Flight is an open‑source, TypeScript‑first Node.js web‑server that lets teams build component‑driven full‑stack apps with fast, clustering‑ready performance and built‑in Redis‑backed sessions, rate‑limiting and caching. It provides “plug‑and‑play” backends discovered from `*.backend.ts` files, Vite‑powered Vue development (React on the roadmap), and production‑ready SPA static serving, making it ideal for engineers who need a portable, twelve‑factor‑compatible runtime for high‑traffic services.
