class Base {}

const NameMixin = Mixin(<T extends Constructor>(superclass: T) => class extends superclass { name = "Node" })

const IdMixin = Mixin(<T extends Constructor>(superclass: T) => class extends superclass { id = nanoid() })

class MyClass extends mix(Base).with(NameMixin, IdMixin) {}

console.log(new MyClass()) // MyClass { name: 'Node', id: '2FHGySBlhFAMRwkiMiU9D' }

Instance of

type NameMixinType = MixinType<typeof NameMixin>
type IdMixinType = MixinType<typeof IdMixin>

type UserType = NameMixinType & IdMixinType

class User extends mix(Base).with(NameMixin, IdMixin) implements UserType {}
