Vibe coded an open-source library that runs Node.js entirely in the browser.
What it does:
→ Full virtual filesystem with POSIX-compatible API (using just-bash from @cramforce)
→ 40+ shimmed Node.js modules (fs, path, http, crypto...)
→ Install real npm packages client-side
→ Run Next.js, Vite, and Express dev servers
→ HMR, TypeScript, CSS Modules
No server. No backend. No cold starts.
