How do you design AngularJS applications to survive partial system outages in microservice ecosystems?

AngularJS apps survive microservice outages using fallback UI states, cached responses, and isolated API failure handling.

In microservice ecosystems, backend services can fail independently. AngularJS must isolate these failures so UI remains functional. This is achieved by wrapping every API call in service-level abstraction layers with fallback logic. Cached responses are used when services fail, and UI components degrade gracefully instead of crashing. Interceptors normalize error responses so UI logic remains consistent.
