required property

[laszlo-zaptic]

how to make a property required? something like

    @property({required: true})
    placeholder: string

so that TS and/or runtime error appear if this property isn't set?

This is actually an existing lit-analyzer feature request: runem/lit-analyzer#74

i'm using the component with react also, and in @lit-labs/react this line seems to make every property and event optional

lit/packages/labs/react/src/create-component.ts

Line 134 in b8ceafb

Partial<Omit<I, 'children'>> &

would it make sense to define properties for the class as optional like

 @property()
 placeholder?: string

and then the properties (maybe also events) could be removed from the Partial<>?
