Basic usage

See the Casbin adapters documentation for more information.

import { Knex } from "knex";

import { ObjectionAdapter } from "@willsoto/casbin-objection-adapter";

const knex = Knex({
  /* regular knex options */
});

// All configuration is optional
const adapter = await ObjectionAdapter.newAdapter(knex, {});

// Create the enforcer with the given model
const enforcer = await newEnforcer("basic_model.conf", adapter);

// Supports auto-save
// See: https://casbin.org/docs/en/adapters#autosave
enforcer.enableAutoSave(true);

// No need to save explicitly since auto-save is enabled
await enforcer.addPolicies([
  ["alice", "data1", "read"],
  ["bob", "data2", "write"],
]);

await enforcer.enforce("alice", "data1", "read"); // true
await enforcer.enforce("bob", "data1", "read"); // false
