If you are using Redux and React together, you should also use React Redux to bind these two libraries. Personally, I would like to create another folder named utils and create a context in it, but it doesn’t matter much and depends on your preference. The authentication state can influence our app in many places and determine what information to show, so this can be a useful case as an example. The goal of this article is not to explain how Redux works, but how to replace Redux by Hooks.

One thing you need to understand is that hooks aren’t meant to replace redux stores nor are they used for global store management. You use redux so that multiple components in your app can use the same redux store. For example, say you have 2 components a that says “Hello user_name” and a that says “Welcome user_name”. Now both these components require the same data which is user_name. If we use a redux store we can store the data in a single location and use it throughout the app by passing it as a prop.

What is React Router?

RTK Query replaces the need to write any actions, thunks, reducers, selectors, or effects to manage data fetching. You should always start by replacing the legacy createStore call with configureStore. This is a one-time step, and all of the existing reducers and middleware will continue to work as-is. PocketBase is a performant Go-based tool that comes with essential features like user auth, file uploads, access control rules, and more. When the button is clicked, it triggers the dispatch function with the specified action type, which will be handled by the reducer function to update the state accordingly. React Hooks provide an alternative to writing class-based components by allowing us to easily handle state management from functional components.

If the mutation function throws an error, Redux Query executes onError. All we need to do is set the query to the context parameter if the backend call fails. The mutation function in this case calls the backend with updateName to change the name stored in the database. As the official Redux binding for React, React Redux is kept up-to-date with any API changes from either library, to ensure that your React components behave as expected. Its intended usage adopts the design principles of React – writing declarative components. Since we export with wrapped around, now the component is an app component with all the states and handlers we need for user authentication.

Modernizing Redux Logic with Redux Toolkit​

Use the Context API when you have data that many components need to access and it would be cumbersome to pass data down as props through each level of the component tree. React Hooks are functions that allow you to “hook into” React components using state and lifecycle features in functional components. They provide a way to use state and other React features without writing class components. Once you declare your state using either useState or useReducer, you’ll need to lift it up to become global state using React Context. This is done by creating a Context Object using the createContext function provided by the React library.

For this example, we’ll build a simple counter demo consisting of a two-button component and a display component. We’ll introduce a count state that will be shared globally among the two components. The components will be a child of CounterView, which will act as the container. The button component will have buttons that will either increment or decrement the value of the count state. Expo Router provides an excellent file-based routing solution with crucial features such as deep linking and native support.

React Hooks vs. Redux: Do Hooks and Context replace Redux?

All you need to do is pass a function into Formik’s validate prop. This will update the formik object’s values object with the new value so that we can retrieve it from the values object in the onSubmit props. The new query and mutation can be used in the following way in the React component.

Redux is a predictable state container for JavaScript applications that helps us write applications that behave consistently, run in different environments, and are easy to test. Now, this exported history object will be used in the both places where it is needed. Technically, there’s a DOM history object for manipulating the browser’s history session. In the dev world, there are usually multiple ways to solve a problem.

FAQs about React Hooks and the React Context API

You may even go a little further and actually render some UI component based on the passed-in state. Within the state object you may now store any key value pairs you wish to carry over to the route being redirected to. Now, if appState is equal to DO_SOMETHING_OVER, the Redirect component is rendered. First, remember that on hitting the home route, theAngryDude component is rendered.

• 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 this setSubmitting function is called with Boolean true, then isSubmitting is set to true.
• Technically, there’s a DOM history object for manipulating the browser’s history session.
• Validation can be done in between user inputs, and an arbitrary submit function is executed on form submit.
• In this React Router and Redux tutorial, we’ll show you the nuances of navigating within your React/Redux applications and demonstrate how to do so declaratively.
• With React v16.3.0, the Context API was released, which allows developers to implement global state without installing additional libraries.

Building forms the natural React way requires you to write every part of the process from setting up states to form submission. I have done countless React forms and I always find this part of building forms very boring and time-consuming. React only provides the “view” layer for your application, and that means it provides only the basic necessities in making form components. Component, state, and props are like puzzle blocks that you have to piece together to build a working form.

Step 2: Define context

Instead of using dispatchers of the auth reducer, we can define our handlers to make it even easier to understand and pass them into the global context. We know that reducers update their current state based on the input actions. An input action is an object that defines the type of action as what is redux well as other needed data. The dispatch function of the useContext will work exactly as the one of Redux. It takes an object that must contain a type, corresponding to the action to dispatch. This action will be received in the reducer, that will save it in the store of the current context.

On the other hand, with React Hooks and the useContext API, there is no need to install external libraries or add a bunch of files and folders to make our app work. This makes it a much simpler, more straightforward approach to handling global state management in React applications. However, we need to wrap these Route components in a ConnectedRouter component from the connected-react-router library.

However, its verbosity makes it difficult to learn, and the extra code needed to get it working can introduce unnecessary complexity. Where the reducer refers to a reducer function in reducers/index.js, but that won’t be the case very soon. The react-router-redux maintainers advise using Connected React Router. Simply pass in a second object parameter into the history.push function.
