May 10, 2023 — The Redux Toolkit documentation calls the library a better way to write Redux logic for React apps and a simple and efficient toolkit for Redux development. In this article, you will learn about the Redux toolkit by building an app that tracks project issues. Read more…

February 11, 2021 — Headless CMS is a powerful and easy way to manage content and access API. Built on React, Sanity.io is a seamless tool for flexible content management. It can be used to build simple to complex applications from the ground up. In this article, Ifeanyi Dike explains how to build a simple listing app with Sanity.io and React. The global states will be managed with Redux and the application will be styled with styled-components. Read more…

December 14, 2020 — If you have used Redux at any point while developing an application to manage state, you will most definitely have come across reducers. In this tutorial, Fortune Ikechi will show you the concept of reducers and how they work, specifically in React applications. In order to understand and better use Redux, a solid understanding of reducers is essential. Reducers provide a way to update an application’s state using an action. It is an integral part of the Redux library. Read more…

November 27, 2020 — Reactive variables work with GraphQL Apollo and offer you the same functionality with Redux or Context API without the complexity or extra layers that come with these other tools. A reactive variable in GraphQL Apollo is easy to use and doesn’t have as much setup process compared to Redux. In this article, Daniel Don will look at how to set up reactive variables, how the GraphQL cache polices come into place in defining read and writes to the cache, and provide the ability for developers to add types that exist on the client-side alone so that we can structure queries for client-side variables same way we can for remote GraphQL data.

August 3, 2020 — Redux is a robust state-management library for single-page JavaScript apps. It is described on the official documentation as a predictable state container for Javascript applications and it’s fairly simple to learn the concepts and implement Redux in a simple app. Going from a simple counter app to a real-world app, however, can be quite the jump. Read more…

June 16, 2020 — In this article, we’re going to learn how to use Immer to write reducers. When working with React, we maintain a lot of state. To make updates to our state, we need to write a lot of reducers. Manually writing reducers results in bloated code where we have to touch almost every part of our state. This is tedious and error-prone. In this article, Chidi Orjil going to see how Immer brings more simplicity to the process of writing state reducers. Read more…

June 8, 2020 — In this tutorial, Shedrack Akintayo is going to learn about higher-order components, the syntax of higher-order components, as well as use cases for them. In the process, you will build a higher-order component from an existing React component. By the end of this tutorial, you will understand the basics of higher-order components and how to build them. Read more…

July 5, 2018 — Do you know Redux’s real power is beyond managing the state? Do you want to design with an understanding of how Redux works in mind? With the help of this article, Linton Ye would like to show you a full picture of Redux: what it can do, why it does its things, what the downsides are, when to use it, and how it relates to design. Even if you haven’t written a single line of code before, it’s still possible and beneficial to understand Redux. Expect plain English and doodles — no code or abstract talks. Read more…

May 19, 2017 — For every application Yury Dymov works on, he needs to decide how to manage the data. The problem can be broken down into the following three subproblems: Fetch data from the back end, store it somewhere locally in the front-end application, retrieve the data from the local store and format it as required by the particular view or screen. In this article, Yury sums up his experience with consuming data from JSON, the JSON API and GraphQL back ends, and it gives practical recommendations on how to manage front-end application data. Read more…

June 28, 2016 — Redux is a predictable state container for JavaScript apps. It’s an application data-flow architecture, rather than a traditional library or a framework like Underscore.js and AngularJS. It is used mostly for application state management. To summarize it, Redux maintains the state of an entire application in a single immutable state tree (object), which can’t be changed directly. When something changes, a new object is created (using actions and reducers). Today, Alex Bachuk will go over the core concepts in detail. Read more…
