Introduction to Redux
2. Fundamental Concepts
Store Dispatch Method
Redux store object has a dispatch
method which can be used for dispatching actions.
When we want something to happen, for example, the counter value to be incremented, we can dispatch the counter/increment
action using the dispatch
method:
import { configureStore } from '@reduxjs/toolkit'
const store = configureStore({ reducer: counterReducer });
// The action object can be directly created inside the method call
store.dispatch({ type: 'counter/increment', amount: 7 });
// Or it can be passed using a reference
let incrementAction = {
type: 'counter/increment',
amount: 7
};
store.dispatch(incrementAction);
The reducer function will handle this dispatched action we passed into the Redux store, counterReducer
. The reducer function returns a new state object and updates the store accordingly – we don't have to do anything related to that; it is handled by Redux and happens on the backend, we dispatch the action using the store's method.
