I've seen this same NPE in my project. I managed to work around it by
temporarily throwing out the browser repl. It seems to trigger the NPE. Not
sure how and why.

Hi Zhao,

sorry to be so late to thank you. For reasons I don't know I read your

In your expansion, :x is not a keyword but a symbol starting by a colon --
the symbol fn performs no validation on its input.
When you copied/pasted it for evaluation it was then read as a keyword.

I've debugged a bit, the underlying cause seems to be that
goog.net.xpc.CrosspageChannel uses goog.async.Deferred, which lives in
third_party.
In my project, I could indeed successfully compile again with the browser
repl, by adding the third-party jar.
This leaves two open issues:

My original reason for splitting the third-party JAR was the licensing: the
main G.Closure library is under the Apache license; the third-party
libraries are under a variety of different licenses.
One simple solution would be to make ClojureScript itself have a dependency
on the third-party lib

I concur, but maybe we could make a second release of the closure lib main
jar, with a dependency on third-party?
That would reflect the actual dependency.
I know, you asked for testing before the release. Sorry for not catching
this one.

Noir is built on top of Compojure. I guess just use what you like better.
I don't think you will use Ring directly initially. So get familiar with it
as you need to, the API is tiny.

Noir is higher level than Compojure, and usually easier for new people
to jump into, but not always as flexible, functional or composable.

It was helpful for me to start from the ground up: Got familiar with ring,
then compojure, hiccup, noir, etc. Getting familiar a library at a time
prepared me better for managing the more comprehensive frameworks when it
came time to customization. FWIW.
