A yhwh-script project with SQLite WASM built on 
Just call npm install and npm run dev.
You can create Single File Web-Components in dedicated .html files inside the public/elements folder. npm run dev and npm run build will generate maps in src/elements/index.js which are being fetched in the /src/main.js script for defining your CustomElements.
Please understand that the project structure is leaned on valid-custom-element-names, i.e. using a dash ("-") is mandatory.
In /src/publicApis/index.js you can define APIs for your custom-elements (for example to the SQLite module) via the window object.
Just stick to the examples and you are good to go. Have fun!
