Quick Start

Prerequisites

• Docker Engine 24+ & Docker Compose v2
• Node.js 22 LTS
• pnpm 10.27+ (corepack enable && corepack prepare pnpm@latest --activate)

Setup

# 1. Clone the repository
git clone <repo-url> && cd goodgo-platform-ai

# 2. Copy environment file
cp .env.example .env

# 3. Start infrastructure services
docker compose up -d

# 4. Verify services are healthy
docker compose ps

# 5. Install dependencies
pnpm install

# 6. Generate Prisma client
pnpm db:generate

# 7. Run database migrations
pnpm db:migrate:dev

# 8. Seed the database (optional)
pnpm db:seed

# 9. Start all apps in dev mode
pnpm dev

The API will be available at http://localhost:3001/api/v1 and the web app at http://localhost:3000.

Swagger UI: Open http://localhost:3001/api/v1/docs for interactive API documentation.
