React State Management: React Hooks vs Redux io

They allow us to hook into React’s core features and handle state management easily. In comparison, React Hooks (such as useContext and useReducer), combined with the Context API, offer a simpler and more lightweight approach to state management. They are particularly suitable for smaller applications or cases where the complexity of Redux might not be necessary. When choosing between React Context API and Redux, it’s important to consider the specific needs and constraints of your project. React Context API is more suitable for scenarios where state updates are infrequent or simple, and centralized state management is not critical.

No, because there is a lot of state in an application which is ephemeral and too granular to provide very useful information for things like logging telemetry or time travel debugging. Unless you’re building a realtime collaborative editor, you probably don’t need to put every user keystroke or mouse movement into Redux state. When you add things to Redux state, you add a layer of abstraction and the complexity that goes along with it. It helped that there are plug-and-play tools to manage form state with Redux, so I didn’t have to worry about ephemeral form state bleeding into my business logic.

If you’re reading this, you probably understand how the promise and async/await are different in the execution context.

Context API provides a scalable and simple framework, making it a great way to implement shared data between components. The new version of Context API is a dependency injection mechanism that allows passing data through the component tree without having to pass props down manually at every level. Redux is a library for managing and updating the application state using events called actions. It’s a centralized store that’s shared across the entire application and ensures that the state gets updated in a predictable fashion. Using components is a great way to structure web applications because they make it easier to reuse code.

During the Initial render, the value supplied as the initial argument is identical to the state (state) returned (initialState). Updates to the state are made via the setState why redux function. The component is re-rendered and accepted when a new state value is provided. React Context API enables us to share data between components without using props.

Once that’s done, we can add Redux and create the first version of the counter application. The context is received as an argument to a function which you pass as a direct child to . You can define the Context object in a separate file or right next to a component in a component file. You can also have multiple Context objects in one and the same app. For the last few years, Redux has been THE state management solution for bigger React apps.

You need to know which data needs refreshing and how often. If we work on a larger, complex endeavor, we choose Redux for global state management. At the time of writing this article, the interface of Context API isn’t optimized for high-frequency updates. You can face this issue when trying to move to React Context internally in your package.

So, if you are working on a React Native project that will eventually grow very large, Redux is a great way to go. The boilerplate code can be overwhelming at first, but it’ll help with code architecture and organization. Inside the src/App.tsx, let’s create an atom called counterState. We can now register the store within our React Native application. As stated earlier, in Redux, actions are objects that describe what has to be done.

It’s a container component that delegates DOM concerns to an imported presentation component. You may have a good use case for React’s built-in component state model. For example, the following form uses the local component state useState hook from React. React hooks let you use state and React lifecycle features without using class and React component lifecycle methods. Context API prompts a re-render on each update of the state and re-renders all components regardless. This can be monitored on the console as there's a log in each component.

• On top of that, it provides a great developer experience, such as live code editing combined with a time-traveling debugger.

This is the data that we want to pass around the components or store in the state. React supplies a useReducer hook that will interface with your Redux-style reducers. That’s great for non-trivial state logic, dependent state, and so on. You don’t always need Redux for every app, or every component. If your app consists of a single view, doesn’t save or load state, and has no asynchronous I/O, I can’t think of a good reason to add the complexity of Redux.
