Setup database

casibase will store its users, nodes and topics informations in a MySQL database named: casibase, will create it if not existed. The DB connection string can be specified at: https://github.com/casbin/casibase/blob/master/conf/app.conf

Casnode uses XORM to connect to DB, so all DBs supported by XORM can also be used.

  casdoorApplication = "app-casibase"
  

• Frontend (casibase\web\src\Conf.js)
