How do you design AngularJS systems to handle cascading failure scenarios in distributed frontend architecture?

Cascading failures are prevented using isolation layers, circuit breakers, and dependency decoupling strategies.

Cascading failures occur when one failing component triggers failures across dependent modules. In AngularJS, this happens when multiple services depend on a single unstable API or shared service. Prevention requires circuit breaker patterns in API services, isolation of feature modules, and limiting cross-module dependencies. UI should degrade independently per module instead of collapsing globally.
