修复警告

Use async .hasTable to check if table exists and then use plain .createTable. Since .createTableIfNotExists actually just generates plain "CREATE TABLE IF NOT EXIST..." query it will not work correctly if there are any alter table queries generated for columns afterwards. To not break old migrations this function is left untouched for now, but it should not be used when writing new code and it is removed from documentation.

• [x] mysql
• [x] mysql2
• [x] sqlite3
• [ ] oracledb

Installation

npm i casbin-basic-adapter

Simple Example

import { newEnforcer } from 'casbin';
import { Client } from 'pg';
import { BasicAdapter } from 'casbin-basic-adapter';

async function myFunction() {
  // Initialize a Basic 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".
  const a = await BasicAdapter.newAdapter('pg',
    new Client({
      user: 'postgres',
      database: 'postgres',
      password: 'postgres',
    }));

  const e = await 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();
