When you start with React, it is common that you just start a project with the CRA tool. While this quickly makes a project, it also does lots of magic in the background to make it work. For learning purposes, it can be better to write your own configuration to build a react application.
Very simple setup
It is possible to use the ReactJS framework without using any transpilers. For this, make a new directory for our project and make a
index.html file containing the following content:
<html> <head> <title>My React app</title> </head> <body> <script src="react.development.js"></script> <script type="module" src="/main.js"></script> </body> </html>
