6. Next Steps
Involve Redux into React
Step 5: Connect Redux and React
To establish a connection between React components and the Redux store, we can use the
useSelector hook to access the state and the
useDispatch hook for dispatching actions.
Now, let's connect the Counter component to the Redux store.
- Line 2: Import the necessary hooks
react-reduxlibrary. These hooks enable the connection between React and Redux.
- Line 3: Import the
decrementaction creators from the
../redux/actions/counterActionfile. These actions will be dispatched to update the counter state in the Redux store.
- Line 6: The
useSelectorhook is used to access the
counterstate from the Redux store. We provide a selector function as an argument, which returns the desired state value.
- Line 7: The
useDispatchhook is used to access Redux's
dispatchfunction. It refers to the
dispatchfunction, which is used to dispatch actions to the Redux store.
- Line 9-11: Define the event handler
handleIncrementthat is called when the "Increment" button is clicked. We dispatch the
incrementaction to the Redux store inside the handler using the
- Line 13-15: Define the event handler
handleDecrementthat is called when the "Decrement" button is clicked. We dispatch the
decrementaction inside the handler to the Redux store using the
- Line 17-23: Render the JSX elements, including the current counter value and buttons for incrementing and decrementing. We attach the respective event handlers to the buttons'
This code connects a React component (
Counter) to Redux. It uses
useSelectorto access the counter state and
useDispatchto dispatch actions for state updates. The component displays the counter value and provides buttons to increment and decrement it. Clicking these buttons triggers actions that update the Redux store.
