Building Universal Apps
summary
Claims that one JavaScript codebase runs unchanged across browser, mobile, server and embedded devices and demonstrates it with concrete tools: JavaScript in nginx, node.js, Express, React/Redux, TypeScript, Electron and Raspberry Pi. Shows a working door unlock system that routes mobile, server and hardware calls and explains dependency injection and error propagation. Reports performance tests reaching about 27,000 requests on an 8‑core machine (≈3,000 per instance), and recommends worker processes over threading for concurrency.
