This zApp is designed to run in the context of zOS.
You will need to run npm run watch, and link the output folder (dist) to your local instance of zOS.
nvm usenpm inpm run watch
At this point, you should see a dist folder. This is the compiled version of your app. If you wish to import this into zOS, you will need to do the following:
npm run link [location of zOS, e.g. ../zOS]
or, if the above script doesn't work for you:
cd distnpm linkcd [location of zOS]npm link [package name of this zApp from package.json]
Check node_modules in zOS - your package folder should be symlinked in there.
