Online Code Editor (React + Vite)

A small React project that provides a browser-based JavaScript code editor with a live preview (iframe).

Quick start (PowerShell - Windows)

Install dependencies (use npm or pnpm)

npm install

Start dev server

npm run dev

Open the printed URL (usually http://localhost:5173)

Notes

• The preview runs user code inside a sandboxed iframe via srcDoc (no node access). Use caution when running untrusted code.
• This scaffold uses a simple textarea editor. Replace with CodeMirror or Monaco for a richer editor.
