Further, what is it? Maybe I'm not a very good reader, but after looking at the website multiple times I'm not at all sure what RedwoodJS is. Comments here suggest it is some sort of React framework ...?
It is indeed a web app framework, based on React, GraphQL, Prisma, Storybook, Jest, and with many integrations for auth, logging, etc.
I didn't. Thank you! It would be nice if this information was on the link posted to HN though, or maybe the link should be changed to something more clear.
