I’m of a bit of an opposite mind on the many, and usually very public, NPM security issues. Because from my experience the JS ecosystem, and it’s woes, teach a lot of people to never trust the part of their operation that is coming from someone else. I mean not everyone, obviously, but in my anecdotal experience it’s far more common to see good package control and review processes for JS than any other language, well except for maybe Python when the Python is done by software engineers and not “data-scientists”.
Supply chain security is immensely important, and I encourage you not to learn about it the hard way like I did. Which somewhat ironically happened in the .Net ecosystem when one of our trusted Nuget packages got hacked many years ago. Now, I could be mistaken and I hope I am, but I suspect that if you ask a Java, a JS and a C# developer if they trust their ecosystem, then only one of them is likely to say yes.
So no, there won’t be some great revelation in the JS community. The best you can hope for with stories like these is that fewer developers feel like imposters when they realise that GitHub stores plaintext security assets in their logs.
