Knex Adapter

Knex Adapter for Node-Casbin. Use this library for policy storage in Casbin.

For full database support list, go to the Knex documentation.

WARNING: This adapter has only been tested manually. It lacks automated tests, which will show up when I'll have time. If you want to use it in production - be careful.

Installation

npm install casbin-knex-adapter --save

yarn add casbin-knex-adapter

const casbin = require('casbin');

      port: 5432,
      user: 'user',

  // Create casbin enforcer
  const enforcer = await casbin.newEnforcer('model.conf', adapter);
