I have a couple questions on the results that DepCheck returns for "Missing Dependencies" (screenshot below)

• How do Node_Modules exist for most of these dependencies returned, even though they are not listed in package.json ? Some of these missing dependencies (Service worker dependencies, for example) are not breaking my app (to my knowledge)

• Is it correct that the fix for these is to simply "npm i" them one at a time?

Thanks!
