• Python 3.12+ with virtual environment
• Node.js 20+
• pnpm installed globally
• .env files configured with necessary secrets

Quick Start

cd /Users/sd9235/code/mygh/learning_voice_ai_agent

Manual Service Startup

If the script doesn't work, start services manually:

1. Common Platform Services

cd /Users/sd9235/code/mygh/learning_ai_common_plat

# Growth Service
cd services/growth-service
pnpm install
pnpm dev > /Users/sd9235/code/mygh/learning_voice_ai_agent/.logs/growth-service.log 2>&1 &

# Billing Service
cd ../billing-service
pnpm install
pnpm dev > /Users/sd9235/code/mygh/learning_voice_ai_agent/.logs/billing-service.log 2>&1 &

# Platform Service
cd ../platform-service
pnpm install
pnpm dev > /Users/sd9235/code/mygh/learning_voice_ai_agent/.logs/platform-service.log 2>&1 &

# Tracker Service
cd ../tracker-service
pnpm install
pnpm dev > /Users/sd9235/code/mygh/learning_voice_ai_agent/.logs/tracker-service.log 2>&1 &

2. Voice Agent Services

cd /Users/sd9235/code/mygh/learning_voice_ai_agent

# Backend API
cd backend
source ../.venv/bin/activate
python -m uvicorn src.main:app --reload --host 0.0.0.0 --port 8000 > ../.logs/backend.log 2>&1 &

# Admin Dashboard
cd ../admin-dashboard-web
npm install
npm run dev > ../.logs/admin-dashboard.log 2>&1 &

# User Dashboard
cd ../user-dashboard-web
npm install
npm run dev > ../.logs/user-dashboard.log 2>&1 &

# Tracker Dashboard
cd ../tracker-dashboard-web
npm install
npm run dev > ../.logs/tracker-dashboard.log 2>&1 &

Environment Setup

Required Environment Files

1. Root .env (learning_voice_ai_agent)

   COSMOS_ENDPOINT=https://...
   COSMOS_KEY=...
   COSMOS_DATABASE=lysnrai
   JWT_SECRET=...
   AZURE_SPEECH_KEY=...
   AZURE_SPEECH_REGION=eastus
   AZURE_OPENAI_ENDPOINT=...
   AZURE_OPENAI_KEY=...
   AZURE_OPENAI_DEPLOYMENT=gpt-4o-mini
   

2. Dashboard .env.local files

   # admin-dashboard-web/.env.local
   COSMOS_ENDPOINT=https://...
   COSMOS_KEY=...
   JWT_SECRET=...
   NEXT_PUBLIC_APP_URL=http://localhost:3001
   
   # user-dashboard-web/.env.local
   COSMOS_ENDPOINT=https://...
   COSMOS_KEY=...
   JWT_SECRET=...
   NEXT_PUBLIC_APP_URL=http://localhost:3002

   TRACKER_API_URL=http://localhost:4004
   PLATFORM_API_URL=http://localhost:4003
   JWT_SECRET=...
   

Log Management

# View all logs in real-time
tail -f .logs/*.log

# View specific service log
tail -f .logs/backend.log

# Search logs for errors
grep -i "error\|exception\|failed" .logs/*.log

# Clear all logs
> .logs/backend.log .logs/growth-service.log .logs/billing-service.log \
  .logs/platform-service.log .logs/tracker-service.log \
  .logs/admin-dashboard.log .logs/user-dashboard.log .logs/tracker-dashboard.log

Stop Services

# Stop all services at once
./run-local-all-services.sh stop

# Or manually kill processes
pkill -f "uvicorn src.main:app"
pkill -f "next dev"
pkill -f "tsx.*src/server.ts"

Common Issues

Port Already in Use

# Find process using port
lsof -i :8000

# Kill it
kill -9 <PID>

# Or use this script to kill all dev ports
./run-local-all-services.sh stop

Service Won't Start

1. Check the log file: tail .logs/<service>.log
2. Verify environment variables are set
3. Ensure dependencies are installed
4. Check if required ports are available

Dashboard Can't Connect to Services

1. Verify services are running: ./run-local-all-services.sh status
2. Check CORS configuration in services
3. Verify API URLs in dashboard .env.local files

Development Tips

• Use the script - ./run-local-all-services.sh handles process management and logging
• Check logs first - Most issues have clear error messages in the logs
• Restart individual services - No need to restart everything unless there's a dependency issue
• Hot reload - All services support hot reload for fast development
• Use health endpoints - Quick way to verify services are responding
