The getDerivedStateFromError() method is used to render a fallback UI after an error is thrown, while the componentDidCatch() method is used to log error information. Just give this thread a comment and I’ll be more than happy to reply. We need to change all the this.props.bgColor to this.props.bgState.bgColor . And all the this.props.activeColor to this.props.activeState.activeColor .
Furthermore, Redux Middleware can be useful for dealing with asynchronous actions like API queries. Hooks are functions that let you “hook into” React state and lifecycle features from function components. Hooks don’t work inside classes — they let you use React without classes. When there is no need for large combined reducers, Redux may be redundant and “overkill”. With react hooks, we can manage global states without introducing additional dependencies.

We haven’t yet told our react app that we have a global state, or if you will, that we use redux state management. And right now, inside our App component, we can access the store state, the startAction and stopAction through props. So, the is redux necessary reducer will receive both of our actions, both of which are of type rotate, and they both change the same state in the app — which is state.rotating. Based on the payload of these actions, state.rotating will change into true or false.
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. What’s really different with Redux, is that we can have multiple context in our app so multiple store. https://deveducation.com/ First we are not using class components anymore, as explained in this article, Hooks cannot be used inside Class components and MUST be inside functional components. The state management of a React application is one of the biggest challenges you have to face when building an app.
Why use Redux?
Redux’s time-travel debugging feature allows you to replay actions and see how the state changes over time. This can be extremely useful for debugging complex state-related issues and understanding how the application state evolves over time. If this is a critical requirement for your application, Redux can be a valuable tool. If we want to compare those 2 functional components and the two components we had with Redux, it’s quite simple. Redux is good choice if your application has complex state management or if you need to share state between multiple components.
