification:

It feels strange that a project clearly and "natively" specifies what version it's expected to run on, but the environment ignores it, requiring further config.

I love that node-version-file: package.json is possible now, but I wish I didn't have to clutter all of my jobs with

- uses: actions/setup-node@v4
  with: 
    node-version-file: package.json

. . . 


- uses: actions/setup-node@v4
  with: 
    node-version-file: package.json

. . .

- uses: actions/setup-node@v4
  with: 
    node-version-file: package.json

The drawback is that in the rare situation where the user wants to use what's in PATH, as opposed to what's in package.json, now they'd need something like node-version: PATH. But again this feels like it should be the minority.

Are you willing to submit a PR?

Potentially

Hello @fregante, We've merged the fix for the issue as part of another issue. Could you please try to use actions/setup-node@main to confirm that it works as expected?

[fregante]

Thank you! Unfortunately that didn't seem to work.

Hello @fregante, Thank you for testing.
Could you please replace the setup-action repository actions/setup-node@v4 in your workflow with actions/setup-node@main because we have merged the code as part of this PR and yet to release.
Please replace the branch with main and update the results. Hope that should fulfil your requirement.

without node-version-file, on @main ❌

we have merged the code as part of this PR

That PR is unrelated to this feature request.

The tests on main specifically verify the opposite of this feature request, right?

Great issue and great research. I was just wondering the same thing, would be great if the version would just work™

Additionally, this would provide a nice way to configure both the node and npm version. Currently, actions/setup-node will install a npm version that does generally not match pkg.engines.npm. If one wants to ensure that the npm version is the same as the one used locally, one has to run npm install --global npm@... after actions/setup-node which is cumbersome.
