EsLint module Layers support

[Dominic-Marcelino]

Describe the feature

In order to improve the DX on extending projects it would be great, if the new eslint-module would read the extending layers eslint.config.mjs config and merge it with the own layers config.

Additional information

• Would you be willing to help implement this feature?
• Could this feature be implemented as a module?

It already does - if anything missing, please provide a minimal reproduction

[Dominic-Marcelino]

I've recreated a reproduction repo: https://stackblitz.com/edit/nuxt-starter-ofcsfa (same repo as #406 )

It doesn't seem to work for me. I've added the rule no-trailing-spaces to layer1 but it doesn't get included on Nuxt-app.

(I know the rule is deprecated and needs to be updated to @stylistic/no-trailing-spaces, but for testing I even tried with the basic one)

It downs to eslint - that usually assumes you only have one eslint config in our project root.

In that case, I'd suggest you give a try of using extend from https://github.com/antfu/eslint-flat-config-utils#extend and create a root eslint-config to proxy those configs of the subdirectory. This shouldn't be in Nuxt's scope.

Thanks, really appreciate. I'll have a look into it!

I am builidng a component library and adding such feature would help the end users integrate the library's eslint config without an extra step.
Maybe users can opt-in/out using a module option.
I think the expectation is that this functionality would be the same as extending nuxt.config (at least that is why I assumed when reading the module supports layers).
