preview（preview 命令行）

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
4. 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
