UI elements in npm?

I really like the section about creating a small reusable widget in HTML. I wonder if people do that in practice and if one can find such packages in npm? @substack what's your experience? Do you write everything yourself everytime?

The issue refers to the handbook section about creating a small reusable widget in HTML and asks whether similar packages exist in npm. Start by reading that section and reviewing the question's context; the scope and completion criteria are not defined, so a maintainer would need to decide whether any documentation change is wanted.
