$ npx create-react-app rpn-calc-electron
Now cd to this new directory and install electron:
$ cd rpn-calc-electron
$ yarn add -D concurrently cross-env electron electron-builder electronmon wait-on
Now copy the files in this directory to the projects folder we just created. Rename the "rpn-calc-sources" directory to "src".
You can list the availaible scripts by:
$ npm run
To run a build for a Linux Appimage and Windows App EXE:
node_modules/.bin/electron-builder -wl
