🚀 Quick Start (Local Development)

📋 Prerequisites Check

Ensure you have the required tools installed. Open your terminal or command prompt and run:

• Node.js (v18+): node -v
• npm (v9+): npm -v
• Git: git --version
• A Supabase account (free tier is sufficient)

1. Clone the repository

git clone https://github.com/mayo-byte07/Conn.git
cd Conn

2. Install dependencies

The installation process is similar across operating systems:

Linux / macOS / Windows:

npm install

(Windows Users: Conn uses bcryptjs, a pure JavaScript implementation, so you do not need Python or Visual Studio Build Tools to compile native modules!)

3. Set up Database (Supabase)

1. Create a free project at supabase.com
2. Go to Dashboard → SQL Editor
3. Paste and run the contents of scripts/setup-db.sql
4. Go to Settings → API and copy your Project URL and service_role key

4. Configure environment variables

Create a .env file in the root directory:

Linux / macOS:

cp .env.example .env 
nano .env

Windows:

New-Item -ItemType File -Name ".env"
notepad .env

⚠️ IMPORTANT: JWT_SECRET is required. The server will exit immediately if it's missing.

Add the following to your .env file:

SUPABASE_URL=https://your-project-id.supabase.co
SUPABASE_SERVICE_KEY=your-service-role-key
JWT_SECRET=your-random-secret-min-32-chars

💡 Tip: Generate a secure JWT secret by running: node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"

5. Start the server

npm start

Visit http://localhost:3000 to see your local instance running! 🎉

6. (Optional) Seed existing data

If you have local JSON data files from a previous version, you can migrate them:

npm run seed

☁️ Deploy to Vercel

1. Push to GitHub

git add -A
git commit -m "Initial deploy"
git push origin main

2. Import to Vercel

1. Go to vercel.com/new
2. Import your GitHub repository
3. Go to Settings → Environment Variables and add:

Variable	Value
SUPABASE_URL	Your Supabase project URL
SUPABASE_SERVICE_KEY	Your service_role secret key
JWT_SECRET	Your JWT secret string

🛠 Troubleshooting

Port already in use

If port 3000 is already occupied, stop the existing process or use a different port.

Supabase connection issues

Verify that:

• SUPABASE_URL is correct
• SUPABASE_SERVICE_KEY is valid
• Database tables were created successfully

JWT errors

• Ensure JWT_SECRET is properly added in the .env file
• The server will exit at startup with a clear error if JWT_SECRET is missing
• Generate a secure secret: node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"
