Install ReactJS Tools

The first thing you’ll want to do is set up your environment to run React apps. Most of the development tools for React are available for free. Let’s start with your development environment. - A browser that supports modern JavaScript features. Currently, only Chrome and Firefox support these features, so you’ll need to use one of those browsers to get started. - A code editor that supports ES6 syntax. Currently, only Google’s editors - Google Code and Notepad - support ES6, so you’ll need to use one of those to get started. You can also use a third-party code editor. - A project management tool that allows you to manage multiple projects. The following tools have been used in this guide to manage multiple projects: GitHub, Bitbucket, Gitlab, or Atlassian’s Jira.


Create a New Project in Node.js

Now that you’re set up and have installed the required tools, you’re ready to install React. There are several ways to do this: If you already have a Node.js project, you can simply install the React package with npm install -g react. Otherwise, you can create a new project and install React with npm init -y. In this new project, you can then install React with npm install react.

Learn React Basics with JSX

The goal with React is to create a view that is then rendered to the screen. A view is like a webpage or application. It shows the content, but it’s also responsible for showing headers and navigation. React provides a syntax similar to HTML where you can create a component and then add elements to it. A component is the basic building block of React. It handles all the logic for displaying the view. A component takes in data and then updates the view when the data changes. JSX is a syntax extension to the JavaScript language that’s used to create React components. It’s similar to HTML in that you create a component called MyComponent/> in JSX syntax. MyComponent/> is then used as a template for creating the component. Here’s an example of how you create a component with JSX:


Add UI Components to our App

Now that you have a basic understanding of what a React app looks like, let’s create the basic user interface. We’ll start with a header and some buttons. We’ll use the Header/> component to render the header, and Button/> to render the buttons. We can then use JSX syntax to create a wrapper Content/> component that renders our content. Here’s a basic UI using the components we created: Now that we have a basic UI, let’s go back to our app and add the Header/> component to render the header.
