AI-Generated Review

What is green-screen-react?

Green-screen-react is a TypeScript React component that emulates legacy terminals like TN5250 for IBM i, TN3270 for mainframes, VT220 for Unix, and HP 6530 for NonStop—all in the browser. It bridges WebSocket to TCP via a Node.js proxy or one-command Cloudflare Worker deploy, delivering real-time screen updates, field-aware input, and function keys without native apps. Drop it into any React 18+ app with zero runtime deps for instant green screen access.

Why is it gaining traction?

Mock mode lets you eval with fake screens—no host needed—while production deploys to free Cloudflare tiers with auto-env setup for Vite/Next.js. Typing animation, auto-reconnect, and CSS theming make it feel modern, plus pluggable adapters for custom backends. Multi-protocol support covers most enterprise greenscreens in one lightweight package.

Who should use this?

Frontend devs embedding mainframe access in SPAs for ERP dashboards or customer portals. SaaS builders needing web-based terminal proxies without server management. Teams migrating legacy COBOL/RPG apps to React while keeping live host connections.

Verdict

Solid docs and MIT license make it eval-ready despite 12 stars and 1.0% credibility—test with `npx green-screen-proxy --mock` today. Niche but mature for its scope; scale cautiously until more adoption.
