Original: 5 Angular Micro Frontend Mistakes That Only Show Up in Production

Short summary

An experienced Angular developer shares five production-only micro frontend architecture mistakes: over-sharing singletons causing version conflicts, fragmented auth handling, routing conflicts between remotes, missing fallbacks for failed remote loads, and uncoordinated deployments. Each mistake includes a concrete fix with code examples from a real government platform using Native Federation and Nx.

  • •Over-sharing singletons causes runtime version conflicts — pin versions and treat sharing as a contract
  • •Authentication must be a shell concern with one shared token service, not per-remote implementations
  • •Define routing contracts early: shell owns top-level prefixes, remotes own their namespace
  • •Every loadRemoteModule call needs error handling with fallback UI and monitoring
