Create Your First React App In Easy Steps

Originally published by Adesh at zeptobook.com

What is React?

 Unlike Angular, which is a framework (or a complete solution), React is essentially a ‘view library’. It only takes care of the view or what is rendered in the DOM. It doesn’t have an opinion about other aspects of an app such as routing, calling HTTP services, etc. For those concerns, you need to use other libraries. This means you get the freedom to choose the libraries that you’re familiar with or prefer.

React is Declarative

With the help of React, you can make very interactive UI without much pain. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes.

Declarative views make your code more predictable and easier to debug.

React Components

Components are the building block of React apps. A component is a piece of UI. It has data and describes what that piece of UI should look like. When building React apps, we build a bunch of small, independent and reusable components and compose them to make complex UIs. So every React app is essentially a tree of components. If you’ve worked with Angular 2+, this should sound familiar.

React is Component-based Architecture

React is based on component based architecture. You can build encapsulated components that manage their own state, then compose them to make complex UIs.

Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep state out of the DOM.

Reusable Components

You can develop reusable components without much hassle.

Prerequisites

We’ll assume that you have some familiarity with HTML and JavaScript, but you should be able to follow along even if you’re coming from a different programming language. We’ll also assume that you’re familiar with programming concepts like functions, objects, arrays, and to a lesser extent, classes.

Setting up the Development Environment

Before going to create your first react app, let’s first setup the development environment.

First check, whether you have Node.js an NPM installed in your machine. You can go to nodejs.org and install Node, if you don’t have.

Once you have installed Node and NPM in your machine, choose your code editor. Feel free to use any editors you prefer. My preferred editor is Visual Studio Code/VSCode which you can get from code.visualstudio.com

npx create-react-app my-app

This command will create my-app folder having react app files. Now, go to my-app folder and type this command.

cd my-app

Now, type this command to run your react app.

npm start

This command will show below message in your terminal window, and open the app in browser window. The app url will be http://localhost:3000/ in your browser tab.

React App Project Structure

Now, open your code editor, here I have Visual Studio Code, so I am going to open our my-app in the VS Code editor to see the react app project structure.

This is very basic project structure.

You will have node_modulespublic and src folders in the root of the my-app folder. Along with these folders, you can see package.json file as well.

  • node_modules: where all the 3rd-party dependencies (libraries) are stored. We never have to touch this.
  • public: where we have public assets of our app such as index.html, logo, images, etc.
  • src: where we have the source code of our React app.

Open up package.json. Chances are you’re already familiar with this file. If not, package.json is like an identification card for a project. It includes the project’s name, version, dependencies, etc.

Note that under dependencies, we only have 3 dependencies:

Next is the index.html page, located in the public folder. If you do link up any external stylesheets, or need to add bootstrap, or another feature, this is where you would add it.

You can also change the title here. Other than that, you won’t usually need to touch this file very much. You will also notice the div with the id of “root”. This is where all of the content will be output. You don’t need to change that, but just know that it’s there.

The next file you may want to look at is your index.js file in the src folder. Here, we’re importing React and the ReactDOM. We are also rendering everything here to the root element.

Create Your First React Element

Now, we are going to create our first react element. So, first of all, delete all files from the src folder, and create a file index.js in same folder.

Write the below mentioned code in this file, and save the file.

import React from 'react';
import ReactDOM from 'react-dom';

const element = <h1>Hello ZeptoBook!</h1>;

ReactDOM.render(element, document.getElementById(‘root’));

As soon as you saved your file, our first element H1 will be displayed on the browser window.

Code Analysis

Let’s have a look at above code.

On the top 2 lines, we are importing react modules.

import React from ‘react’;
import ReactDOM from ‘react-dom’;

On line 4, we are creating a constant named element, and created H1 tag inside this element.

Finally, the last line of code will render our react element.

ReactDOM.render(element, document.getElementById(‘root’));

ReactDOM.render() will render this element in DOM. If you notice, we used root as our container to render this element. You can find the root element in /public/index.html file.

<div id=”root”></div>

So, here we learn, how to setup and run our react app very easily without any hassle.

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.
