[ClojureScript] REPL setup help

2017-07-30 Thread Rob Nikander 
Hi,

I'm new to ClojureScript. I followed the quick start instructions [1] and 
set up a REPL. It works, but now I'd like to integrate a REPL with my web 
app and IDE. Any pointers?

I have a Java servlet container, also running Clojure code. I'm using 
IntelliJ with Cursive plugin, and have REPL windows in the IDE working for 
the JVM/server-side of things. I can reload Clojure code in the running 
server. 

Now, that servlet code responds with an HTML page which contains my 
ClojureScript code. That runs, but I don't know how to connect that browser 
environment to a REPL window in IntelliJ, or even a REPL in my terminal. 
 The quick start terminal REPL only connects to a magic server listening on 
localhost:9000. 

Anyway... any pointers? 

thanks,
Rob

The ability to consume node_modules is just an additional feature - it
makes no existing features obsolete.

[ClojureScript] Re: ANN: ClojureScript 1.9.854

2017-07-30 Thread Leon Grapenthin 
Yes, it does make CLJSJS obsolete and the new method is to include Node 
modules from NPM.

CLJSJS was never the one true way, especially for production. It lacked 
deduplication of transitive dependencies that were not packed per CLJSJS 
and of course support for dependencies that where are not included in 
CLJSJS. 
It was nice to get started quickly, but in production one compiled its own 
bundle of js deps e. g. via webpack, and handwritten (or handcopypasted) 
externs.

As a newcomer, you won't have to deal with all that in the future, which is 
one of the many benefits of this release.

Nonetheless this new functionality will probably take an iteration or two 
until its stable.

No idea, make something minimal without any tooling besides ClojureScript
and report the issue in JIRA.

Thanks,

Amazing release, trying it out right now.

Just wanted to see if including this 
works: https://github.com/coopermaruyama/react-web3

I try to :require it via [react-web3 :as w3]

Unfortunately this gives me a not-found error. Also I noticed that CLJS 
indeed downloaded react-web3 to "node_modules", but the folder is missing 
from the node_modules folder in the compilers output.

Am I requiring it wrong, or is it not supported for some reason?

Kind regards,
 Leon.
