@objectql/plugin-security - Implementation Summary

Overview

Successfully implemented a comprehensive security plugin for the ObjectQL framework that provides Role-Based Access Control (RBAC), Field-Level Security (FLS), and Row-Level Security (RLS) following the @objectstack/spec protocol.

Implementation Status: ✅ COMPLETE

All required components have been implemented, documented, and reviewed.

Package Details

  • ✅ Security-hardened formula evaluation

PermissionGuard (src/permission-guard.ts)

  • ✅ Object-level permission checks (create, read, update, delete)
  • ✅ Field-level permission checks
  • ✅ Record-level permission checks
  • ✅ Row-level security checks
  • ✅ Permission result caching with TTL
  • ✅ Bitmask-based O(1) permission lookups

QueryTrimmer (src/query-trimmer.ts)

  • ✅ Row-level security filter injection
  • ✅ AST-level query modifications
  • ✅ Record rule to filter conversion
  • ✅ MongoDB-style filter generation

Integration Requirements

To integrate this plugin into an ObjectQL application:

  1. Install Dependencies

    pnpm install

  2. Import and Register

    import { ObjectQLSecurityPlugin } from '@objectql/plugin-security';

const kernel = createKernel({
  plugins: [
    new ObjectQLSecurityPlugin({
      enabled: true,
      permissions: [...],
      // ... config
    })
  ]
});

  3. Define Permissions

    const permissions: PermissionConfig = {
  name: 'project_permissions',
  object: 'project',
  object_permissions: { ... },
  // ... permission rules
};

Next Steps for Production

Testing (Recommended)

  • Add unit tests for each component
  • Add integration tests with ObjectQL
  • Add performance benchmarks
  • Add security penetration tests

Enhancements (Future)

  • Implement Redis storage backend
  • Implement database storage backend
  • Add permission inheritance
  • Add time-based permissions
  • Create admin UI for permission management
  • Add built-in metrics and monitoring

Documentation (Optional)

  • Add to ObjectQL documentation site
  • Create video tutorial
  • Write blog post about security architecture
  • Create migration guide from other security solutions
