This is bit confusing for me - why there is private/data json's containing data, when this should be stored in the database ? For example, in the Swag shop demo, what if there is already Shops or Products in db, whats the point of the json's ?
Rest assured, they aren't used as long as you have products/shop settings etc already in place. If you want to see/edit the actual data past the first startup, connect to Mongo with mongo --port 3001 while Reaction is running.
Thank for reporting! I'm not sure the Swag shop has yet been updated for Reaction 1.11. Would need someone else to confirm though.
