A modern, type-safe Role-Based Access Control (RBAC) system built with TypeScript and functional programming principles. This monorepo provides a comprehensive solution for implementing robust permission systems in your applications.

The core RBAC system that provides the building blocks for permission management:

• Module and registry system
• Permission definitions and validation
• Extensible architecture for custom permission types

A powerful Domain Specific Language for building complex permission expressions with full type safety:

import { createExpression } from '@levi2ki/rbac-expression';
import { createModule, getDefaultRegistry, register } from '@levi2ki/rbac-core';
import { pipe } from 'fp-ts/function';
import * as Option from 'fp-ts/Option';

// Define permissions
enum UserPermissions {
    READ = 'READ',
    WRITE = 'WRITE',
    DELETE = 'DELETE',
    ADMIN = 'ADMIN',
}

enum TeamPermissions {
    MANAGE = 'MANAGE',
    VIEW = 'VIEW',
}

// Create registry
const registry = pipe(getDefaultRegistry(), register(createModule<UserPermissions>()('user')), register(createModule<TeamPermissions>()('team')));

// Create expressions
const { has, not, and, or } = createExpression(registry);

// Build complex permission logic
const canEditSensitiveData = and([has('user.WRITE'), or([has('user.ADMIN'), has('team.MANAGE')]), not('user.RESTRICTED')]);

// Evaluate against user context
const userContext = {
    user: Option.some([UserPermissions.WRITE, UserPermissions.ADMIN]),
    team: Option.some([TeamPermissions.VIEW]),
};

const result = canEditSensitiveData(userContext);
console.log(result); // true

✨ Key Features:

• Type-safe expressions with full TypeScript support
• Functional composition using Reader monads
• Composable operators (has, not, and, or)
• Performance optimized for large permission sets
• Zero runtime dependencies beyond core libraries

React hooks and components for seamless RBAC integration in React applications:

• usePermissions() hook for permission checking
• <PermissionGate> component for conditional rendering
• Context providers for permission management
• HOCs for higher-order component patterns

# Install the entire monorepo
pnpm add @levi2ki/rbac-core @levi2ki/rbac-expression

# Or install individual packages
pnpm add @levi2ki/rbac-core
pnpm add @levi2ki/rbac-expression

1. Set up your permission modules:

import { createModule, getDefaultRegistry, register } from '@levi2ki/rbac-core';

const registry = pipe(getDefaultRegistry(), register(createModule<UserPermissions>()('user')), register(createModule<TeamPermissions>()('team')));

1. Create expressions:

import { createExpression } from '@levi2ki/rbac-expression';

const { has, and, or } = createExpression(registry);

const canAccessAdminPanel = and([has('user.ADMIN'), or([has('user.SUPER_USER'), has('team.ADMIN')])]);

1. Evaluate permissions:

const userContext = {
    user: Option.some([UserPermissions.ADMIN]),
    team: Option.some([TeamPermissions.VIEW]),
};

const hasAccess = canAccessAdminPanel(userContext);
