Unsubscribe in a React Component Using Redux

To use Redux state management in a React app, you can use a popular library called react-redux, a handy option to configure Redux in your app. When you use Redux, various actions can be triggered, and based on the response, data gets managed in a global state through the action subscription and unsubscription mechanisms. In this guide, you will learn about the subscribe and unsubscribe actions using Redux.

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

Accessing Redux from Components In React & React Native

How to set up a basic version of Redux in your React or React Native application. To make things clearer, I based my setup on my event application, where users create events that other users attend. We generated the action creators, reducers, and Redux store, and wrapped the application in a provider. Today I’ll finish the loop and talk about how to access the Redux store in your application using both class and functional components. The provider we added to the root component provides the store to all the components in your application. Therefore, we will just look at how to access the store from an individual component.

React Native Redux | How To Use Redux In React Native

React Native Redux Example | How To Use Redux In React Native is today’s leading topic. Redux is a standalone state management library, which can be used with any library or framework. If your background is React developer, then you have used the Redux library with React.

Overview of React Native Redux Example

• Step 1: Install React Native on mac.
• Step 2: Add TextBox and Button.
• Step 3: Define the state and input handler.
• Step 4: Create actions, reducers, and components folder.
• Step 5: Create a Reducer function.
• Step 6: Create a Redux store.
• Step 7: Pass the store to the React Native app.
• Step 8: Connect React Native app to the Redux store.

React Native Redux Example Tutorial

The primary use of Redux is that we can use one application state as a global state and interact with the state from any react component is very easy, whether they are siblings or parent-child. Now, let us start the React Native Redux Example Tutorial by installing React Native on Mac first.

We start our project by installing React Native CLI globally on the Mac. You can skip the following command if you have already installed it.

Let’s use redux in react

Redux is super simple to use. Actions are used to indicate what can be possible done to the states, reducers are used to indicate the transformation of the state, dispatch is used to execute the action and store is used to combine all together. Is it sounds like greek? let me explain in detail.

What is redux?

Redux is a state management library which can be used in React and it can be also used in Angular, Vue and even vanilla JavaScript. Apart from that Context API can be used as an alternative for Redux.

Why we need redux? can’t we use states and props? This is an additional burden.

Let me explain, If sub component has its’ own states then it is not a problem to manage them. Then what if those data is needed for the sub component two. Then we have to do **state uplifting **and pass those data to the parent component as follows and pass them to the child component as props. Then it is still manageable.

What if those data is needed for Component One and Component Two as well. Then we have to face the problem of **props drilling **as follows because we have to pass those data here and there using props and it become a burden.

Then redux come to solve this issue by separating the data from components as follows.
