3/21/2023 0 Comments React redux hooks![]() ![]() ![]() Redux is offering this feature, but in plain React we would have to implement it ourselves. One: First, there is no native feature (yet) which combines all reducers to one ultimate reducer. There are two ingredients missing to make it one and global as in Redux. However, even though we are able to lift all the useReducer state up to our most top-level component - almost making Redux obsolete because it can be seen as global state container - it still isn't one global state container. Let this fact sink for a moment before we continue extending useReducer's component co-located state management philosophy. While Redux creates one global state container - which hangs somewhere above your whole application -, useReducer creates a independent component co-located state container within your component. ![]() Where your state is managed is a crucial difference between Redux and useReducer. Global State Container and Component Co-Located State Also if you want to learn more about Redux, check out this extensive Redux tutorial. It's good to know about the fundamentals before entering this discussion about Redux vs useReducer. Requirements: Check out the following tutorials, if you haven't learned about reducers in JavaScript or useReducer in React. Now, many people keep wondering: Does useContext and useReducer replace Redux? As of the time of writing this article, React Hooks don't replace Redux. There are two hooks that are used for modern state management in React (useState and useReducer) and one hook called useContext to use React's Context API to pass state or state updater functions down the component tree. With this library, you can use nested data structures with little to no performance loss thanks to mutations, scoped states, and other optimizations.Īdd to all that a good extension system, TypeScript and Redux DevTools support, and Hookstate looks to be one of the most attractive solutions for fans of React hooks.Since React Hooks have been released, function components can use state and side-effects. On top of that, Hookstate is very scalable thanks to its handling of nested state. get () ? "Available" : "Unavailable" ) // Accessing state outside component // Inside React component const state = useState () const isAvailable = state.isAvailable. set ( false ) const status = () => (state.isAvailable. set ( true ) // Changing state outside component const makeUnavailable = () => state.isAvailable. const isAvailableState = atom () // Wrapped "actions" const makeAvailable = () => state.isAvailable. You can think of it as an equivalent to React’s local state ( useState), but with the ability to be shared among components and created outside of them. An atom is a unit of state that wraps and represents a single state property. The core concepts to understand in Recoil are atoms and selectors. Although it’s still in an “experimental” phase, Recoil is already relatively stable and feature-rich. Partially thanks to its atomic, React-inspired approach to state management, but also thanks to it coming straight from the Facebook team. Since its announcement in early 2020, Recoil has gathered a fair bit of interest from the React community. This article will go through the top 6 of those libraries and compare them to see which one is the best choice for your next React app. Thus it’s no wonder that there are so many open-source libraries designed specifically to make state management easier and more enjoyable.įrom the multitude of JavaScript UI frameworks, React is likely the one that enjoys the most vibrant ecosystem, including state management libraries. The app’s state dictates what users see, how the app looks, what data is stored, and so on. State management is one of the most important aspects of every app.
