You can use "no-multi-spaces": "error",

[rhalaly]

I thought this rule should enforce multi spaces as well... But thank you

[vinaysharma14]

Could you elaborate on what you mean by multiline enforcement?

[rhalaly]

Sorry, typo :). Meant multi spaces enforcement...

[armano2]

this rule actually works as described in documentation and similarity to other spacing rules from eslint
spacing rules except no-multi-spaces and indent enforce no whitespace or at least one whitespace between tokens

https://eslint.org/docs/rules/template-curly-spacing
https://eslint.org/docs/rules/generator-star-spacing
https://eslint.org/docs/rules/array-bracket-spacing
etc..

hm... should this rule also error when there is more than 1 space? If that's the case, I could make a PR

[Josh-Cena]

I don't think this should even be accepting PRs @JoshuaKGoldberg? ESLint's spacing rules do not enforce the number of spaces anyways, since there's the no-multi-spaces rule.

[lonyele]

hm... so for this situation, extending no-multi-spaces(probably enhancement: new base rule extension tag) and cover type annotation is better?

[Josh-Cena]

That would be my thought, yeah

[JoshuaKGoldberg]

Oof, yes, sorry for marking this as accepting prs - that was incorrect of me. Thanks for the catch.
