Detect typos in nuxt.config

[pi0]

Ref: nuxt/framework#5294 (comment)_

We added support for [key: string]: any] in nuxt.config since 1) some modules might not have provided types and 2) making easier during module development to not have errors before stubbing

But this seems having a negative DX effect as increases chance of unnoticed typos in config file.

I think we shall try making it strict again...

Maybe we could somehow provide a way to "losen up" the config interface to ensure typechecking would not fail for libs without types. I'm not a TS guru, but maybe something like this?

declare namespace Nuxt {
    interface NuxtConfig {
        someModule: any;
    }
}

Vote for strict. It's pretty easy to suppress error with ts-expect-error during module development.
