I'm honestly surprised there aren't more projects like this
This is exactly what got us started - we are solving automatic REST-GraphQL API endpoint creation for all SQL databases. Check us out https://github.com/xgenecloud/xgenecloud
Authentication is also built in (currently only supports email/password, but more in the works). I implemented granular permissions for API routes that can be set via configuration really easily, which uses JWTs from the user login.
This is neat.
Does this mean - if your generator finds a new model in mongodb, it autogenerates model file within the folder and vice-versa it creates APIs if there is a new model file within model folder ?
