The work that both Roy and yourself have put into SQLite in the browser is awesome, there are so many exciting things coming that are going to be built on top of it. Thank you!
It does seem to suffer from maintainer problems too though, and I don't blame Roy Hashimoto for that. I wouldn't want to maintain such an obvious wrapper when it should be a task for SQLite's team to upstream the changes.
Roy Hashimoto doesn't want to maintain it as an NPM package for instance, as it is just an experiment: https://github.com/rhashimoto/wa-sqlite/issues/12
