+# Copilot Instructions
+
+This is an E-commerce microservices architecture built with TypeScript in a Turborepo monorepo. Understanding the service patterns and communication flows is critical for effective development.
+
+## Architecture Overview
+
+### Microservices Structure
+- **auth-service** (port 8003) - Clerk authentication, user management
+- **product-service** (port 8000) - Product CRUD, Prisma/PostgreSQL 
+- **order-service** (port 8001) - Order management, MongoDB, Fastify
+- **payment-service** (port 8002) - Stripe payments, Hono framework
+- **email-service** - Kafka consumer for notifications
+
+### Frontend Applications
+- **client** (port 3002) - Customer Next.js app with Stripe integration
+- **admin** (port 3003) - Admin dashboard for management
+
+## Key Development Patterns
+
+### Authentication Flow
+All services use Clerk for auth. Services validate tokens via `@clerk/express` middleware:
+```typescript
+// Pattern: shouldBeUser/shouldBeAdmin middleware
+import { getAuth } from "@clerk/express";
+const auth = getAuth(req);
+req.userId = auth.userId;
+```
+
+### Service Communication
+Services communicate via Kafka events using `@repo/kafka` package:
+```typescript
+// Pattern: Event production
+producer.send("user.created", { value: { email, username } });
+
+// Pattern: Event consumption  
+consumer.subscribe([{
+  topicName: "order.created",
+  topicHandler: async (message) => { /* handle */ }
+}]);
+```
+
+### Database Patterns
+- **product-service**: Prisma client with **Neon PostgreSQL** (serverless)
+- **order-service**: Mongoose with **MongoDB Atlas Serverless**
+- **Shared types**: `@repo/types` for consistent data structures
+- **Connection handling**: Optimized for serverless with connection pooling
+
+### Serverless Database Configuration
+```typescript
+// Neon PostgreSQL - uses connection pooling automatically
+DATABASE_URL="postgresql://user:pass@ep-xxx.neon.tech/db?pgbouncer=true"
+DIRECT_URL="postgresql://user:pass@ep-xxx.neon.tech/db" // for migrations
+
+// MongoDB Atlas Serverless - optimized connection options
+MONGO_URL="mongodb+srv://user:pass@cluster.mongodb.net/db?retryWrites=true&w=majority"
+```
+
+### Development Commands
+
+```bash
+# Start all services in development
+pnpm dev
+
+# Start specific service
+turbo dev --filter=product-service
+
+# Database operations (from workspace root)
+pnpm --filter=@repo/product-db db:generate
+pnpm --filter=@repo/product-db db:migrate
+
+# Start Kafka cluster
+cd packages/kafka && docker-compose up
+```
+
+### Service Ports & URLs
+- product-service: 8000
+- order-service: 8001  
+- payment-service: 8002
+- auth-service: 8003
+- client: 3002
+- admin: 3003
+
+### Essential Environment Variables
+- `DATABASE_URL` - Neon PostgreSQL (with pgbouncer connection pooling)
+- `DIRECT_URL` - Neon PostgreSQL direct connection (for migrations)
+- `MONGO_URL` - MongoDB Atlas Serverless
+- `CLERK_SECRET_KEY` - Authentication
+- `STRIPE_SECRET_KEY` - Payments
+- `NEXT_PUBLIC_*_SERVICE_URL` - Service endpoints for frontends
+
+### Framework-Specific Notes
+- **auth/product-service**: Express.js with middleware patterns
+- **order-service**: Fastify with plugin registration
+- **payment-service**: Hono framework with different syntax
+- **Frontend apps**: Next.js 15 with App Router, server components for data fetching
+
+When working on services, always check the corresponding package.json for service-specific scripts and the utils/kafka.js file for event communication setup.

+# Environment Variables for Serverless Databases
+
+This project uses serverless databases for better scalability and cost efficiency.
+
+## PostgreSQL (Neon)
+
+### Required Environment Variables:
+```bash
+# Neon PostgreSQL Connection (with connection pooling)
+DATABASE_URL="postgresql://username:password@ep-xxx.us-east-1.aws.neon.tech/dbname?sslmode=require&pgbouncer=true&connect_timeout=15"
+
+# Direct URL for migrations (without connection pooling)
+DIRECT_URL="postgresql://username:password@ep-xxx.us-east-1.aws.neon.tech/dbname?sslmode=require"
+```
+
+### Neon Setup Steps:
+1. Create a Neon project at https://neon.tech
+2. Copy the connection string from Neon dashboard
+3. Use the pooled connection for `DATABASE_URL`
+4. Use the direct connection for `DIRECT_URL`
+
+## MongoDB (Atlas Serverless)
+
+### Required Environment Variables:
+```bash
+# MongoDB Atlas Serverless Connection
+MONGO_URL="mongodb+srv://username:password@cluster.xxxxx.mongodb.net/dbname?retryWrites=true&w=majority"
+```
+
+### MongoDB Atlas Serverless Setup Steps:
+1. Create a MongoDB Atlas account
+2. Create a new cluster and select "Serverless"
+3. Set up database user and network access
+4. Copy the connection string and replace credentials
+
+## Development vs Production
+
+### Development (.env.local):
+```bash
+# Development databases (can use smaller instances)
+DATABASE_URL="postgresql://dev_user:dev_pass@ep-dev.neon.tech/ecom_dev?sslmode=require&pgbouncer=true"
+DIRECT_URL="postgresql://dev_user:dev_pass@ep-dev.neon.tech/ecom_dev?sslmode=require"
+MONGO_URL="mongodb+srv://dev_user:dev_pass@dev-cluster.mongodb.net/ecom_dev?retryWrites=true&w=majority"
+```
+
+### Production (.env.production):
+```bash
+# Production databases (optimized for performance)
+DATABASE_URL="postgresql://prod_user:prod_pass@ep-prod.neon.tech/ecom_prod?sslmode=require&pgbouncer=true&connect_timeout=15"
+DIRECT_URL="postgresql://prod_user:prod_pass@ep-prod.neon.tech/ecom_prod?sslmode=require"
+MONGO_URL="mongodb+srv://prod_user:prod_pass@prod-cluster.mongodb.net/ecom_prod?retryWrites=true&w=majority"
+```
+
+## Database Operations
+
+### PostgreSQL (Prisma) Commands:
+```bash
+# Generate Prisma client
+pnpm --filter=@repo/product-db db:generate
+
+# Run migrations (uses DIRECT_URL)
+pnpm --filter=@repo/product-db db:migrate
+
+# Deploy to production
+pnpm --filter=@repo/product-db db:deploy
+```
+
+### MongoDB Operations:
+- MongoDB Atlas Serverless automatically handles scaling
+- No manual migration commands needed
+- Schema changes are handled at application level via Mongoose models
+
+## Benefits of Serverless Setup
+
+### Neon PostgreSQL:
+- **Auto-scaling**: Scales to zero when not in use
+- **Branching**: Create database branches for development
+- **Connection pooling**: Built-in PgBouncer for better performance
+- **Point-in-time recovery**: Automatic backups
+
+### MongoDB Atlas Serverless:
+- **Pay-per-use**: Only pay for operations and storage used
+- **Auto-scaling**: Automatically scales based on demand
+- **Global clusters**: Low latency worldwide
+- **Built-in security**: Encryption and network isolation
