I would refactor this to:

Any particular reason why you have implemented this as an env variable (process.env.CREATE_GITHUB_RELEASE) and not as an input of the action?

Not really, I just didn't learn about this way 😓

Fixed, but I start to wonder where we can document all these action inputs?

It should be added and documented~ in this file: https://github.com/changesets/action/blob/f4afbea27e0f68b63e3e018d053582abee1817b6/action.yml

The additional documentation about it in the README would also be cool but we can do that later.

Added document in the action.yml file

I still kinda think that this should be moved outside of the createRelease function - if I call such a function I expect it to actually do what it is named after. Kinda a single-responsibility approach.

Updated!

I've just learned about this helper function that can probably be used here:

I believe that it takes the default declared in the .yml file into consideration but it would be great if we could confirm that.

I don't think this is safe to do. That function (right from its type-def returns a boolean), but this is optional.

https://github.com/actions/toolkit/blob/daf8bb00606d37ee2431d9b1596b88513dcf9c59/packages/core/src/core.ts#L171-L182

In case people don't provide this (which is pretty much for all current users), it would throw error.

What we need to do is probably:

getOptionalInput("createGithubReleases") ? core.getBooleanInput("createGithubReleases") : true

Regardless, I have updated to use this new syntax

I think that if it's not safe to do then we've made a horrible mistake merging this: https://github.com/changesets/action/pull/131/files#diff-a2a171449d862fe29692ce031981047d7ab755ae7f84c707aef80701b3ea0c80R17 . While merging I didn't notice that it's using this getBooleanInput and I didn't check it back then. If this would throw then we'd already have some angry users in the issues about broken workflow runs 😅

I think that the defaults might be provided by the workflow runner using environment variables:
https://github.com/actions/toolkit/blob/daf8bb00606d37ee2431d9b1596b88513dcf9c59/packages/core/src/core.ts#L129-L130

I'll try to recheck this later in my private playground repo.

Could also be because people are using changesets/action@v1 like in the README.md file 😅
A bit unrelated, do you know why this action doesn't show up in Github action marketplace, i.e. why don't we have this in our repo page?

I've rechecked in my private github actions playground and it seems like a call to core.getBooleanInput("createGithubReleases") is enough :)

Not sure, I'm not sure what's the requirement for this.
