Now, for updating the pageCount we will use (Math.ceil(data.length / postsPerPage)) and further store it using setPageCount hook. Then, update the state with postData using React hook setAllPosts. Further, we will loop the data using a map function, return the HTML structure and store it in the variable named postData. The motive behind the JavaScript function – slice, is to slice our data, i.e., 100array.slice(0, 0+5)). Here we will fetch data using Axios and then store the response in the variable named data. SetPageCount(Math.ceil(data.length / postsPerPage)) I personally prefer redux toolkit over regular redux because it lessens the boiler plate code a lot.Const slice = data.slice(offset - 1, offset - 1 + postsPerPage) That’s it for the redux toolkit tutorial, you can find the full code here. Which is a function inside the Redux Toolkit package. To build the slice, you need to import createSlice. In it, You should define the initial state and the functions that will be needed to change the state when necessary.

The slice is the component that keeps track of the app’s state. Installing Redux ToolkitĪfter cloning the repository above and installing packages, you should install redux toolkit and react-redux using the following command: npm install react-redux Our goal in this part of the article is to make the user able to add and remove to-dos from the list. Now that we have our UI ready, you’ll see that I’ve hard-coded the to-do list items. I won’t be focusing on the UI in this tutorial, so I made this github repository that you can clone that has the UI already created for you.

If the sliced portion is sparse, the returned array is sparse as well. The slice () method preserves empty slots. They eliminated a bunch of boilerplate code and made redux state management easier to create. It does not alter this but instead returns a shallow copy that contains some of the same elements as the ones from the original array. The creators of the package intended to make it the default way to write Redux logic.

I personally prefer redux toolkit over regular redux because it is much easier to use. In this tutorial, I’ll explain how to use the Redux toolkit by building a small to do list app that keeps its state using Redux Toolkit. Redux Toolkit is a react package for state management built on redux. Both arguments of slice() stand for zero-based index numbers or negative offset values.
