This is the code made for the tutorial I made: Creating multiple React applications on a CMS website or on a static website. The intention for this tutorial is to implement React Application inside CMS or static websites that are not built with as a single page application.
To follow the tutorial you have to have NodeJS installed. You can follow this tutorial also with yarn.
This tutorial will help you to understand how to implement React applications on different architectures, which is useful when you make applications to be reused on multiple sites.
