Recently react released their updated Create React App CLI. They are finally catching up a little to what nuxt offers out of the box and IMO still ways away. However, one item really stuck out - the Error Debug Overlay https://facebook.github.io/react/blog/2017/05/18/whats-new-in-create-react-app.html#runtime-error-overlay
Nuxt does provide something of an overlay but can definitely be improved. Now I suspect this is not an easy feature to develop but I wanted to bring it up to the community as I believe it would bring immense value.
Debugging experiences differ a lot between languages and stack. When I first hand experienced better errors from Ruby's padrino stack, I was blown away. REPL loads on uncaught errors and you can debug live.
