A more realistic example would be a decorator that can only be applied to const integer = <TKey extends keyof any, TTarget extends { [K in TKey]: number }>(
target: TTarget,
key: TKey
) => { /* ... */ };
class Foo {
@integer foo = 123;
@integer bar = "adsf"; // error:
} |

You can use const integer = <TKey extends PropertyKey , TTarget extends { [K in TKey]: number }>(
target: TTarget,
key: TKey
) => { /* ... */ };
class Foo {
@integer foo = 123;
@integer bar = "adsf"; // error:
} |

{ "rules": { "@typescript-eslint/no-explicit-any": 2 } }Currently, the expression
keyof anyis probably the only (sane) way of saying "a type of things that can be object keys". But it is disallowed underno-explicit-any.The long way of
string | number | symbolisn't portable enough because of thesymbolpart.Versions
