Hi HN!
Thanks for your attention to my post.
It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it.
Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users.
I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work.
