Maybe we could take a look at adding https://github.com/nuxt/eslint-config instead.

There has not yet been a response from a team member here: nuxt/eslint-plugin-nuxt#173,
but it looks more complete and active. It is however still under heavy development.

https://github.com/nuxt/eslint-config also solves some issues I've had to fix for #681. These redundant fixes can then be removed from eslint-config-hardcore. It also adds some more tweaks I did not think of before.

I do think this might lead to needing to have seperate a config for Nuxt. This could of course extend the existing hardcore/vue config.

We can't use nuxt/eslint-config because it extends eslint:recommended and @typescript-eslint/eslint-recommended, which would override rules from hardcore and hardcore/ts. But we could copy tweaks from nuxt/eslint-config to hardcore/vue.

I would prefer to have a single hardcore/vue config, but if there are significant differences between Vue.js and Nuxt, we could consider creating hardcore/nuxt config. I think I would prefer it to be an additional config (that doesn't extend hardcore/vue), so for a Nuxt project you would need to use "extends": ["hardcore", "hardcore/ts", "hardcore/vue", "hardcore/nuxt"].

@EvgenyOrekhov You're right. I overlooked that one. I will try to take a look at this (and #589) in the coming weeks.

eslint-plugin-nuxt still hasn't had any updates. It might be a better idea to copy some tweaks from https://github.com/nuxt/eslint-config. I will take a look at that this week.
