extending unjsPreset

[amery]

Hi, I'm trying to build my own eslint-config package on top of eslint-config-unjs initially by adding vue/recommended and stylistic/recommended, but I haven't figured out 4 things, and I would really appreciate any suggestions.

1. how to procedurally extend RuleOptions with definitions from the plugins I'm loading
2. how to handle duplicates in plugins declarations to be able to work withNuxt() and without
3. ignores: [ '**/dist' ] doesn't do anything unless it's passed via the MainConfig
4. are there types for eslint-plugin-vue?

to make things weirder '@stylistic/semi': ['error', 'always'], only works on userConfigs and not on MainConfig when stylistic's recommended rules are also loaded. I thought MainConfig.rules was the ultimate override.

Hi. Quick answer, you need to use something like [...unjs({}), <your rules>] or unjs({}, ...your rules) the later ones overrides defaults. mainConfig overrides unjs rules only for convenience of usage across repos.

Thank you for clarifying the intended use of mainConfig, behaviour is less confusing now

Argument of type 'ConfigWithExtends' is not assignable to parameter of type 'TypedFlatConfig'.
  Types of property 'ignores' are incompatible.

^--- this might be the cause of the problem adding ignores

but if I use typescript-eslint's config() to type the rules instead of unjs() unbuild explodes 😭

https://github.com/poupe-ui/eslint-config/blob/pr-amery-next/src/config.ts <--- this branch illustrates how unbuild explodes when using unjsPreset and typescript-eslint's config() side by side. eslint using the files via jiti's stub works though.

it's a single commit from the version using only unjsPreset(), without rule types for options added from plugins and ignore problems, and one using tseslint's config() to type my rules next to unjsPreset(), which works for tsc --noEmit, eslint and vscode over unbuild --stub but exploding on unbuild.
