Redux Tutorial: An Overview and Walkthrough with React + Redux Toolkit

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.

Prerequisites

You must already know how to use React for this tutorial, as I will not be explaining any aspects of React itself.

Familiarity with HTML & CSS.
Familiarity with ES6 syntax and features.
Knowledge of React terminology: JSX, State, Components, Props, Lifecycle and Hooks
Knowledge of React Router
Knowledge of asynchronous JavaScript and making API calls

Also, download Redux DevTools for Chrome or for FireFox.

Goals

In this tutorial, we will build a small blog app. It will fetch posts and comments from an API. I’ve created the same app with both plain Redux, and Redux Toolkit (RTK), the officially sanctioned toolset for Redux. Here are the links to the source and demos of both the plain and RTK versions.

React + Redux Application (Plain Redux)

React + Redux Toolkit Application

Note: The applications are pulling from a real API via JSON Placeholder API. Due to rate limiting on CodeSandbox, the API may appear slow, but it has nothing to do with the Redux application itself. You can also clone the repository locally.

We will learn:

What is Redux and why you might want to use it
The terminology of Redux: actions, reducers, store, dispatch, connect, and container
Making asynchronous API calls with Redux Thunk
How to make a small, real-world application with React and Redux
How to use Redux Toolkit to simplify Redux app development

What is Redux?

Redux is a state container for JavaScript applications. Normally with React, you manage state at a component level, and pass state around via props. With Redux, the entire state of your application is managed in one immutable object. Every update to the Redux state results in a copy of sections of the state, plus the new change.

Redux was originally created by Dan Abramov and Andrew Clark.

Why should I use Redux?

Easily manage global state - access or update any part of the state from any Redux-connected component
Easily keep track of changes with Redux DevTools - any action or state change is tracked and easy to follow with Redux. The fact that the entire state of the application is tracked with each change means you can easily do time-travel debugging to move back and forth between changes.

The downside to Redux is that there’s a lot of initial boilerplate to set up and maintain (especially if you use plain Redux without Redux Toolkit). A smaller application may not need Redux and may instead benefit from simply using the Context API for global state needs.

In my personal experience, I set up an application with Context alone, and later needed to convert everything over to Redux to make it more maintainable and organized.

Terminology

Usually I don’t like to just make a list of terms and definitions, but Redux has a few that are likely unfamiliar, so I’m just going to define them all up front to make it easy to refer back to them. Although you can skip to the beginning of the tutorial section, I think it would be good to read through all the definitions just to get exposure and an idea of them in your head first.

I’ll just use the typical todo application, and the action of deleting a todo, for the examples.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

Performance: It delivers optimal performance.
Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
UI design: React Native enables you to design simple and responsive UI for your mobile app.
3rd party plugins: This framework supports 3rd party plugins.
Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
Near-native user experience: React Native provides several native components, and these are platform agnostic.
The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Reduce Redux Boilerplate Code with Redux-Actions

Redux has become one of the most popular libraries in front-end development since it was introduced by Dan Abramov and Andrew Clark in 2015. They designed it as the successor for Flux, with the support of some developer tools and a few more concepts embedded in it.

Flux is a fancy name for observer pattern further modified to support React. Both Flux and Redux consist of similar concepts like Store, Actions (events in the application). In other words, Flux is a simple JavaScript object but with some middleware like redux-thunk. It can be a function or a promise for Redux. However, Redux is a single source of truth with concepts like immutability, which improve performance. It is one of the main reasons for Redux to dominate in State Management.

Despite its advantages, some developers have found it rather challenging to deal with Redux due to the amount of boilerplate code introduced with it. And the complexity of the code seems to be another reason for the difficulty.

In this article, we will look at how to reduce the boilerplate code brought about by Actions and Reducers using Redux-Actions
