Import ) ReactDOM.render(, document.getElementById('root') ) įinally, this is how the app looks in the browser after the implementation. Now we need to export the actions and the reducer. The locationSlice created above contains all the values required to create a reducer.

This will help to demonstrate on how to implement createSlice, dispatch action and configure store. Let’s create a small application to add a location name to the existing list dynamically. Redux state, on the other hand, is stored globally in the store. To share this state with other components in the application, props are passed to child components, or callbacks are used for parent components. Internally, it uses createAction and createReducer. Store: React state is stored locally within a component. This function aims to reduce the boilerplate required to add data to redux in the canonical way. In Redux-Toolkit, the createSlice method helps us create a slice of the redux-store. It automatically generates action creators and action types that correspond to the reducers and state.

What is createSlice in Redux Toolkit?ĬreateSlice is a higher order function that accepts an initial state, an object full of reducer functions and a slice name. At the end of the day all you have is less code and faster setups of Redux in every scenario. Redux toolkit includes all the tools, you want for a Redux application. Using this you can make your code more readable. By using this, you can write all the code you need for your Redux store in a single file, including actions and reducers. It is said to be an opinionated, batteries-included toolset for efficient Redux development. Redux Toolkit was introduced with a purpose to be the standard way to write redux logic. As you can see, the main players really resemble the players in Flux, except for the reducers and the lack of dispatcher object. The following figure show the Redux data flow: Figure 2: Redux Data Flow. It is most commonly used with libraries such as React or Angular for building user interfaces. All in all, Redux is a new pattern that took some aspects of Flux and implemented them differently. Redux is an open-source JavaScript library for managing application state.
