研究方向

Read the version input handling and Node.js version resolution entry points, then compare how actions/setup-python handles allow-prereleases, as linked in the issue. Check the existing tests for version selection and add coverage for the default false behavior and enabling prerelease resolution. Done when node-version: 27 selects the available alpha only with the option enabled.

描述

feature request

Description:

Add an option allow-prereleases, like in actions/setup-python, so that Node.js 27 Alpha can be selected simply using:

    - uses: actions/setup-node@v7
      with:
        node-version: 27
        allow-prereleases: true

allow-prereleases should default to false.

Justification:

Evolving the Node.js Release Schedule explains how Node.js has introduced a 6 month Alpha phase for new Node.js release lines. This is important for pre-testing and it replaces the previous system of odd- and even-numbered releases, where only the even-numbered release lines were promoted to LTS (Long Term Support).

For ongoing CI testing during the 6 month Alpha phase, GitHub Actions workflows need to be able to specify a generic version of Node.js 27 without having to update a workflow every time there is a new Alpha release (probably every 2 weeks):

None of the following are currently recognized:

  • 27
  • 27.0.0
  • 27.0.0-alpha

only the explicit 27.0.0-alpha.0.0.0 is working:

    - uses: actions/setup-node@v7
        with:
        node-version: 27.0.0-alpha.0.0.0

Are you willing to submit a PR?

No, I won't be able to do this.

Workaround

Specify the exact Node.js Alpha version or latest:

    - uses: actions/setup-node@v7
        with:
        node-version: 27.0.0-alpha.0.0.0

Edit: according to the discussion in https://github.com/actions/setup-node/issues/1660 latest will be changed to install the latest non-alpha version, so the following will not be a future workaround:

    - uses: actions/setup-node@v7
        with:
        node-version: latest
