Micro Frontends, Five Years After
summary
DAZN started a micro‑frontend rollout in 2019 and scales it to millions of users by mixing vertical microfrontends (full‑page, single‑team) with a few systemjs‑based horizontal modules for the player, composing everything with a tiny client‑side orchestrator (three lines to mount pages). Communication relies on localStorage/window until host‑config props appear, teams duplicate simple UI (five or six headers) to avoid coupling, analytics and payments become shared services, and the hybrid approach proves workable but requires deliberate discoverability and governance.
