## Overview

This monorepo provides a complete platform for MotorMetrics, tracking Singapore's car registration statistics and Certificate of Entitlement (COE) data. The system includes:

- **Web Application**: Next.js 16 frontend with Cache Components, co-located route components, enhanced homepage featuring latest COE results, interactive charts, analytics, AI-generated blog content, and integrated admin interface at `/admin` path. Also hosts the data updater workflows.
- **Integrated Data Updater**: Vercel WDK workflow-based system for fetching and processing LTA data (consolidated into web application)
- **LLM Blog Generation**: Automated blog post creation using Vercel AI SDK with Google Gemini for market insights (runs within web workflows)
- **Social Media Integration**: Automated posting to Discord, LinkedIn, Telegram, and Twitter with trackable redirect routes (triggered by web workflows)
- **MCP Server**: Published npm package for blog post CRUD operations via Claude Code
- **Documentation Site**: Fumadocs-powered documentation for technical guides and API reference
- **Infrastructure**: Vercel deployment with automatic CI/CD

## Getting Started

### Prerequisites

- Node.js >= 22
- pnpm v11.0.0

### Installation

```bash
# Clone the repository
git clone https://github.com/motormetrics/motormetrics.git
cd motormetrics

# Install dependencies
pnpm install
```

#### Dependency Management

This project uses **pnpm catalog** for centralised dependency version management. Shared dependencies (React, Next.js, TypeScript, testing tools, etc.) are defined in `pnpm-workspace.yaml` and referenced by workspace packages using the `catalog:` protocol.

**Key catalog packages:**
- React ecosystem: `react` (^19.2.3), `react-dom` (^19.2.3), `next` (^16.1.0)
- TypeScript & types: `typescript` (^5.8.3), `@types/node` (^22.16.4), `@types/react` (^19.2.0), `@types/react-dom` (^19.2.0)
- Testing tools: `vitest` (^4.0.15), `@vitest/coverage-v8` (^4.0.15)
- AI & LLM: `ai` (^6.0.1), `@ai-sdk/google` (^3.0.6), `@langfuse/otel` (^4.4.2)
- Utilities: `date-fns` (^3.6.0), `zod` (^4.1.13), `sonner` (2.0.7)

**Root-level dependencies** (not in catalog):
- Build tools: `turbo` (^2.6.3)
- Code quality: `@biomejs/biome` (2.3.0), `husky` (^9.1.7), `lint-staged` (^16.1.5)
- Release management: `semantic-release` (^24.0.0)

This ensures version consistency across all workspace packages and simplifies dependency upgrades.
