Coding Terminal (Minimal Web Stack)

A very small web coding terminal you can run locally and deploy quickly.

Tech used (least possible)

• Node.js + Express: serve one HTML page.
• WebSocket (ws): real-time terminal I/O.
• node-pty: spawn a real shell process (bash/powershell).
• xterm.js (CDN): browser terminal UI.

Run locally

npm install
npm start

Open http://localhost:3000.

Deploy on the web (easy path: Render)

1. Push this project to GitHub.
2. Go to render.com and create a New Web Service.
3. Connect your repository.
4. Set:
   • Build Command: npm install
   • Start Command: npm start
   • Environment: Node
5. Deploy.

Render will expose your app publicly over HTTPS, and the app automatically uses wss:// when needed.

• Do not use as-is for untrusted public users without sandboxing/auth/rate limits.
