Install necessary tools

Before we start we need to install some tools first. First we need an IDE (integrated development ebvironment) for developing our app. We recommend Visual Studio Code, which has become the most popular free IDE within the last years. You can download it at the following page:

  • https://code.visualstudio.com

Next we need Node.JS, which is the runtime environment for our React application. React apps are written in JavaScript, which cannot be executed directly by a computer. This is why we need Node.JS. Node.JS can be downloaded from the following page (you should download the LTS version):

  • https://nodejs.org/en/

After you have installed Node.JS open a terminal and type the following command and execute it:

node --version

This should print the Node.JS version number to the console if Node.JS was installed correctly. That's it. We are ready to create our first React app.
