Local State vs Global 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 meets 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. Here's our take.
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
Local State
Nice PickDevelopers 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
Global 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
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
The Verdict
Use Local State if: You want 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 and can live with specific tradeoffs depend on your use case.
Use Global State if: You prioritize it simplifies state management by avoiding prop drilling and making state changes predictable, which is crucial for debugging and maintaining scalable codebases over what Local State offers.
