Approach to Manage Global State with useContext hook
To create a context in any React app, you need to follow 4 simple steps –
- Create a context: A context in React is a way to share data between components without having to pass it through props. It acts as a global state container.
- Create a provider: The provider is responsible for making the context data available to all the components that need it. You wrap your app (or a specific part of your app) with the provider component. This is typically done in your top-level component (like App.js).
- Add provider to the app: You wrap your app components with the context provider. Any component within this provider’s scope can access the shared data using the useContext hook.
- UseContext: The useContext hook allows components to use the context data. Import the context you created and use it within a component.
In simple words when we are creating a context, we are creating a state. And when we create a provider, as its name says, we are creating a wrapper component to provide that state to all the components.
Implementing Global State Management with useContext
The useContext hook is a powerful addition introduced in React 16.8. It allows you to share context (or some value) with all the child elements within a context provider. This is particularly useful when you want to access data or state in child components without manually passing props down to each nested component. In this article, you’ll learn about useContext in depth.
