There are a few tutorials and multiple different codebases for next.js and Auth0 integrations, but the repos are stale and honestly looking abandoned. I can’t build a product based on this. Is next.js a priority for Auth0?
The Auth0 support for Angular is first class and I guess that’s the platform I will go with. i feel that next.js is a pretty serious player though, and they even have an auth0 example in their repo (but another half-baked demo). This seems to be a gap in the Auth0 lineup.
