It sounds like you’re trying to include a file dashboard.js in HTML.

If this file contains code like require('react'); then it means that you need to first compile it using a build tool that will actually find react and bundle it together with your own code.

In case of the tutorial you’re linking, the build tool used is webpack. Your HTML should include the file generated by webpack (index.js, or whatever you have in output section of webpack config), rather than dashboard.js alone.

webpack.config.js

var config = {
   entry: './main.js',  # the main code of your app that require()s other files

   output: {
      path:'./',
      filename: 'index.js',  # the file you should be including in HTML
   },
