cljs.main rebel-readline

Start cljs.main with rebel-readline:

clojure -Sdeps '{:deps {github-mfikes/cljs-main-rebel-readline {:git/url "" :sha "27b82ef4b86a70afdc1a2eea3f53ed1562575519"}}}' -i @setup.clj -m cljs.main

Browser REPL stress test

Run the test.clj below in a Clojure REPL, adjusting the cmd vector as needed to launch things.

It will launch the browser REPL and imitate a user typing forms into it. (If you don't have Safari set as your default browser, you can splice ["-ro" "{:launch-browser false}" "-r"] into the end of the cmd vector and launch Safari manually, pointing it at http://localhost:9000

In your browser open the JavaScript console to see progress.

A faster verzion, zippy.clj eliminates the JavaScript console logging and the Thread/sleep calls, evaluating the sequence of integer forms as quickly as possible.

To instead compare with Figwheel, do

Figwheel light ideas

It would be interesting if Figwheel could essentially decorate any implementation of IJavaScriptEnv, taking on the responsibility of watching the filesystem (perhaps even delegating that to ClojureScript :watch, and expanded :watch-fn, and perhaps minimally calling IJavaScriptEnv -load when Figwheel determines it is needed.

Then, for those REPLs that can participate, if IFigwheelSupport can be extended to them, they can do further cool stuff. (Perhaps IFigwheelSupport is actually necessary while IJavaScriptEnv as described in the previous paragraph is insufficient, and a more fancy impl of -load is needed?)

That way, things like the existing Node REPL could be minimally supported by Figwheel, as well as Ambly, the Browser REPL, etc.

What does IFigwheelSupport do?

Perhaps somewhere there is a HUD interface and Figwheel can ask a REPL to display things on its HUD? An iOS or Android-specific REPL could delegate to Objective-C or Java that implement a HUD using platform-specific UI widgets

* This example renders your top ten most followed friends/followers, `filter`ing

* With ReactJS, any time your data changes, the UI is always brought up to date

* `render` describes.
