@cnryb why are you use this package? it's only use for some case of backend-only like node side.

[cnryb]

I want to understand how weex debugging works.
But the corresponding documentation is missing.
So, I try to run the code here.

@erha19 When I execute weex debug, it seems that this package is not used.
Under what circumstances will this package be used?
