How often does your webpack setup blow up? We haven’t touched our configuration in a year and it still works perfectly fine. What complex things must you be doing for you config to not even last 3 months !!!
I doubt it's my incompetence alone - npm is involved in over 25% of Phoenix's issues!
All that to say, Rails is fine. But Node is also fine, if you treat it more like Go (minimal dependencies, lean on the vanilla underpinnings).
