How to rename a file in React?

Question

JavaScript

Hello, I had an index.js file, I renamed it to app.js, but React is looking for index.js. How do I update the project so that React starts looking for the right file?

Answer 1

find where "index.js" occurs in your project files and replace it with "app.js". at some point you will be lucky and it will work.
In general, of course, it would be nice to understand how your build system is arranged and works, and until then, do not rename anything so that it does not break.
