I'm facing an issue with accessing a nested object key in my interface. In my scenario, I am able to access non-nested object keys in my parameter function, but the nested key seems inaccessible. Can anyone provide assistance on how to resolve this issue?
function myFunc<T extends object>(): {
watch: (type: keyof T) => void
} {
return { watch: () => {} }
}
interface Props {
name: string
age: number
height: {
ok: boolean
}
}
const { watch } = useForm<Props>()
watch('age')
Refer to this post for a list of possible solutions - Typescript: retrieving nested object keys
If you're looking for a solution tailored to your specific example, consider giving this a try:
type CombineKeys<K extends string, P extends string> = `${K}${"" extends P ? "" : "."}${P}`;
type ObjectPaths<T> = T extends object
? { [K in keyof T]-?: K extends string
? `${K}` | CombineKeys<K, ObjectPaths<T[K]>>
: never
}[keyof T]
: never
function createForm<T extends object>(): {
observe: (key: ObjectPaths<T>) => void
} {
return { observe: () => {} }
}
