Start Preview Server

Start the Next.js development server for local preview.

Steps

  1. Check if dependencies are installed:

    [ -d "node_modules" ] || pnpm install
    
  2. Check if port 3000 is available:

    lsof -i :3000 | grep LISTEN
    
  3. Start development server:

    pnpm dev
    
  1. Report the URL: http://localhost:3000

If Port 3000 is Busy

Suggest alternative:

pnpm dev -- -p 3001

Or kill existing process (with user confirmation):

kill $(lsof -t -i:3000)
pnpm dev

Docker Alternative

If Docker is preferred:

docker compose up

Server will be available at http://localhost:3000
