How do I dockerize a React app?

Npm run build, then Dockerfile with nginx:alpine, COPY build to /usr/share/nginx/html, EXPOSE 80. Build and run with port map.

Why use nginx for React Docker?

Tiny 23MB, handles 10k connections, production king—beats Node bloat for static serves.

Multi-stage: build in Node, copy artifacts to nginx. Drops under 20MB easy.
