npm install casequelize

Simple Example

const Adapter = require('casequelize');
const { Enforcer } = require('casbin');

module.exports = () => {
    // Initialize a Sequelize adapter and use it in a Casbin enforcer:
    // The adapter will use the MySQL database named "casbin".
    // If it doesn't exist, the adapter will create it automatically.
  const adapter = await Adapter.newAdapter('mysql://root:123456@localhost:3306/casbin', {}); // Your driver and data source.
  const enforcer = await Enforcer.newEnforcer('examples/rbac_model.conf', adapter);
    // Or you can use an existing DB "abc" like this:
    // The adapter will use the table named "casbin_rule".
    // If it doesn't exist, the adapter will create it automatically.
    // adapter = sequelizeadapter.newAdapter("mysql", "mysql_username:mysql_password@tcp(", true)

    // Load the policy from DB.
    await enforcer.loadPolicy()
    // Check the permission.
    await enforcer.enforce('alice', 'data1', 'read')
    // Modify the policy.
    // e.addPolicy(...)
    // e.removePolicy(...)
    // Save the policy back to DB.
    await enforcer.savePolicy()
