State Management In React

In this discourse, our focus will be on local state management and the various React patterns we can use to avoid its common pitfalls.

Like Redux, Recoil is state management library in React. Let’s look at the differences and how to make the switch when you’re ready.

In this post I'm going to walk through how to implement global state management in a React application using the same pattern across 5 of the most popular libraries and APIs using the most modern and up-to-date versions of the libraries.

In this article, let’s discuss how React Query addresses the above-mentioned issue by building a small pokemon application and diving into its key concepts.

When I started at PayPal, the app I started with used Redux for its state management (like pretty much every other React app at the time). This was the first React product I'd ever worked on and I was excited to use the latest and greatest tools for state management.

In this post, I'll first introduce you to the localStorage API before we have a look at how to use it in React function components with React hooks.

Learn about the new library introduced by Facebook called Recoil, which aims to solve a few problems such as shared state, derived data and queries, app-wide observation, and many more.

Our goal is to explore some of Recoil’s main features in practice.

This weekend I decided to play with the new kid on the block - Facebook's Recoil library for managing state.

Recoil seems to be the new kid on the state management block — a block that’s considered overcrowded by many. Redux, MobX, Context… the list goes on and on.

Storeon is a tiny, event-driven React state management library built on the Context API, but with principles similar to Redux — and the same great DevTools.

No matter what it is you're building with React, when you boil it down, there are only three ways you can manage data 1 in a React app: locally, parentally, and remotely.

This tutorial walks you through the most common scenarios for managing arrays in React state. For each I want to show you a array example in React state, such as how to push an item to an array or how to update an item in an array, when React state is used to store it.

Multiple state management libraries have been published to further facilitate state management with the Context API, and in this article, I’ll be looking into Unstated Next.

If you have started working on ReactJS recently then you might be wondering how to manage state in React so that your application can scale.

In this article, we’ll look at how to use Kea in a React app as a global state management solution.

Do you have experience using React? Have you heard of Redux, but you've put off learning it because it looks very complicated and all the guides seem overwhelming? If that's the case, this is the article for you! Contain your fear of containing state and come along with me on this relatively painless journey.

Why using a status enum (or even better: a state machine) will help your app stay bug free.

Since Gatsby handles our routes for us, that leaves us with nowhere to wrap our app with a Redux store or provider. In this article we’ll learn a clever trick to get around that.

I have been developing React Tracked, which is a library for global state with React Hooks and Context.

Redux has been the go-to way to manage state within your React application for years. It's popularity is due in large part because when it was introduced, it solved a number of problems which were difficult to do in vanilla React on its own.

I have been developing React Tracked, which is a library for global state with React Hooks and Context.

For quite some time, Redux has been React developers go-to library for managing their app’s global state. It’s a great tool – but do you really need it?

State management is the core of any React application and as React is just a UI library, we need something to take care of the state of our app. State management can become troublesome and it is easy to create unmanageable React applications because of inconsistent state.

In this article, I will introduce the React Context API for state management and show you what makes React Hooks plus the Context API a better solution than Redux.

I was recently working on a Next.js project and wanted a few pieces of global state. I didn’t really want to go through all the setup for redux (nothing against redux, I love redux) so I decided to implement my own simple version of it using hooks.

In this article, we’ll cover the basics of RxJS and how to integrate it with React applications using React Hooks for state management. We’ll do this by building a demo chat application.

I've been moonlighting Gatsby projects in my free time for a couple of years now, while working with Next.js during the day. I've come to love MobX state management with Next, and wanted to bring the goodness to my Gatsby projects. Turns out that it's pretty easy, and I'm going to share the approach I took in a recent project.

In this extensive walkthrough, I want to guide you through all the possibilities of state management in React.

How to avoid state synchronization bugs and complexity with derived state.

What are Finite State Machines and how can you use them in React to make complicated logic and UIs easier to grasp? In this article we’ll set out to provide an answer to this question by building a video player in React.

By the end of this article, you should be able to manage your application’s state in a predictable manner without any third-party package.

In learning React, one of the first challenges I faced was figuring out state management. State is a vital part of any application that has more complexity than a simple blog or brochure site.

Why duplication in state management is a recipe for disaster

After making an update to your component’s state using either useState or this.setState, parts of the component re-renders depending on the update.

For this article, we will be working with a pattern for managing state using two very important Hooks, useContext and useReducer, to build a simple music gallery app. The application will have only two views: one for login and the other to list the songs in that gallery.

One of the biggest pain points when developing an app is the tricky business of managing state. Many bugs are caused by things getting into unexpected states, or by race conditions. Finite state machines can help eliminate both types of bugs entirely, while providing a welcome, structured way to build components.

In this tutorial, we’ll learn about what state actually is, and about the setState() method, the Context API and React Hooks. This is the foundation of setting state in React Native.

Since useAuth is taking off, I wanted to talk about the global state management technique that makes it work. You might find it useful too, or think it’s obvious, I was pretty excited when it clicked.

Since states are not meant to be updated directly (because React’s state has to be immutable), things can get really complicated as states become more complex. They become difficult to understand and follow. This is where Immer comes in and that’s what we’re going to look at in this post.

Today we're talking about avoiding bugs by structuring your data such that the bug can never occur.

We’re going to specifically look at how to manage state in both single and multiple components using Unstated Next.

How to manage state in your app can often be the biggest and most impactful architectural decision you make.

Global state or shared state is one of the biggest issues when you start developing a React app. Should we use Redux? Do hooks provide a Redux-like solution? I would like to show four patterns toward using Redux. This is my personal opinion and mainly for new apps.

There are several React Hooks that make state management in React Components possible.

A guide to local and global state management via useState.

This article will take you through the process of creating a reusable custom hook that persists our state to local storage.

How React is all you need to manage your application state.

There are two main hooks that are used for modern state management in React: useState and useReducer. This tutorial doesn’t explain both React hooks in detail, but explains their different use case scenarios.

In this tutorial, we will almost reach the point where these hooks mimic sophisticated state management libraries like Redux for globally managed state. Let’s dive into the application which we will implement together step by step.

A pattern for you to use in custom hooks to enhance the power and flexibility of your hooks.

In this Redux tutorial I’m going to explain how to use Redux with React incrementally – starting with plain React – and a very simple React + Redux example. I’ll explain why each feature is useful (and when you can skip some).

The words “simple” and “Redux” rarely appear together in the same sentence. And yet, much of the React community has come to embrace Redux as one of the best solutions for implementing application state.

Out of the box, React’s state management is limited to a component’s scope or at the very most, a shared state that requires wiring components together. This lack of a global state is why things like Redux and various other packages exist. New on the scene is ReactN which is an extension of React that comes with state management at a global scale baked right in.

So far, it was fine to rely only on React’s local state and React’s Context API. This tutorial dives into using MobX on top of React and Firebase for the state management.

This tutorial dives into using Redux on top of React and Firebase for state management. You will exchange React’s local state (e.g. users on admin page, messages on home page) and React’s context (e.g. session management for authenticated user) with Redux.

How to use React Context API in an easier and prettier way.

A question people ask me regularly: “How do all the new React features (context, hooks, suspense) affect how we build (web) apps in the future? Do they make state management libraries like Redux or MobX obsolete?” With this post, I’ll try to answer that question once and for all!

Immer is a tiny package that allows you to work with immutable data structures with unprecedented ease. It doesn't require learning new data structures or update APIs, but instead creates a temporarily shadow tree which can be modified using the standard JavaScript APIs. The shadow tree will be used to generate your next immutable state tree. This shadow tree is maintained using Proxies.

Many battles have been fought over what is the best way to do state management. A gazillion of strategies and libraries are out there. So,.. it is time to take one step back. Why is state management relevant in the first place? What problems does it solve? For example, many debates are about mutability or immutability. But then Michel proposed that the more fundamental question to ask is: identities or values? With these concepts in mind, Michel took a look at several libraries and frameworks and recognize the patterns.

Tweaking our main component so that it saves stuff to localstorage was cool and all, but we can do better: A middleware approach that ties into our state library.

Need to preserve some user state across sessions? Here's a quick and dirty way that works really well. Dump the important parts of your data store to localstorage on every change.

Many teams have been discussing on whether to go the immutable or mutable state route. Flux or MVC or MVVM? Redux, MobX or Apollo? Instead of answering the question, in this talk we will look at JavaScript code on a more fundamental level: How do data structures work in JavaScript. What assumptions can be we make if we treat them to be immutable? Or mutable? How can we express concepts like identities, references, collections, mutations, derivations in either case? And can we bent the rules between the two? This talk will provide you a deeper understanding of the difference between state and data.

Redux is the most widely-used state management library for React applications, and has spread throughout the Javascript ecosystem. However, the learning curve can be steep for many people. Come join Redux co-maintainer Mark Erikson as we talk about the core concepts of Redux, how to use Redux with React, and how Redux was designed to make Javascript applications predictable.

We take an app from component state to MobX, then the same app from component state to Redux and talk about the differences. Async code in both MobX and Redux is covered!

In this video we will talk about what Redux is and build a React app from scratch and add all of the boilerplate for Redux and work with the store/state, actions, reducers and all of the other fundamentals of the Redux state manager.

Here we look at how MobX State Tree works and how it compares to MobX.

React and its component model is nowadays the most appealing abstraction to declaratively describe user interfaces. The core concepts are so powerful that we can apply them outside the DOM, like in React-VR, Sound manipulation, games etc. In this talk I will demonstrate that all the core ideas powering React are so powerful that we can even translate them to a completely different field: state management. MobX-state-tree applies these very same concepts to make data management declarative, elegant and easy to reason about.

Last years there have been great developments in state management libraries. Both Redux and MobX sprung from the React community and provide stand-alone, generic state management solutions. Both have gained big in popularity, and both have their own strengths and weaknesses. What can we learn from both approaches?

"Reactive programming" still sounds scary to many developers. As if it is an elevated way of thinking, only accessible to the chosen few. Nothing is less true! It is the most natural way to look at programming problems. You just might not realize it yet! In this talk, Michel will demonstrate that many complex UI problems, such as form validation and routing, can all be seen as '*actions* that change *facts* which leads to *reactions*'. And as soon as we start distinguishing those concepts in our applications; our code will become more declarative, more concise and less imperative.

At React Amsterdam, you can meet its full-stack lead developer Michel who strongly believes in pragmatic, agile and the-simplest-thing-that-could-possibly-work programming.

At Mendix we use MobX to manage the state of our visual enterprise application studio. In this talk we will take a look behind the scenes and see how MobX simplifies concerns like authentication, data fetching and routing. The strong decoupling of state and UI helps us to iterate on our UI more quickly. The architecture of the studio is pluggable and we will see how MobX helps integrating external producers and consumers of state into the product. In the end, we believe that this approach results in a code base that is sane and accessible. In which we get things done quickly.

State is the heart of each application and there is no quicker way to create buggy, unmanageable applications then by producing inconsistent state. Hence many state management solutions try to restrict the ways in which you can modify state, for example by making state immutable. But this introduces new problems; data needs to be normalised, referential integrity can no longer be guaranteed and it becomes next to impossible to use powerful concepts like prototypes.
