How do you manage state globally in React?

To do this, use the React Hook useReducer to create a connected state to your reducer . useReducer takes in an initialState object and the reducer imported from the GlobalState component. Next, pass in the connected state and a dispatch function to modify that state.

Just wrap your app within a context provider and feed that provider with the data you want to make global:

To put it simply, global state is the data that is shared between all the components within a React application . When the state is changed, or let’s say a filter is added, the components re-render accordingly.25 Oca 2021

In the causal domain, a global state is a set of local states which are all concurrent with each other . By concurrent, we mean that no two states have a cause and effect relationship with each other.
