Pretty primitive rendering limited to horizontal text. However, it does render to plain HTML which might be an advantage in some contexts. In my experience React components integrate poorly with their hosts (in particular, they do not expose "instances" which can be used to expose an API. From here I'll be skipping any other React solutions.

As well as rendering to plain HTML, it can also deal with different text directions, although the layout algorithm in the demo seems a little buggy and the default rendering isn't very "wordle-y". My impression is that the words list cannot be updated and the code and packaging appear amateurish.
