NPM version NPM download codebeat badge Build Status Coverage Status Gitter

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

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


npm install casbin-sequelize-adapter --save

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 will use the MySQL database named "casbin".
    // If it doesn't exist, the adapter will create it automatically.
    const a = await SequelizeAdapter.newAdapter('mysql://root:123@localhost:3306/'); // Your connection string. 

    // 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.
    // const a = await SequelizeAdapter.newAdapter('mysql://root:123@localhost:3306/abc', true);

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

    // Load the policy from DB.
    await e.loadPolicy();

    // 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();
