@steveb8n you can’t have more than one react since they will fight over control of the dom. typically, libraries specify a minimum version of react, not a specific version

cljsjs is annoying precisely because of the shared dependency problem.

if you plan on using a number of react libraries, I personally will direct you to one of two techniques: (1) bundle all your js with webpack or (2) use shadow-cljs

so npm-deps is the way to go? with an explicit react version in lein?

ok, thx. I’ll look at shadow, have heard good things

I would urge against npm-deps, which tries to do closure optimization and is an experimental feature with lots of limitations and unhelpful error reporting

much appreciated, this could save me a lot of time

this is my view on the whole thing with some background to help you choose: https://gist.github.com/jmlsf/f41b46c43a31224f46a41b361356f04d

hop into #shadow-cljs if you have trouble

can anybody answer this question https://groups.google.com/forum/#!topic/clojurescript/E7H1cuZQpys ? how to extract metadata of foreign-lib dependencies in self-hosted cljs

@sonnyto I posted some links to some code you can look at in the mailing list

@mfikes thanks! you're awesome

I'm using transit, but I'm running into problems when I want to use it together with [cljs-time.core :as time]

> (t/write (t/writer :json) (time/hours 1))
#object[Error Error: Cannot write ]
   cognitect$transit$write (jar:file:/home/storage/mvn/repository/com/cognitect/transit-cljs/0.8.256/transit-cljs-0.8.256.jar!/cognitect/transit.cljs:278:11)
nil
> 

> (time/hours 1)
{:years nil,
 :months nil,
 :weeks nil,
 :days nil, 
 :hours 1, 
 :minutes nil, 
 :seconds nil, 
 :millis nil}

what am I missing? Why does transit has problems with serializing cljs-time.core/Period?

I’ve no idea about transit, should write return a string? How do you specify where to write?

write should return a json string, right.

Something about numbers perhaps?

I see on the Readme that it uses (t/integer 1), presumably to maintain precision?

it seems it has to do something with types.

numbers etc don't seem to be a problem

but (time/hours 1) returns a cljs-time.core/Period-type.

See “writing custom values” here: https://github.com/cognitect/transit-cljs/wiki/Getting-Started

Right... makes sense. thx.
