Primitives for extensible React datepicker components
All the primitives to build your own datepicker component.
Today if you need a datepicker component, there are tons to choose from. But each come with their own visual language. You're in luck if you use one of the popular UI frameworks, but if you have your own design system, you have to write a ton of CSS to make it look like one of your own, and you can't use your own components.
I encountered this problem and tried to build a datepicker component that doesn't enforce how it will look, but how it will behave. It uses the popular render props pattern to run the business logic and give you the necessary information to draw it using your own components, styling solution etc.
