envy

envy smooths over the importing of :closure-defines data from a ClojureScript project's cljs.edn file into an env var that you can use at runtime.

For instance, if we had the following in our cljs.edn file:

{
...
 :closure-defines
 {env
  "{:my.thing/instrument? true
    :server               \"localhost\"
    :port                 9999}"}
...

Then in a REPL we would be able to do (-> envy.core/env :my.thing/instrument?) and get back true.

Usage

Let's first clone the repo and launch a REPL:

git clone https://github.com/johnmn3/envy.git
cd envy

Edit the cljs.edn file to look like the above example. Then launch your REPL:

clj -m cljs.main -co co.edn -r

Now, in the REPL, let's require envy.core and try out env:

cljs.user=> (require 'envy.core)
nil
cljs.user=> envy.core/env
{:my.thing/instrument? true, :server "localhost", :port 9999}
