add parent

Actually, the deprecation warnings are with npm install but are gone with:

npm --silent install

so xb-demo can use that.

Code is here:

and I relayed to Adam

kristen pol → credited phenaproxima → .

https://github.com/phenaproxima/xb-demo/pull/36

kristen pol → changed the visibility of the branch 3514456-suppress-npm-warnings to hidden.

That MR was wrong... here's the correct one:

https://github.com/phenaproxima/xb-demo/pull/38
