The reducer will take the action and return new state. Other React Components will work with the Store via dispatching an action or getting value using React-Redux Hooks API. We’re gonna create Redux store for storing tutorials data. This diagram shows how Redux elements work in our React Hooks Application: – TutorialDataService uses axios to make HTTP requests and receive responses. AddTutorial has form for submission new Tutorial. Tutorial has form for editing Tutorial’s details based on :id.TutorialsList gets and displays Tutorials.– Three pages that dispatch actions to Redux Thunk Middleware which uses TutorialDataService to call Rest API: It has navbar that links to routes paths. – The App component is a container with React Router. Now look at the React components that we’re gonna implement: – Django & MongoDB React Hooks Redux CRUD Component Diagram with Router & Axios You can find step by step to build a Server like this in one of these posts: This is the point where custom hooks really shine - it’s based on other hooks - let it be other custom hooks or primitive hooks.Find all Tutorials which title contains keyword Since we do want our code to be DRY and maintainable for the long run, we can abstract away the redux boilercode with custom hooks. When the application grows, there may be other components that might be using the same selectors/action creators. However, we can this code even pretier and more useful. these functions may be passed as props to internal/nested components.if these functions are used more the once - we keep it DRY.The action creators - setSelectedBook(), addBooks() - are cached with the useCallback() hook so it wont be recreated again (optional) and for wrapping the calls to these functions with redux dispatch. Import = useSelector (selectBooksEntities ) const selectBook = useCallback (id => dispatch ( setSelectedBook (id ) ), ) const _addBooks = useCallback (books => dispatch ( addBooks (books ) ), ) return SomeJsx In this code example, there’s a Book container component that is connected to the redux store: Using React Redux Built In Hooksīefore React Redux added the hooks api, usually a component would have to be connected to Redux and “define” props and actions using the connect() along with its full setup. With Custom Hooks, we can make the store implementation agnostic, and expose a simple api for reading and update the state. Redux Or Hooks? Both!Įver since hooks was released, there were few good articles explaining on how Hooks differ from Redux, how Hooks may replace Redux and how Hooks work with Redux.įinally, I have found Hooks to be a complementry feature for working with Redux - the latest version of redux added hooks for selecting slices from reducers (selectors), adding dispatch to a component and few others. In a previous article, where I introduced Custom Hooks As A Service (CHAAS), I promised about sharing a custom hook strategy i’m working with - one that’s also good for integrating Redux and Hooks.
