How We Brought 20+ Airport Services into One Frontend Without Hitting Turbulence

On the AeroPort project, we built a microfrontend architecture for a large international airport: flights, baggage, security, retail — 20+ independent services run inside a single shell using Module Federation and Single-SPA.

What did that give us? Each service deploys independently and does not take down its neighbors. In other words, the baggage team ships a feature, and the flight boards stay up — exactly the kind of release process you want.

To keep the frontend from growing to the size of a Boeing, we optimized shared dependencies: tree shaking, lazy loading, and vendor chunks helped keep bundle size under control.

Against the background of the trend toward modular architecture and the constant race to ship faster, this is a genuinely workable setup, not hype for hype's sake.
