Great stuff! But why not just create a pull request to github.com/jenkinsci/warnings-ng-plugin to include this npm parser? I am sure a lot of people will use it.
Hi Sebastian. Yes, this is my ultimate goal. But I had to start somewhere (just to see which data can be extracted from the npm audit log, and to figure out the possibilities of warnings ng). But after your encouragement this is going to happen earlier that otherwise :)
