It’s good to keep them up-to-date.
That’s not really auditing, but with few as possible global packages, this should be fine enough.
there is npm-check-updates or alternatively npm-check
npm install -g npm-check-updates
check outdated global packages:
ncu -g
OR
as recommended by @pldg via npx
npx npm-check-updates -g
OR
as recommended by @wheredidthatnamecomefrom
npx npm-global-audit
this is a script running with yarn. it does a temporary copy of your current global packages. see more on their github.
this the npm way as recommended by @Henke
npx npm-global-audit --auditor npm
