Hi list,

I started working with NodeJS quite recently, even if at first I was a
little skeptical about it, after using it intensively for the last
couple of months I realized it's an amazing piece of technology. The
only thing that I miss from other frameworks is the concept of
thread-locals.

After some time researching on this, a friend told me that this
behavior could be achieved using domains [0]. I built a small
framework, Kolba [1], as a proof of concept of how I see this being
implemented. I also wrote an article explaining this idea and
presenting some questions that I have.

The main question that I want to ask here is: What am I missing? Why
is this undocumented? Are there any edge cases that I don't see, which
make this idea non-viable?

Actually, the biggest problem I'm facing with the use of domain is the
suppression of exceptions. I may be using it wrong probably, which
leads to errors being silenced, but nothing regarding the emulation of
thread-locals.

Thanks,
