React and React Redux — Connecting to Redux

Redux is a light weighted State Management Tool that helps the components in our React App to communicate with each other. The simple concept behind this is that every state of the component is kept in a store that will be global. So that every component can access any state from that store.

In this blog, let’s see a simple example of React-Redux. The logic is to increment and decrement a number on a button click with React-Redux.

1. Creating React App and Initial Setup

Initially, let’s create a new React App. Also, check if everything is fine with the created project.

npx create-react-app reactapp
cd reactapp

Now let’s install Redux.

npm install redux
npm install react-redux
npm start

Now open http://localhost:3000/ and check if the server starts well. Now let’s create our views.

2. Designing Our View

Here, I am creating a simple React Class Component named Counter.jswith two buttons and a text where one button is for incrementing and the other is for decrementing. The incremented and decremented values will be displayed in the paragraph tag.

src/Counter.js

import React, { Component } from 'react'

export default class Counter extends Component {
render() {
  return ( 
      <div>
          <h1>Counter</h1>

          <button style={{ height: '40px', width: '150px' }}>Increment + </button>

          <p>4</p>

          <button style={{ height: '40px', width: '150px' }}>Decrement - </button>
      </div>
    )
  }
}

After creating the Counter view, I am including the Counter component in my App.js file.

src/App.js

import React from 'react';
import logo from './logo.svg';
import './App.css';
import Counter from './Counter'
function App() {
  return (
    <div className="App">
      <Counter />
    </div>
  );
}
export default App;

Now open your browser and navigate to http://localhost:3000/. You must see something like this.

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.

A Basic Redux Setup in React/React Native

Redux is a powerful state management tool that can be very useful as your React or React Native application grows and requires you to keep track of more state. How you want to set up Redux is up to you, but if you’re a beginner, it may be easiest to learn the flow of Redux with a step-by-step walkthrough. Here I’ve outlined a basic way to set up Redux to go along with this post and it will be the same for React and React Native.
