How does AngularJS support large-scale distributed frontend state synchronization?

AngularJS uses shared services, event buses, and backend-driven updates to synchronize state across distributed UI components.

In distributed frontend systems, multiple components across modules or micro-frontends need consistent state. AngularJS achieves this using singleton services as shared state containers, $rootScope event broadcasting, and backend synchronization via APIs or WebSockets. However, this approach risks inconsistency without strict state ownership rules. Large-scale architectures often introduce state management layers to enforce unidirectional data flow.
