Note for future upcomers:

1. One needs to change name field in package.json to get the app run.
2. If using nuxt.config.ts not js for nuxt project, you need to fix the main.js file to properly import nuxt.config.ts or otherwise you can simply delete the line and set the dev variable to true/false manually to get the project running
