Properly defer resolution of mapped types with generic as clauses #51050

Merged
merged 4 commits into from Oct 7, 2022

This PR properly defers resolution of mapped types with as clauses that reference other type parameters than the iteration type parameter. The PR furthermore improves normalization of template literal and string mapping types (see baseline changes for examples).

Fixes #50558.

Is this correct for if xxx becomes number?

The string mapping types are all constrained to string, so xxx can't be number. It could however be `${number}`.

return true;
}
// A mapped type is generic if the as clause references other generic types than the iteration type.
// To determine this, we substitute the constraint type (that we now know isn't generic) for the iteration

If you're ever mapping on an empty type, you will end up with never in some cases, which may make the as clause never, making the mapped type not generic. This means that if an interface is intended to be merged with other interfaces, this will return different answers pre-merged vs. post-merged. At the very least, we should have a test for that.

interface Events {
    // empty for now
}

type OnOffEvents<K extends "on" | "off"> = {
    [P in keyof Events as `${K}${P}`]: (event: Events[P]) => void
};

If OnOffEvents is intended to be generic, should we consider just instantiating the mapped type variable with the string literal type "" instead?

I don't think any special handling is needed here. isGenericMappedType is supposed to determine whether the given type can possibly be affected by instantiation. When a mapped type maps over an empty object type, no further instantiation will affect the type (regardless of its as clause), so it is fine to say the type is non-generic. You're right that merging declarations may change the outcome here, but that'll change many other things too.

Tests and performance all look good. I think this is ready to merge.

Seems correct, though it would be ideal to add a test with an empty object type to exercise the edge case.
