💻 Code
type SingleOrArray<T> = T | readonly T[];
type ProvidedActor = {
src: string;
input?: unknown;
};
type MachineConfig<TActors extends ProvidedActor> = {
invoke?: SingleOrArray<TActors>;
};
declare function setup<TActors extends ProvidedActor>(): {
createMachine: (config: MachineConfig<TActors>) => void;
};
setup<{ src: "fetchUser"; input: string }>().createMachine({
invoke: {
src: "fetchUser",
input: 10,
},
});🙁 Actual behavior
invoke property gets highlighted
🙂 Expected behavior
input property should get highlighted as it's the one that it's not correct and it's more specific than invoke
Additional information about the issue
we can observe the error location to change when:
- we remove optionality from
invoke - we make the provided type argument a union
