Next.js Web Preview

Next.js Web Preview

This module demonstrates launching a full Next.js development server inside the TryNix Linux environment and viewing the live output in the Web Preview tab.

How it works

sequenceDiagram
    participant IDE as Code-OSS IDE
    participant VM as TryNix VM
    participant Preview as Web Preview tab
    IDE->>VM: npm run dev (port 3000)
    VM-->>Preview: HTTP responses
    Preview-->>IDE: Live page render

When you run npm run dev in the terminal:

  1. Next.js starts on port 3000 inside the Linux VM.
  2. The platform exposes that port and opens the Web Preview tab.
  3. Every file save triggers Next.js hot-reload — visible instantly in the preview.

Tip: The workspace terminal is fully interactive. You can run any shell command, install packages with npm install, and restart the dev server at will.
