I do the same thing, but it doesn't play nicely with the modern JS ecosystem. I have a library of re-usable JS/HTML/CSS components that I can sling around at will. But I can't use them on React of Vue projects so easily.

One of the selling points of React/Vue was that components were portable. But I have seen so few people actually re-use anything in the real world and you didn't need a library to make re-usable components to begin with.

I believe that re-usability isn't a language or framework feature, it has to be a personal or team choice to prioritize it. It could be as simple as a utils folder or as organised as a bunch of modularized git repos but ultimately you have to choose to organise that way.
