The Micro-Frontend Revolution at Amex
summary
American Express claims micro‑frontends scale a site for thousands of engineers by shipping independent React Holocron modules served from a CDN, composed and server‑rendered by a long‑running Node.js “one app” that watches a JSON module map. Each module has its own repo and CI/CD, local dev composes one changed module against production bundles via Docker, deployments happen at runtime with no server restarts, and the approach reports success in production since 2016.
