Thanks, looks good! Would be nice to also add a prettier config like

"prettier": {
        "arrowParens": "always",
        "tabWidth": 4,
        "semi": true,
        "singleQuote": false,
        "trailingComma": "none",
        "printWidth": 120
    }

Thanks for your review! We have a prettier config in the root folder which applies to all packages.

Looks good to me, but I left a few minor remarks.

[q] Why do we not check dependencies for the cap sample?

[marikaner]

[pp] Just saw the other comment - what if we just ignore the cap types lib? Depchek supports the standard definitely typed packages, but not something like this...

The thing is that, I also have to move @cap-js/cds-types back to the root package json, because if I put it in sample-cap and run pnpm install from root, it sometimes creates a symbolic link in the root node_models pointing to a directory which does not exist. (As you can see in the screenshot, sap__cds aka. ../@cap-js/cds-types simply does not exist. Maybe this path is hardcoded somehow, ignoring .pnpm)

This will also cause public-api check to fail due to this non-existing folder.

AND, this symbolic link only got created randomly. I also saw it sometimes in the pipeline causing an error for check:public-api, but if I click on re-run, it sometimes just turned green again..

So I now decide to move this dev deps in root and remove the filter in the dep check. This could be an issue of CAP.
