I was migrating StrykerJS itself to native esm yesterday. It went smoothly, very helpful error messages from #nodejs pointing you right at the solution. 💕

Nothing makes me more proud than navigating to a random open source project and seeing the most recent commit is from a colleague. #awesomesauce

Update: npm has pulled the broken versions of colors and faker. This means that the problem is solved for the time being. Both Karma and CucumberJS are pinning version 1.4.0 as we speak. Most direct problems are resolved.

@marak this is also blocking small(er) companies and other open-source developers who are spending their own free time on this. Also: news outlets are picking this up and not fully representing your side of the story. Time to roll back your changes IMHO

New versions of Colors.js and faker.js both have major and deliberate security findings! Blocking CI/CD pipelines across the world. I can understand being frustrated and angry about not getting paid for your hard work, but this is not the solution 😢! snyk.io/blog/open-source-npm…

Ok, I'm happy to get the free booster 💉. But why is the website written in AngularJS? I mean, is it the vaccine for COVID? Or the Spanish flu?

I've been working on a new feature for StrykerJS called "--ignoreStatic". Preliminary results are mind-blowing 🤯 StrykerJS's core contains 6% static mutants. Yet, testing these costs more than 50% of the execution time. Again: 🤯 See github.com/stryker-mutator/s… for more details.
