# Panda Monorepo

**Status**: 🚧 **Placeholder - Under Planning**  
**Purpose**: Unified monorepository for all Panda ecosystem projects with shared code, tooling, and unified dependency management.

**Note**: PANDA (Pan-African Network for Digital Advancement) is a partner in **PanTel**, a telecommunications joint venture with Sankofa. The panda_monorepo organizes PANDA-related projects.

---

## Overview

The Panda Monorepo consolidates all Panda ecosystem projects into a single, unified repository structure. This enables shared code, unified versioning, simplified dependency management, and coordinated development across all Panda initiatives.

---

## Purpose

The monorepo structure provides:

- **Unified Development**: Single repository for all Panda projects
- **Shared Libraries**: Common code, types, and utilities across projects
- **Dependency Management**: Unified versioning and dependency resolution
- **Cross-Project Refactoring**: Easier refactoring across project boundaries
- **Coordinated Releases**: Unified versioning and release process
- **Shared Tooling**: Common build, test, and deployment tools
- **Simplified CI/CD**: Single pipeline for all projects

## Submodules & Projects (Planned)

### Documentation (Submodule)

| Submodule | Path | Description | Status |
|-----------|------|-------------|--------|
| **pan-tel** | `packages/pan-tel` or `apps/pan-tel` | Telecommunications project | 🚧 Placeholder |
| **panda_docs** | `docs/panda-docs` | Documentation repository | 🚧 Placeholder |

**Note**: 
- The `pan-tel` project content is currently archived in `loc_az_hci` under an archive beginning with `6g_gpu*`. The project directory serves as a placeholder until the archive is unpacked and integrated.
- PanTel is a **joint venture** between Sankofa and PANDA (Pan-African Network for Digital Advancement).

### Projects (To Be Added)

Projects in the Panda ecosystem will be integrated as submodules or packages. Specific projects are to be determined.

---

## Package Manager & Tooling

### Recommended: pnpm Workspaces + Turborepo

**Benefits:**
- Fast installs with pnpm
- Build caching with Turborepo
- Task orchestration
- Dependency graph optimization

### Alternative: Nx

**Benefits:**
- Comprehensive monorepo tooling
- Advanced dependency graph
- Code generation
- Testing and building

### Configuration Example (pnpm + Turborepo)

```yaml
# pnpm-workspace.yaml
packages:
  - 'packages/*'
  - 'apps/*'
  - 'tools/*'
```

```json
// turbo.json
{
  "pipeline": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": ["dist/**", "build/**"]
    },
    "test": {
      "dependsOn": ["build"],
      "outputs": ["coverage/**"]
    },
    "lint": {},
    "type-check": {}
  }
}
```

---

## Shared Packages (Planned)

### panda-shared
**Purpose**: Common utilities and types shared across all Panda projects

**Contents:**
- TypeScript type definitions
- Utility functions
- Configuration helpers
- Constants and enums
- Validation schemas

### panda-api-client
**Purpose**: Type-safe API clients for Panda services

**Contents:**
- REST API clients
- GraphQL clients
- WebSocket clients
- Type definitions for API responses

### panda-schemas
**Purpose**: Shared data schemas and validation

**Contents:**
- JSON schemas
- GraphQL schemas
- Prisma schemas (if applicable)
- Zod validation schemas

### panda-auth
**Purpose**: Shared authentication and authorization

**Contents:**
- Auth utilities
- Token management
- Permission checking
- Session management

---

## Development Workflow (Planned)

### Setup

```bash
# Clone monorepo
git clone <monorepo-url>
cd panda_monorepo

# Initialize submodules
git submodule update --init --recursive

# Install dependencies
pnpm install

# Build all packages
pnpm build

# Run tests
pnpm test
```

### Adding a New Package

```bash
# Create new package
mkdir -p packages/my-package
cd packages/my-package

# Initialize package
pnpm init

# Add to workspace (already configured in pnpm-workspace.yaml)

# Install dependencies
pnpm add <dependency>

# Build
pnpm build
```

### Working with Submodules

```bash
# Update all submodules
git submodule update --remote

# Add new submodule
git submodule add <repository-url> packages/panda-new-project

# Commit submodule updates
git add .gitmodules packages/panda-new-project
git commit -m "Add panda-new-project submodule"
```

### Building and Testing

```bash
# Build all packages
pnpm build

# Build specific package
pnpm --filter @panda/shared build

# Run all tests
pnpm test

# Run tests for specific package
pnpm --filter @panda/shared test

# Type check all packages
pnpm type-check

# Lint all packages
pnpm lint
```

---

## CI/CD Pipeline (Planned)

### Workflow Structure

1. **Lint & Type Check**: Run on all packages
2. **Unit Tests**: Run package-specific tests
3. **Integration Tests**: Run cross-package tests
4. **Build**: Build all packages
5. **E2E Tests**: Run end-to-end tests
6. **Deploy**: Deploy based on changed packages

### Turborepo Pipeline

```yaml
# .github/workflows/ci.yml (example)
- Build packages (cached)
- Test packages (cached)
- Type check (cached)
- Lint (cached)
- Integration tests
- E2E tests
- Build Docker images (for applications)
- Deploy (staging/production)
```

---

## Versioning Strategy

### Option 1: Independent Versioning
- Each package has its own version
- Semantic versioning per package
- Useful for submodules approach

### Option 2: Unified Versioning
- Single version for monorepo
- All packages versioned together
- Easier for coordinated releases

**Recommendation**: Start with independent versioning, consider unified for major releases.

---

## Dependency Management

### Shared Dependencies

Common dependencies should be hoisted to root:

```json
// package.json (root)
{
  "devDependencies": {
    "typescript": "^5.0.0",
    "@types/node": "^20.0.0",
    "eslint": "^8.0.0",
    "prettier": "^3.0.0"
  }
}
```

### Package-Specific Dependencies

Package-specific dependencies in package.json:

```json
// packages/panda-shared/package.json
{
  "dependencies": {
    "zod": "^3.22.0"
  }
}
```

---

## Documentation Structure

### Monorepo-Level Documentation

- Development setup
- Contribution guidelines
- Release process
- CI/CD documentation

### Package-Level Documentation
Each package maintains its own:

- Changelog

### Documentation Submodule
### Documentation Submodule
- **[panda_docs](../panda_docs/)** - Documentation repository (submodule)
  - Integrated documentation site
  - API documentation generation
