Good ‘React’ architecture is encouraged by React Redux.Being the official UI bindings for React Application, it is always kept up-to-date with any API changes.check to see if the data needed by the component have changed.The workflow of React Redux can be simply understood as: The official React binding for Redux is React Redux which is used to read data from a Redux Store, and dispatch Actions to the Store to update data. Redux is used by ReactJS for building the user interface and to manage the application state. Redux was inspired by Flux but it omitted the unnecessary complexity: it does not have Dispatcher concept, has a single Store and the Action objects is received and handled directly by Store in the Redux. So there are some risks you will be taking on if you choose to use it for a large project.Redux is an open-source JavaScript library which was first introduced in 2015 by Dan Abramov and Andrew Clark in 2015. However, it is still worth keeping in mind that it is an experimental library. Recoil does have some nice-looking benefits - it is possibly more performant, and has slightly less boilerplate to get started. Recoil is still in an experimental phase, while Redux is an established libraryĪnother thing to point out is that Redux provides middleware functionality, while Recoil does not yet support it.Recoil may provide performance benefits, but only if your app is complex enough.Even with Redux Toolkit, Redux is still more "boilerplatey" than Recoil.To summarise some of the differences between Redux and Recoil: Redux definitely does have some additional boilerplate to get started! Conclusion Redux also requires the useDispatch and useSelector hooks to be able to dispatch actions and use selectors.You'll need to define a selector separately Redux lets you create a store using createSlice() together with configureStore().This also comes with a selector and dispatchable action built-in Recoil lets you initialise a store using atom().Both libraries need you to wrap the entire app in a provider component.Redux vs Recoil: API differencesĬomparing the differences in API between Redux and Recoil: I also have to-do list examples of both Redux Toolkit and Recoil and other libraries over at react-state-comparison. Redux state management example Recoil state management example If you're interested in learning more, I have a separate post on Getting started with Redux Toolkit. ![]() Redux Toolkit is a helper library aimed to help you simplify how you use Redux. I'll be comparing Redux Toolkit with Recoil, to create a simple example that lets you change the value stored in a text box. ![]() So performance might not be the reason you need to switch to Recoil, but we can also compare the API of both libraries. ![]() I have a separate post on React Context that explains this issue, and provides a workaround library you can use called React Tracked. Any changes to state will cause re-renders for components that are using that state. Using React Context does have some potential downsides when it comes to performance. You might also be wondering - what about React Context? Do you need a state management library at all? I don’t think it’s worth switching to Recoil for the potential (maybe nonexistent) performance benefits. A regular app is probably going to perform just fine with Redux. With these performance optimisations, Recoil makes sense for huge apps that need to render a lot of components. However it will still need to check whether it needs to re-calculate. We can use optimisations like createSelector to reduce expensive calculations. The caveat here is that each time any part of the state changes, our taskSelector would have to re-calculate. With Redux, the component will only need to re-render when the specific task re-renders - same as Recoil. tasks // component code const task = useSelector ( taskSelector (id ) ) ![]() selector const taskSelector = ( id ) => state.
