Using Redux With React

A look at the motivations, design, and goals for Redux Starter Kit.

Redux is a whole mindset shift for many people in the JavaScript community, who literally grew up with only web development, but never heard about function composition or immutability before. Whether Redux stays with us for a few more years or makes place for other state management libraries, it leaves a great legacy on how we develop modern web applications.

Run Redux in Web Workers

React components connected to Redux can turn out pretty complex. Thus most people think that testing these complex components can turn out very complex as well. But it shouldn't be complex at all, if you take full control of the Redux store in your integration/unit test for the React component.

Having worked on a fair share of React and Redux applications, I can’t help but notice that many people have a hard time indicating to the user that a given action is currently taking place.

So it has been a hot reloading minute since React released their hooks API and I think it is fair to say that the majority of the community have played around with the new API. If you haven’t already, I definitely recommend it as they are great.

I have been developing several React hooks libraries for months. In this post, I will explain why and how I developed a React Redux binding library with React hooks. The library is implemented to be concurrent mode friendly. Let’s discuss why it’s important and what’s the technique behind it.

The following implementation shows you how to integrate Redux Persist into Next.js with a quick example.

This article assumes a working knowledge of Redux, React, React-Redux, TypeScript, and uses a little bit of Lodash for convenience.

Some observations on the tradeoffs involved in using React hooks.

Building stateful modern applications is complex. As state mutates, the app becomes unpredictable and hard to maintain. That’s where Redux comes in. Redux is a lightweight library that tackles state. Think of it as a state machine.

We always use the react-redux library in our React apps whenever we decide to include state management in our React app.

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.

With the recent release of create-react-app v3 and React hooks, I decided to write a tutorial on how to refactor a class component to a functional hooks component.

Now, many people keep wondering: Does useContext and useReducer replace Redux? As of the time of writing this article, React Hooks don’t replace Redux.

You might’ve run up against this concept in Redux called a “selector.” In this short tutorial I’ll explain what selectors are, why they’re useful, and when (and when not) to use them.

In this tutorial we will be going over how to integrate React Hooks into a React Redux project without changing the Redux code (reducers and actions) at all.

This article will take you through how you can implement an API similar to Redux yourself. Not because you'll want to do just that, but because it'll help you understand how Redux works!

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).

For those of us coming from a Redux background, useReducer can seem deceptively complex and unnecessary. Between useState and context, it’s easy to fall into the trap of thinking that a reducer adds unnecessary complexity for the majority of simpler use cases; however, it turns out useReducer can greatly simplify state management.

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.

After you've set up your React application you need to install a tool called redux-thunk by using the command npm install redux-thunk.

Gatsby + Redux is a powerful combination when building static web-apps with dynamic features. With Gatsby 2, it has never been easier to get up and running. Today, I’m going to guide you through the steps needed.

The React Redux connect function works great for regular React components, but if you need access to the Redux store in a plain function, the technique is a bit different. In the examples below I’ll show how to access a JWT token from the Redux store, but the techniques will work with any data you might have.

Learn to create a simple React/Redux integration using Hooks, then improve the performance using JavaScript Proxies.

Ever since React Hooks feature was announced and the API went public, I have been thinking about what this means for Redux — a well known state management library.

This blog post is for JavaScript developers who wanted to develop a Web Application using Full Stack capabilities of JavaScript.

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.

There is no one clear way how to handle asynchronous calls to the API (backend) or any other side effects. In this article I’m trying to compare different approaches to solving this problem.

In our last post we covered the bulk of how Redux works with createStore. In this post we'll cover the various other files in the library. While some of these contain simple utilities, others are much more complex.

I spend a lot of time walking people through Redux best practices and how to use it, and throughout this process I've found it really helpful to dive into the source itself. While this source is very readable and well commented, I thought I'd put together a blog post to break it down and add some more context.

This guide presents a very simplified example of a Redux implementation. I will define each of the steps and terms in a way that makes sense to a complete beginner.

The simplest React Redux tutorial I wish I had when I started learning

A complete React Redux tutorial for beginners: Learn how to build React Redux applications from scratch by following this step by step implementation of an example application.

In this article, I am going to add Redux on top of one of the projects that I have worked over the last one and some years.

Do you avoid testing of components that depend on Redux because you fear the complexity? Are you loosing sleep worrying about configuring huge mock stores for testing the simplest of components? Fear no moarrr!

The following is a visual guide to learning Redux. One focused on the core Redux principles explained with memorable associations and custom illustrations.

In this article, we propose another bindings library to combine React and Redux. This library tries to be simple and easy for beginners. As of writing, this is still an experimental project and feedbacks are welcome.

While I worked on a recent project at work, I had to implement filtering and sorting (for a table) through some URL query parameters.

Redux can help address some of the issues that arise as your web application grows in size.

It’s important to understand why and not just follow advice blindly.

These days, to achieve optimal app load times when users visit our website, we are questioning every byte of code that is being transferred on the network.

Before reading the rest of the tutorial and going further, just try to remember that you are only learning about Redux because it will make things easier for you, and not more difficult.

From Big Containers to Small Connected Components

I will try to explain what is Redux Thunk by building a Github Search application.

Sadly, state management is just one of the many issues you have to deal with while building robust applications. What about handling side effects (like network requests, the most common)?

In this article, we will learn how to persist user data using Redux in a React Native application.

This article is about how to think in Redux. We’ll try to understand how we can utilise this wonderful library to make our application more stable, robust, and maintainable.

In this part we’ll cover some simple examples on how to test Redux reducers.

Let’s dig deeper into what Redux can do, why it does its things, what the downsides are, and how it relates to design.

Along the road of getting React into our codebase, we stumbled upon the most challenging bits of doing frontend development: state management.

In this part we’ll cover some simple examples on how to test Redux actions.

When having a GraphQL server, Apollo Client can be a valid option for your remote data. How fits Redux into the equation? This tutorial shows you an example on how Redux and Apollo Client can be used together in a React application. Whereas Redux is used for local data, Apollo Client is used for remote data.

Have you noticed the boilerplate code when coding Redux? I bet you have! But you know what? Redux doesn’t enforce you to use all of it. There are shortcuts you can take. Shortcuts that are ok to use!

Redux makes sense but when React comes into play with the react-redux package you get confused.

I prefer to apply the KISS Principle when solving problems, so the same goes for testing React-Redux apps.

After the First Taste of Redux I worked through the Building React Applications with Idiomatic Redux course.

This article mainly focuses on implementing some good practices I follow when building large scale applications with React and Redux.

This article’s goal is to explain the core concepts of Redux by making a CRUD application.

“What?!”, you say. “GraphQL is a server side query language. Redux is a client-side state management library. How could one replace the other?” Good question.

Shouldn’t state management be a solved problem by now? Intuitively, developers seem to know a hidden truth: state management seems harder than it needs to be.

Have you read Redux tutorials, but it is still not making it into your brain? We are all looking for that moment where it just clicks and we understand it. I hope this article takes you one step closer to that moment.

A tutorial to understand the core Redux library by building it step-by-step.

The new context API that comes with React 16.3 is pretty neat. It was built in the render props style trending over these last months. Let’s explore it.

In this post, I’m going to discuss Redux, how it’s deeply rooted in the concepts of functional programming, and how to decide if you need it in your application.

You are now ready to take the next step, but what is the next step? Taking yet another tutorial? Write another TODO-app? Pay for a “mastering React” course?

An extensive guide of tips, tricks and resources to learn React.js and Redux in 2018. The tutorial covers various topics in React, JavaScript ES6 and Redux to give you a great start in those topics.

With Redux (like React), understanding why you’d want to use it is much more interesting than how it works.

Because the saga effects only construct a special object that is consumed and executed by the middleware (aka they dont do much!), it is really easy to test your sagas with no mocking required.

The most common Redux mistake is to mutate data in the reducer. What is mutable data, why can it lead to bugs and what can you do to avoid it?

Every developer will get to a point when they’re working where they’re going to have to debug their code.

Redux is a tiny Javascript library that manages the state of your application in a more consistent and practical way.

In this guide, I’ll introduce you to a framework known as Redux, which can help you build complex projects in a way that’s easy to scale and maintain.

In the code base I work on, we are doing an evil thing. Something that shouldn’t be done. We are making dispatch calls in React lifecycle methods such as componentWillReceiveProps, componentWillUpdate, and componentDidUpdate.

Is everything perfect with Redux? Not quite, as Redux is based on the “exotic” functional programming approach, it may be wrongly used. This article targets developers planing to use Redux at scale.

When coding complex Redux applications, you can come to a situation where you have more than one potential solution to a given problem.

Facts about React that should be known before using Redux (or MobX). Most important: Learn React first, then opt-in Redux but only if you need it. There are various techniques in React.js for scaling your local state management.

Today it’s time for the combineReducer function.

A couple of basic setup steps to use Redux combined with Redux Saga in Next.js. Whereas Next.js enables you to build server-side rendered React applications, Redux and Redux Saga make sure to handle your state not only on the client-side, but also on the server-side.

Over the course of developing these interfaces, we have arrived at some helpful rules and tips to keep Redux manageable.

Async/Ajax being in the advanced section of the official documentation can make developers afraid or hesitant to start learning about it.

Using Redux or MobX in your React application? The article shows you all the differences between both state management libraries that can be used in React.

Now it’s time to code the function that connects Redux to React!

A different learning strategy is to code a simple Redux yourself to develop a deeper understanding of the fundamental principles of the library.

I thought it would be fun to dig into Twitter's Redux store, and see how in the hell they organize all them tweets in their state tree.

People often choose Redux before they need it. “What if our app doesn’t scale without it?”

Redux is one of the hottest libraries in front-end development these days. However, many people are confused about what it is and what its benefits are. As the documentation states, Redux is a predictable state container for JavaScript apps. To rephrase that, it's an application data-flow architecture, rather than a traditional library or a framework like Underscore.js and AngularJS

redux-saga is a fairly new library in the Redux ecosystem, one that has quickly gained adoption and traction in the community.

Let's talk about how React fares in the real world when 'the business' gets involved.

If React is designed for the view layer, and we’re using Redux or something similar for the state, then where does the business logic go? This talk looks at the different options and tries to answer that question.

Functional reactive programming is based on the idea that applications can be built around streams. The structure TypeScript imposes provides us with a declarative syntax that gives semantic meaning to the streams of events and commands our application uses to build state in redux architecture.

Shruti Kapoor, Software Engineer at PayPal, and Perumal Palani, Member of Technical Staff - 2 at PayPal, walk through the decisions of moving from Redux to GraphQL.

In this talk I will show some bad practices and techniques with Redux, and how to avoid them. We will cover aspects such as code reuse, coding conventions, and architecture.

I used to use Redux with React all the time, but lately I've been using different libraries. Why do I no longer use Redux and what do I use instead?

Do you test actions, reducers, selectors, and components in isolation as unit tests? Or do you test the connected components with the actual store wired up as integration tests? Here are my thoughts.

Same app, 2 state management libs. Redux is super explicit, MobX fits in one file.

Here's a few tips and tricks I learned about Redux over the years.

Redux with its actions and reducers and elegant store is great. But what makes it really shine are thunks. Thunks are great.

So what does Redux actually _do_ when you do your reducers and your actions and connect things to the store?

So you know WHY you'd wanna use Redux and when. But how?

You've heard of Redux haven't you? It's great and everyone's using it. But why? When? Does it always make sense to reach for Redux?

Redux Thunk is the most used library for side effects and asynchronous calls in Redux - and that's for a reason.

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, I would like to address what is by far, the most asked question on Sketch Elements: Why do you use MobX? I'm excited to give my take but also to hear your thoughts on that topic.

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.

Today we'll be taking a look at a really cool library called Rematch. People who are new to react tend to find that learning redux can be a pain. Rematch makes using redux pretty painless and really simple!

Redux is a predictable state container for JavaScript apps.

Forms are hard in any framework, but they are extra complicated in React due to the recommended method of using "controlled inputs", inputs where all of their state is managed by the developer, not by the DOM or the React framework itself.

In this talk, Dan reflects on the past, present, and future of Redux.
