Find an open-source project that has a react frontend and could use a tour, and create a PR for a nice tour using your library. Be transparent that you're the author of the library and you've done this work to showcase the capabilities of it.

I personally usually dislike that kind of tour and look for the skip button as soon as I can, so I'm not sure what sort of reception you'll see, so be prepared for it to be rejected. But then you can try again somewhere else (without getting spammy)

How are people supposed to have heard of it at all?

What’s their incentive to switching to an unknown OSS solution that may or may not be maintained in a year, from their current stable and maintained solution?

How can they be confident your code is safe and won’t intentionally or inadvertently open backdoors on their dev machine or introduce vulnerabilities to their app?

“If you build it, they will come” only works in the movies.

The readme shows signs of it being written by an LLM: the use of emojis and the lists mainly.

The readme might indicate the rest of the library might also be written by an LLM. I see there's a sprinkling of emojis in comments in the example code.

Marketing is hard.

I skipped past the demo link at the top the first time I scanned through it, it could be more visible.
