If you plan on cloning this app. You will not be able to "npm run build" this app because of a npm package: terser had previous code breaking changes. Terser-webpack-plugin must use an older version 3.14.
OR
Do what I did and go into the NODE_MODULES folder after you "npm i". Open the "terser-webpack-plugin" folder and go into dist and go open the minify.js file. Proceed to line 175 and change '_terser.default.minify' into '_terser.minify'
Then you can npm run build and it should all work!
To run this:
npm i- open terser-webpack-plugin folder and go into dist and open minify.js changing the above text on line 175.
npm start
