Global State vs Local State
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 use local state for managing data that is only relevant to a single component, such as form inputs, ui toggles, or temporary calculations, to keep components modular and avoid unnecessary complexity. Here's our take.
Global State

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
Local State
Developers should use local state for managing data that is only relevant to a single component, such as form inputs, UI toggles, or temporary calculations, to keep components modular and avoid unnecessary complexity
Pros
- +It is essential in modern frontend development with frameworks like React, where it enables reactive updates and efficient rendering without affecting the broader application state
- +Related to: react-hooks, vue-js
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 Local State if: You prioritize it is essential in modern frontend development with frameworks like react, where it enables reactive updates and efficient rendering without affecting the broader application state over what Global State offers.
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
