title: Does React.js require to have a node_modules folder to run?
body: <p>I am asking this question, because I installed react for a project, I made some changes as usual, I received the error message below. I searched to see where that error was coming from, and one of the solution was to delete the node_modules folder from react, and then run npm. </p>
  
  <p>I did that, and now it is working. But, I am checking the frontend folder and the node_module folder is not there. There is only one node_module folder, but it is in the backend folder. </p>
