Trying to make sense of all the Tooling & REPLing (mostly Clojurescript)

[Andy R]

Hi *,

I'm trying to wrap my head around all the tooling+REPL in Clojurescript. I haven't really been able to find a good overview of the currently used tools/plugins.
I find it very tough to understand how everything plays together: REPL, nREPL, Middelware, Weasel, Piggieback, bREPL, CLJS->JS conversion, Emacs, Cider, cider-nrepl, Browser, JVM, Editor.

I don't expect other to just explain everything to me so I did a brain dump of what I've been able figured out:

https://github.com/rauhs/clojurescript/wiki/Clojurescript-Tooling-REPL-overview

I mostly wonder if the section "cljs.repl/repl" is all correct. Also the very last section ("A typical setup") I do some hand waving since I don't really understand how everything is tied together.

This might also help other newcomers to understand how everything plays together (if my write up is mostly correct). I think it would also be helpful to have such a page somewhere as a living document.

I'd love to get corrections (either here or in the wiki) of the things that I misunderstood.

Thanks for reading

For clojurescript, for me, I'm on Emacs, I use figwheel.  I have it running in an inf-clojure buffer.  I have a function in my .emacs with:

(defun figwheel-repl ()
  (interactive)
  (run-clojure "lein figwheel"))

See this post for details:

In your list of items:

REPL, nREPL, Middelware, Weasel, Piggieback, bREPL, CLJS->JS conversion, Emacs, Cider, cider-nrepl, Browser, JVM, Editor.

I only think about care about:

REPL (via figwheel)

CLJS -> JS conversion comes about with cljsbuild setup in project.clj.  Some entries I have in that are:


Then just point your browser to:

After you run figwheel-repl in emacs.
