I cloned Biff cd’d to example did ./task setup ./task dev - got repl connected, and did a build of app but nothing at localhost:8080 got some warnings in terminal but nothing looked fatal. Did I miss something?

no, that should be everything. Did you see a System started message in the terminal? Could you check if there's a file at biff/example/www/localhost/index.html? Would you mind pasting the output of ./task dev here?

Everything looks good in that output. Going to localhost:8080 should serve files from biff/example/www/localhost/. Is there an index.html file in that directory?

retried checked index.html - it contains a login form did a force compile in the shadow-cljs dashboard - no error messages - after a fairly long wait I get a 404

I think I've found the issue. I've pushed a new commit to Biff. Set :sha to "668ebd1ade0abf57ec5963a23fa8678819e5cb1e" in biff/example/config.edn and try running ./task dev again. The update (https://github.com/jacobobryant/biff/commit/668ebd1ade0abf57ec5963a23fa8678819e5cb1e) sets the default port to 8080 instead of nil. Immutant is supposed to default to 8080 anyway (and it has been for me at least), but evidently that's not happening in your environment for some reason.

That helps but I get a “not found” at http://localhost:8080/index instead of a login

ok, progress at least. Can you add the following :example/debug component to example.core/components?

(def components
  [{:name :example/debug
    :requires [:biff/web-server]
    :start (fn [sys]
             (prn (select-keys sys [:biff.web/host->handler]))
             sys)}
   {:name :example/core
    :requires [:biff/init]
    :required-by [:biff/web-server]
    :start start-example}])

actually hold on for a second, I may need to update that component

ah I got the :requires field wrong. I've edited the code sample; go ahead and try that.

this is the output I get:

#:biff.web{:host->handler {"localhost" #object[ring.middleware.ssl$wrap_hsts$fn__13477 0x56cdcae6 "ring.middleware.ssl$wrap_hsts$fn__13477@56cdcae6"]}}
