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

Nice Pick

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

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.

🧊
The Bottom Line
Global State wins

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
