Prisma Adapter

NPM version NPM download Build Status Gitter

Prisma Adapter is the Prisma adapter for Node-Casbin. With this library, Node-Casbin can load policy from Prisma 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 Prisma website or other places.

Installation

npm install casbin-prisma-adapter --save

Getting Started

Append the following content to your schema.prisma:

model CasbinRule {
  id    Int     @id @default(autoincrement())
  ptype String
  v0    String?
  v1    String?
  v2    String?
  v3    String?
  v4    String?
  v5    String?
 
  @@map("casbin_rule")
}

Create table(MySQL):

CREATE TABLE IF NOT EXISTS `casbin_rule` (
  `id` int NOT NULL AUTO_INCREMENT,
  `ptype` varchar(255) DEFAULT NULL,
  `v0` varchar(255) DEFAULT NULL,
  `v1` varchar(255) DEFAULT NULL,
  `v2` varchar(255) DEFAULT NULL,
  `v3` varchar(255) DEFAULT NULL,
  `v4` varchar(255) DEFAULT NULL,
  `v5` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
);

Here is a simple example:

import casbin from 'casbin';
import { PrismaAdapter } from 'casbin-prisma-adapter';
 
async function main() {
  const a = await PrismaAdapter.newAdapter();
  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();
}
 
main();
