Global State vs Event Bus
Developers should use global state when building applications with complex data flows, such as single-page applications (SPAs) or large-scale web apps, where multiple components need access to shared data like user sessions, shopping carts, or real-time updates meets developers should learn and use an event bus when building applications that require decoupled communication, such as microservices, frontend frameworks, or complex systems with multiple interacting modules. Here's our take.

Global State
Nice PickDevelopers should use global state when building applications with complex data flows, such as single-page applications (SPAs) or large-scale web apps, where multiple components need access to shared data like user sessions, shopping carts, or real-time updates
Pros
- +It simplifies state management by avoiding prop drilling and making state changes predictable, which is crucial for debugging and maintaining scalable codebases
- +Related to: redux, context-api
Cons
- -Specific tradeoffs depend on your use case
Event Bus
Developers should learn and use an Event Bus when building applications that require decoupled communication, such as microservices, frontend frameworks, or complex systems with multiple interacting modules
Pros
- +It is particularly useful for scenarios like real-time updates, logging, error handling, or coordinating state changes across components, as it simplifies event management and reduces direct component dependencies
- +Related to: publish-subscribe-pattern, message-queue
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Global State if: You want it simplifies state management by avoiding prop drilling and making state changes predictable, which is crucial for debugging and maintaining scalable codebases and can live with specific tradeoffs depend on your use case.
Use Event Bus if: You prioritize it is particularly useful for scenarios like real-time updates, logging, error handling, or coordinating state changes across components, as it simplifies event management and reduces direct component dependencies over what Global State offers.
