# LynkedUp Platform
> Mobile-first SDK-based application suite with enterprise-grade security and offline-first capabilities
[![CI Status](https://github.com/lynkedup/monorepo/workflows/CI/badge.svg)](https://github.com/lynkedup/monorepo/actions)
[![License](https://img.shields.io/badge/License-Proprietary-red.svg)](LICENSE)
## 🏗️ Architecture Overview
LynkedUp is built as a **PNPM monorepo** with **Nx orchestration**, featuring:
- **📱 Mobile-First**: React Native applications with native security integrations
- **🔐 Security by Default**: Hardware-backed cryptography, DPoP, SQLCipher encryption
- **📴 Offline-First**: 100% functional offline with conflict-free synchronization
- **🎯 SDK-First Modularity**: Independent, composable SDKs with strict boundaries
- **🛡️ Policy-Aware**: Fine-grained ABAC via Permit.io/OPA
- **🏢 Multi-Tenant**: Organization-level encryption keys and data isolation

## 🚀 Quick Start
### Prerequisites
- Node.js 18+
- PNPM 8+
- React Native development environment
- Xcode (iOS) / Android Studio (Android)
### Installation
```bash
# Clone and install dependencies
git clone https://github.com/lynkedup/monorepo.git
cd lynkedup-monorepo
pnpm install
# Initialize development environment
pnpm nx run-many -t build
```
### Development
```bash
# Start SDK playground for development
pnpm dev:playground
# Start LynkedUp Pro app
pnpm dev:pro
# Run tests across all packages
pnpm test
# Run only affected tests (recommended)
pnpm affected:test
```

## 🔐 Security Features
- **Hardware-Backed Keys**: iOS Secure Enclave & Android StrongBox
- **DPoP Authentication**: RFC 9449 sender-constrained tokens
- **Contextual Encryption**: Organization-specific data encryption keys
- **Cryptographic Erasure**: Remote data destruction via key deletion
- **Device Attestation**: Apple DeviceCheck & Play Integrity integration
- **Policy-Driven Access**: Real-time ABAC enforcement
## 📴 Offline Capabilities
- **Local-First Storage**: Encrypted SQLCipher with reactive queries
- **Durable Outbox Pattern**: Reliable offline mutation queuing
- **CRDT Synchronization**: Conflict-free collaborative data
- **Optimistic UI**: Immediate feedback with eventual consistency
- **Policy Caching**: Local ABAC evaluation with server enforcement
## 🛠️ Development Workflow
### Module Boundaries
The monorepo enforces strict architectural boundaries via ESLint rules:
- **Domain Purity**: Domain layers cannot import infrastructure
- **Vertical Isolation**: Features cannot depend on other features
- **Layered Dependencies**: UI → Data → Domain → Shared
### SDK Development
Each SDK follows clean architecture principles:
1. **Domain Layer**: Pure TypeScript business logic
2. **Data Layer**: Infrastructure adapters (RxDB, GraphQL, native modules)
3. **UI Layer**: React Native components and screens
See individual SDK playbooks in `packages/*/README.playbook.md`.
### Testing Strategy
- **Unit Tests**: High coverage for business logic (Jest)
- **Contract Tests**: GraphQL schema compliance (MSW)
- **Integration Tests**: Cross-SDK interactions
- **E2E Tests**: Complete user flows (Detox)
## 📋 Available Scripts

## 🚢 Release Management
This monorepo uses [Changesets](https://github.com/changesets/changesets) for versioning and publishing:
1. **Create Changeset**: `pnpm changeset`
2. **Version Bump**: `pnpm changeset:version`
3. **Publish**: `pnpm changeset:publish`
Only SDK packages are published to NPM. Applications are deployment artifacts.
## 🧪 CI/CD Pipeline
- **SLSA Level 3**: Supply chain security with signed provenance
- **Nx Cloud**: Remote caching for optimal build performance
- **Affected Testing**: Only test/build changed packages
- **Semantic Versioning**: Automated version management
- **Security Scanning**: Dependency and code vulnerability checks
## 📚 Documentation
- **Architecture**: [docs/architecture.md](docs/architecture.md)
- **Security Model**: [docs/security.md](docs/security.md)
- **SDK Playbooks**: `packages/*/README.playbook.md`
- **API Reference**: Generated from TypeScript types
- **GraphQL Schema**: `apps/api-bff/schema.graphql`
## 🤝 Contributing
1. **Create Feature Branch**: `git checkout -b feat/scope-description`
