node20 support

[MikeMcC399]

Please provide a new release of pnpm/action-setup which runs under node20 as Node.js 16 reached end-of-life on Sep 11, 2023.

action-setup/action.yml

Lines 22 to 25 in 0b715c7

	runs:
	using: node16
	main: dist/index.js
	post: dist/index.js

See the announcement GitHub Actions: Transitioning from Node 16 to Node 20.

Edit: Removed the request for a certain release number.

Wouldn't that only affect the pnpm/action-setup runtime? Why should it be a major version bump?

Hi @zkochan

Wouldn't that only affect the pnpm/action-setup runtime? Why should it be a major version bump?

Sorry if the request was unclear. Yes, this is only about creating a new release of pnpm/action-setup from this repo. I don't know if this would be a breaking change for the action, but in other situations moving from Node.js 16 to 18 or later can break things, so it's just safer to use a new major version number.

Users of pnpm/action-setup@v2 will start to get a deprecation warning from GitHub Actions on October 23, 2023 when they run it, so if you release pnpm/action-setup@v3 to work with node20 that would make it a clear move. Also if the update does cause a breaking change, anybody who has specified pnpm/action-setup@v2 will not get a bad surprise of their workflow breaking. They have about 6 months to manually specify @v3 instead, if that is what they want, and if they don't update then GitHub will anyway force using node20 after this time.

The actions from GitHub which migrated from node16 to node20 like actions/checkout made a new major release (in this example from actions/checkout@v3 to actions/checkout@v4). Same for cycjimmy/semantic-release-action which also did a new major release from @v3 to @v4.

I am not sure why do they mark this as breaking if only the action's own runtime changes. The projects using the action will not run on a different node.js version.

@zkochan

• I see that you started to work on this issue in fix: update node.js to v20 #102 and all your checks are failing.

According to the announcement GitHub Actions: Transitioning from Node 16 to Node 20 deprecation notices are supposed to start being displayed today.

[zkochan]

It is not so easy to do because this action uses a deprecated tool that doesn't work on node.js 20. So, we might have to do a big rewrite.

[MikeMcC399]

@zkochan

Thanks for your update and I'm sorry that this could be a time-consuming task for you. I guess it will be about 6 months until GitHub finally blocks node16. (They say "Spring 2024".)

[MikeMcC399]

GitHub is now producing the expected deprecation warning, for instance:

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: pnpm/action-setup@v2, actions/cache@v3. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

This also impacts actions/cache@v3 listed in the README.

[MikeMcC399]

The warning has been disabled temporarily, as it became clear that GitHub's own actions also were not ready.

The warning is back:

Is the work to update node version on the roadmap for the following months?

[MikeMcC399]

@oanaOM

Your error message shows that you are using pnpm/action-setup@v2.2.1 from Feb 2022.

If you specify pnpm/action-setup@v2 (or pnpm/action-setup@v2.4.0) you should not see this warning which refers to node12 not node16

[oanaOM]

Ah, you are very right. Once I changed the version of the action I don't see the warning anymore. thanks you for your help!

[pavelzw]

the warning also gets produced with the latest version 2.4.0

[MikeMcC399]

I'm not seeing any warnings on GitHub-hosted runners at this time, however the GitHub team said they wanted to re-enable the warnings again soon. Edit: warnings have been re-enabled.

If this issue is not able to be resolved soon, then I would convert from using pnpm/action-setup and instead install pnpm with npm i.e. run: npm install pnpm@8 -g since the call that I'm looking at doesn't use any of the parameters of the action apart from the version number.

Edit: I now converted to not use the action pnpm/action-setup.
