Question

I apologize for this seemingly stupid question, but I’ve been playing with ClojureScript on and off for a few weeks now, and I can’t figure out this one simple question:

How do I debug ClojureScript?

So here is the problem:

1. I write my *.cjs files
2. I run cljsc/build …
3. I load up my webpage.
4. Something bad happens.
5. I open up the firefox console.
6. I get a line in the generated js, which I find incomprehensible, and I have no idea which line of the original cljs file it came from.

My question:

What is the right way to develop ClojureScript applications?

PS I’ve looked at ClojureScriptOne — what I don’t like about it is that it strings together a bunch of technology all at once; and I’d prefer to understand how to use each individual piece on its own before chaining it all together.

I’m comfortable with ring + moustache + compojure, [mainly because I can use my standard Clojure debugging techniques] but ClojureScript is another beast.

UPDATE: Things have changed quite a bit since this question was first asked. The proper way to debug ClojureScript applications these days is to enable source maps – http://github.com/clojure/clojurescript/wiki/Source-maps

Answer 1

UPDATE: I’ve taken the liberty to change the original answer since it is so woefully out of date and I cannot unmark this answer and mark a new one.

To debug ClojureScript use source maps – https://clojurescript.org/reference/source-maps
