IdOf

See source code

Utility type that extracts the ID type from a record type. This is useful when you need to work with record IDs without having the full record type.

type IdOf<R extends UnknownRecord> = R['id']

Example

interface Book extends BaseRecord<'book', RecordId<Book>> {
  title: string
  author: string
}

// Extract the ID type from the Book record
type BookId = IdOf<Book> // RecordId<Book>

function findBook(id: IdOf<Book>): Book | undefined {
  return store.get(id)
}
