Move signal-exit from devDependencies to dependencies. Fixes #3185

[hudochenkov]

Which issue, if any, is this issue related to?

#3185

Is there anything in the PR that needs further explanation?

I don't know how to test it. Or recreate a problem. But this package is required in our code. Even, though, we don't use sync method in writeFileAtomic.js, which is the only place uses this package.

@hudochenkov need patch release 😞

• Fixed: missing signal-exit dependency (#3186).

@hudochenkov need patch release 😞

I'll do one now.

[jeddy3]

Released as 9.1.1.

I might be remembering incorrectly, but didn't we add an eslint plugin or something similar to protected us from these missing dependencies issues?

[hudochenkov]

Thanks, @jeddy3!

[hudochenkov]

@jeddy3 we do have such rules, but they won't protect from this situation. We have package in package.json, and it exists. I don't thinks it's possible to know if required package should be in devDepenendencies or in dependencies.

no-missing-require
no-extraneous-require

That discussion was in #2978, it primarily revolved around the eslint-plugin-node no-unpublished-require rule, this rule doesn't cover what occurred in this case.

I had a quick look at the other rules not included in the eslint-plugin-node/recommend ruleset that we use and none of those would have detected that either.

Something to keep a lookout for, or possibly create a new ESLint rule maybe

I tried using this plugin https://www.npmjs.com/package/eslint-plugin-implicit-dependencies and reverting the change in this PR, the result:

And signal-exit is not listed as one of those missing, its also not listed once I remove it completely from package.json
