NPM Vulnerabilities Alert.

I installed a module yesterday MMM-MoonPhase and after I ran npm install I got a whole host of alerts talking about high severity vulnerabilities tied to underscore.js
NPM also offered up a solution npm audit fix --force which I ran. It took me a little bit to figure out what I was being told and I can’t replicate because it appeared to resolve those vulnerabilities.
What I perceive the below to be telling me is that if I am using underscore from version 1.3.2 to 1.12.0 that is where the vulnerability lies. I installed underscorejs version 1.13.1 so I should be in the clear?

pi@mirror:~/MagicMirror/modules/MMM-MoonPhase $ npm audit
# npm audit report

underscore 1.3.2 - 1.12.0
Severity: high
Arbitrary Code Execution in underscore - https://github.com/advisories/GHSA-cf4h-3jhx-xvhq
fix available via `npm audit fix
node_modules/nomnom/node_modules/underscore
nomnom >=1.6.0
Depends on vulnerable versions of underscore
node_modules/nomnom

2 high severity vulnerabilities

To address all issues, run:
npm audit fix

@ankonaskiff17 nothing we can do to suppress the messages or fix the problems…
many times running audit fix causes more trouble than not…

don’t do it, just ignore the messages

@sdetweil Is there a way to tell what libraries, dependencies, files, whatever, that a given module is using?

sdetweil

@ankonaskiff17 well, only the top level… look in the node_helper.js for require(…)

but you would then have to check every one of those dependencies, and those, and those and …

and somewhere in there may be a change that causes a particular lib to break …
cause breaking changes are allowed and common now

@sdetweil That MMM-MoonPhase module just seems hugely bloated compared to the rest of the modules. It’s like writer used some pre-built package to write module and most of it is not being used.
Was wondering how to remove some of that, I know how to comment out a line of code. Is there a way to do same but at the directory level?
It runs so probably not worth the effort.

@ankonaskiff17 The module has loads of dev dependencies. You should probably only install prod.

@mumblebaj via

npm install --only=prod --omit=dev

the 1st (–only=prod) is the old way
migrating to the new way (–omit=dev)

both are accepted

@sdetweil Can I do that retroactively or delete module then reinstall with npm install --omit=dev and that will get rid of unused directories/files?

I should be able to just delete module & no need to mess with config.js or custom.css if that is route to take?

sdetweil

@ankonaskiff17 yes just delete the node modules folder in the module folder and redo the npm install

no guarantee it will change the results

best just to ignore the messages
