Is it possible to use re-frame without react, and in Clojure (not cljs)?

I have a curses-ui use case, maybe.

well, re-frame does depend on reagent for it’s reactivity.

but re-frame itself is CLJC

you’ll need to come up with your own way of subscribing and propagating updates to parts of your app

FWIW I have a couple codebases where I ripped out all of reagent from re-frame and just use the event and effects system and it works quite well for my needs

You mean, like the ratom stuff? That's what I'm hoping to use from re-frame.

yes, like the ratom stuff

the ratom stuff all comes from reagent

ohh, right

and reagent is cljs-only

Trying to add re-frame-10x to an existing cljs project and I’m seeing the following error:

----  Could not Analyze  resources/public/js/compiled/out/day8/re_frame_10x/subs.cljs  ----

  No such namespace: mranderson048.re-frame.v0v10v2.re-frame.core, could not locate mranderson048/re_frame/v0v10v2/re_frame/core.cljs, mranderson048/re_frame/v0v10v2/re_frame/core.cljc, or JavaScript source providing "mranderson048.re-frame.v0v10v2.re-frame.core" (Please check that namespaces with dashes use underscores in the ClojureScript file name)

Deps:

[cljsjs/react "16.4.1-0"]
[re-frame "0.10.6"]
[day8.re-frame/re-frame-10x "0.3.4-react16"]
[reagent "0.8.1"]

:profiles :dev :dependencies contains [day8.re-frame/re-frame-10x "0.3.4-react16"]

Can you try lein deps :tree and see what it recommends? (Assuming you’re using lein)

sounds like a version mismatch somewhere

:cljsbuild :builds :compiler contains :optimizations :none and :closure-defines {"re_frame.trace.trace_enabled_QMARK_" true goog.DEBUG true}

@manutter51 Will do

I’ve got one version of re-frame and one version of re-frame-10x in the deps tree. I see no mention of mranderson which sounds like the problem.

Seems like lein should be pulling that dependency since it’s mentioned in the :plugins for re-frame-10x.

Do you have any recommended exclusions for reagent or re-frame?

Negative

Also, are you sure you need to include [cljsjs/react "16.4.1-0"]? We’re not using that in our re-frame project

I’m not sure if we need to use that version, happy to try and different one. What version do you use?

We don’t have a reference to react at all, we just let re-frame/reagent pull in what they need.

For reference, here’s bits of what’s in our current project:

:dependencies
                 [org.clojure/clojure "1.9.0"]
                 [org.clojure/clojurescript "1.10.238" :scope "provided"]
                 [re-frame "0.10.5"]
                 [reagent "0.8.0"]
   ...
:profiles
  {:project/dev
    :dependencies [
                                [day8.re-frame/re-frame-10x "0.3.3"]
                                [day8.re-frame/tracing "0.5.1"
                                 :exclusions [[org.clojure/clojure]]]

I tried removing the [cljsjs/react "16.4.1-0"] dep, still fails in the same way. Upgraded Leiningen too.

I’ll try matching your exact versions to see if that solves it.

That worked! Thanks @manutter51. There must have been some type of version mismatch issue.

Cool :thumbsup:

It’s the version of re-frame-10x. When I bump it to day8.re-frame/re-frame-10x "0.3.4" I see the error.

Interesting

Figured it out from the CHANGELOG

[0.3.6] - 2018-12-11
Fixed broken merges in 0.3.4 and 0.3.5 when updating the bundled version of re-frame.

[0.3.5] - 2018-12-06
Fixed
Attempted to fix the namespaces when updating the bundled version of re-frame, but we didn't fix everything, so this release should not be used.

The latest version mentioned in the README is 0.3.4 however the latest version in the CHANGELOG is 0.3.6. I just confirmed that 0.3.6 works, looks like a simple PR to the README.

Hi, I am just trying out 10x. I have deps: ` :dependencies [[org.clojure/clojure "1.9.0"] [org.clojure/clojurescript "1.10.238"] [org.clojure/core.async "0.4.474"] [figwheel-sidecar "0.5.15"] [re-frame "0.10.6"] [day8.re-frame/re-frame-10x "0.3.4-react16"] [reagent "0.8.1"] [orchestra "2018.09.10-1"] [district0x/re-frame-spec-interceptors "1.0.1"]]`

No errors showing but ctrl-h doesn't bring up the console.

(it is still ctrh-h on a MAc is it not?

Oops, no, I am getting No such namespace: mranderson048.re-frame.v0v10v2.re-frame.core, could not locate mranderson048/re_frame/v0v10v2/re_frame/core.cljs, mranderson048/re_frame/v0v10v2/re_frame/core.cljc, or JavaScript source providing "mranderson048.re-frame.v0v10v2.re-frame.core"

dropping to [day8.re-frame/re-frame-10x "0.3.3-react16"] fixed it

That’s the same issue I was seeing @tomayerst. If you use 0.3.6 you shouldn’t see that error.

Yeah, just read back and trying that now

PR to fix the README here: https://github.com/Day8/re-frame-10x/pull/227

sweet! [day8.re-frame/re-frame-10x "0.3.3-react16"] works. Right, back to @ericnormand and "Understanding Re-frame" 😀

Can someone refresh my memory. There was a way to pull a sub value in an event-fx, right? Similar to :<- syntax for subs

I guess It came out a bit confusing… so what I want is something like this:

(rf/reg-event-fx
  ::foo
  :<- [:bar]
  (fn [{:keys [bar} _] ,,,, )

I can of course access :bar by getting it directly from db, but the point is to use existing sub

I've only seen it done with an interceptor using a third party library

https://github.com/vimsical/re-frame-utils/blob/master/src/vimsical/re_frame/cofx/inject.cljc

https://github.com/Day8/re-frame/blob/master/docs/FAQs/UseASubscriptionInAnEventHandler.md

yeah.. that’s I think what I was looking for… Thanks!

@ag sounds like you might be after the path interceptor? Maybe.

I'll mention it just in case. It doesn't inject subscriptions but it does narrow the value within app-db which is supplied, like update-in

Search for path in here to see it used and explained: https://github.com/Day8/re-frame/blob/master/examples/todomvc/src/todomvc/events.cljs

hi everyone. i'm using re-frame and figwheel. when i change any component's render method, it seems like every component gets re-mounted (via figwheel calling my reload fn, which just renders base component). is that expected?
