Reduce dependencies management overhead.

What changes did you make? (Give an overview)

The post configuration on the repo needs an admin: https://github.com/renovatebot/renovate/blob/main/docs/usage/getting-started/installing-onboarding.md

Or do like eslint-plugin-n and move to Renovate: eslint-community/eslint-plugin-n#44 (see dependency dashboard at eslint-community/eslint-plugin-n#150)

This would be preferable I think, and we could eventually do a superset / alternative renovate config for eslint-community rather than just using the ESLint one directly, and that could be shared between eg. plugin-n and plugin-promise

[jerome-benoit]

The intent was to reduce the deps maintenance overhead with a minimum work and the current tooling: instead of having X PRs to review/merge, you now have 2 PRs maximum with the minimum sensible update semantic.

Changing the deps maintenance tooling for better one was not the scope.

[voxpelli]

Sure, but I would rather align across this and eg. eslint-plugin-n rather than have each do their own thing. Any downside to that?

[jerome-benoit]

The amount of work is not the same, at all.

And the two are not mutually exclusive:

• 5 min work and a few lines of code to improve the current situation
• An issue to switch to renovate later with the creation of whatever shared configuration for eslint plugins: hours of work

Adding the same renovate config as eslint-plugin-n requires simply removing the dependabot config and adding a .github/renovate.json file with:

{
    "$schema": "https://docs.renovatebot.com/renovate-schema.json",
    "extends": ["github>eslint/eslint//.github/renovate.json5"]
}

It would take me mere minutes to do, but want opinions from eg. @brettz9 and @scagood before doing so

Im in favour of copying the other community repos too 👍

Haven't used Renovate personally, but no strong opinions about it either way.

(In my personal projects I like to just use npm-check-updates to periodically update dependencies locally, without any remote noise at all. :-) )

I am in favour of this, thank you 💪

Merged, thanks @jerome-benoit 🙏

The original issue of the grouping is something we can revisit when we see how this works out 👍
