🎉 Local Hosting Setup - Complete!

✅ What Was Implemented

1. Automated Backend Runner

File: scripts/run_local_backend.sh

  • ✅ Activates Python virtual environment
  • ✅ Checks Qdrant connection (Docker)
  • ✅ Checks Ollama models (Mixtral + Qwen)
  • ✅ Starts FastAPI on 0.0.0.0:8000
  • ✅ Verifies server is reachable
  • ✅ Shows helpful error messages with fixes

2. Public Tunnel Setup

File: scripts/setup_tunnel.sh

  • ✅ Supports Ngrok (quick testing)
  • ✅ Supports Cloudflare Tunnel (stable, free)
  • ✅ Interactive menu to choose provider
  • ✅ Automatic URL detection
  • ✅ Clear instructions for Netlify setup

3. One-Command Setup

File: scripts/start_everything.sh

  • ✅ Starts/checks Qdrant
  • ✅ Checks Ollama + models
  • ✅ Starts backend
  • ✅ Creates tunnel
  • ✅ Shows all URLs and PIDs
  • ✅ Complete automation

4. Service Verification

File: scripts/test_services.sh

  • ✅ Tests Qdrant connectivity
  • ✅ Tests Ollama + model availability
  • ✅ Tests backend health endpoint
  • ✅ Color-coded status output

5. CORS Security

File: backend/app.py

  • ✅ Restricted to specific domains only
  • ✅ Supports Netlify production
  • ✅ Supports localhost development
  • ✅ Supports Ngrok tunnels
  • ✅ Supports Cloudflare tunnels
  • ✅ NO wildcard CORS in production

6. Frontend Environment Support

File: .env.local.example

  • ✅ Example configuration provided
  • ✅ NEXT_PUBLIC_API_URL properly used
  • ✅ Fallback to localhost:8000
  • ✅ Clear instructions for tunnel URLs

7. Complete Documentation

Files:

  • docs/local_hosting.md - 500+ line comprehensive guide
  • docs/QUICKSTART.md - Quick reference cheat sheet
  • README.md - Updated with local hosting info

🚀 How to Use

Quick Start (One Command)

./scripts/start_everything.sh

Manual Start (Individual Services)

# Terminal 1: Qdrant
docker start qdrant

# Terminal 2: Ollama
ollama serve

# Terminal 3: Backend
./scripts/run_local_backend.sh

# Terminal 4: Tunnel
./scripts/setup_tunnel.sh

Test Everything

./scripts/test_services.sh

📋 Service Checklist

When everything is running, you should see:

🔧 Configuration Steps

1. Start Local Services

./scripts/start_everything.sh

2. Copy Your Tunnel URL

From the script output, copy the HTTPS URL:

https://abc123.ngrok-free.app

3. Set in Netlify

  1. Go to: https://app.netlify.com/sites/assistantstudy
  2. Site settings → Environment variables
  3. Add/Update:
    • Key: NEXT_PUBLIC_API_URL
    • Value: https://abc123.ngrok-free.app
  4. Trigger deploy

4. Verify

  1. Open: https://assistantstudy.netlify.app
  2. Check JARVIS status indicator
  3. Should show: "AI ONLINE" 🟢
  4. Try asking a question

🎯 What This Achieves

✅ Problem Solved

  • Backend runs on your laptop (full AI power)
  • Qdrant stores your materials locally
  • Ollama provides free AI inference
  • Public HTTPS URL for Netlify frontend
  • No cloud costs for backend
  • Full control over your data

✅ Security

  • CORS restricted to known domains
  • No public wildcard access
  • Tunnel provides HTTPS encryption
  • Local services not exposed directly

✅ Flexibility

  • Choose Ngrok (quick testing)
  • Or Cloudflare (stable, permanent)
  • Switch between tunnel providers
  • No code changes needed

✅ Automation

  • One-command setup
  • Auto-detection of services
  • Helpful error messages
  • No manual configuration

🔐 Security Features

CORS Configuration

ALLOWED_ORIGINS = [
    "http://localhost:3000",
    "https://assistantstudy.netlify.app",
    "https://*.ngrok-free.app",
    "https://*.trycloudflare.com",
]

What's Protected

  • ✅ Only specific domains allowed
  • ✅ Regex for tunnel subdomains
  • ✅ Credentials enabled for cookies
  • ✅ All HTTP methods allowed (within CORS)
  • ✅ Custom frontend URL support via env var

🎉 Result

Before

  • ❌ Manual service startup
  • ❌ No public access
  • ❌ Hardcoded URLs
  • ❌ No CORS configuration
  • ❌ Complex setup process

After

  • ✅ Automated service checks
  • ✅ Public HTTPS tunnel
  • ✅ Environment-based URLs
  • ✅ Secure CORS setup
  • ✅ One-command deployment

🚀 Next Steps

For You

  1. Run ./scripts/start_everything.sh
  2. Copy the tunnel URL
  3. Set in Netlify environment variables
  4. Deploy and test!

Optional Enhancements

  • Add systemd service for auto-start on boot
  • Create Docker Compose for all services
  • Add monitoring/alerting
  • Set up backup for Qdrant data
  • Configure static Ngrok domain (paid)

💡 Pro Tips

  1. Keep terminals organized: Use tmux or terminal tabs
  2. Monitor resources: Ollama uses GPU if available
  3. Backup Qdrant: Data persisted in Docker volume
  4. Use Cloudflare for long sessions: More stable than Ngrok
  5. Check logs: Each service shows real-time logs in terminal

📞 Support

If you encounter issues:

  1. Run diagnostics:

    ./scripts/test_services.sh

  2. Check service logs:

    • Backend: Terminal output
    • Qdrant: docker logs qdrant
    • Ollama: Terminal output

  3. Review documentation:

  4. Common fixes:

    • Port in use: lsof -ti:8000 | xargs kill -9
    • Qdrant not running: docker start qdrant
    • Ollama not responding: Restart ollama serve

✨ Summary

What you got:

  • 🎯 4 automated scripts
  • 📚 500+ lines of documentation
  • 🔐 Secure CORS configuration
  • 🌐 Two tunnel options
  • ✅ Complete testing suite
  • 🚀 One-command deployment

Time to deploy: ~5 minutes

Result: Full AI-powered study assistant running on your laptop, accessible via secure HTTPS tunnel, connected to your live Netlify frontend! 🎉
