Sequelize Adapter

Sequelize Adapter is the Sequelize adapter for Node-Casbin. With this library, Node-Casbin can load policy from Sequelize supported database or save policy to it.

Based on Officially Supported Databases, the current supported databases are:

• PostgreSQL
• MySQL
• SQLite
• MSSQL

You may find other 3rd-party supported DBs in Sequelize website or other places.

Installation

NPM Install

npm install casbin-sequelize-adapter --save

Yarn Install

yarn add casbin-sequelize-adapter

Testing Locally

Start mysql for tests:

docker compose up -d

yarn test

Simple Example

import casbin from 'casbin';
import { SequelizeAdapter } from 'casbin-sequelize-adapter';

async function myFunction() {
  // Initialize a Sequelize adapter and use it in a Node-Casbin enforcer:
  // The adapter can not automatically create database.
  // But the adapter will automatically and use the table named "casbin_rule".
  // The second boolean argument: autoCreateTable determines whether the adapter will automatically create the "casbin_rule" table.
  // ORM should not create databases automatically.
  const a = await SequelizeAdapter.newAdapter(
    {
      username: 'root',
      password: '',
      database: 'casbin',
      dialect: 'mysql',
    },
    true,
  );

  const e = await casbin.newEnforcer('examples/rbac_model.conf', a);

  // Check the permission.
  e.enforce('alice', 'data1', 'read');

  // Modify the policy.
  // await e.addPolicy(...);
  // await e.removePolicy(...);

  // Save the policy back to DB.
  await e.savePolicy();
}
