A luxuriously simple and powerful way to make front-ends with DataScript and Reagent in Clojure.
@theronic I don't think anyone has done this yet, but there was a bunch of refactoring that extracted most of the stateful bits of things so that someone could add a rum plugin fairly easily. If you're interested in hacking on that, I'd be happy to point you in the right direction there.
@mpdairy I have an auto deploy config with
travis ci for one of my projects. I didnt setup the auto deploy myself but I think that the file is pretty self-explanatory. The only things that you would need to change are the your encripted env vars and your release config in project.clj. Links below

Hi, I'm trying to get re-posh working with my app, but my pretty simple req-query-sub seems to be causing an "Assert failed: (db?db)" exception. Not sure what's going on. I was pulling in the datascript conn via mount, removed that, still have the problem, and did some mucking around and determined that calling connect! without a valid conn, throws an assertion there. So it seems like as of connect! things are fine. unfortunately the stack trace isn't really helping me figure out whats going on. I tried the query with and without ':in $' to no avail
figured it out, but not sure what the problem is. When I got rid of the pull, everything was ok. But I'm not sure why pull isn't happy. been over the DS, etc docs and it seems like it should
(reg-query-sub
:cur-form-def
'[:find (pull ?e [*])
:in $
:where
[_ :designer/cur-form-id ?id]
[?e :form/id ?id]
])
There are two problems in Reagent land I keep running into: I forget to update Form-2 component arguments, and I can't get posh to re-render things when I expect to. I want to display the entire the posh db at the bottom of my page so see what's going on. I can never remember when I should deref conn or not. Why doesn't
[:code (pr-str @conn)] inside my root component re-render on every db change?
But wait a little bit. Maybe somebody else has a better idea
https://github.com/bamarco/onyx-sim/blob/master/src/cljs/onyx/sim/core.cljs using make-reaction like i do in
debug-conn here will work. Haven’t really stress tested it though might just be getting lucky. If you want to be more efficient you could rig up a listen! on the conn.
@orolle Not at present. I did some preliminary work trying to get it working, but couldn't quite sort it out. In theory it should be possible, as long as you're not putting functions or anything weird in your db. We are looking at the possibility of putting this in datsync fwiw.
Is the remaining issue that it won't garbage collect properly/automatically?
I fixed a small bug that was hiding the big one from me.
It may only be a problem with nil starting values. haven't tested yet because all my code in onyx-sim is re-com based and not rum compatible
I also tried using
build-defc from rum, but couldn't get that to work either.
Anybody know the right fn call for array? mpdairy/posh#30
Okay rum support pr should be good to go now
Is there a way to do a
Mapping over ids with
pull-all in posh? I'm trying to write a pull-all version of this: https://github.com/denistakeda/re-posh/blob/master/src/re_posh/subs.cljc#L16Mapping over ids with
p/pull gives errors. I suspect because it returns a reaction (which I don't really understand yet).
@bmaddy try using
deref after each individual pull (add it to your mapping function). This will give the value for the reaction. You may need to wrap the whole thing in a reagent.core/make-reaction function if re-posh isn't doing that automatically where you are calling the derefs.
okay! So, I'm starting out with dat[ascript|omic] for the first time via re-posh and it's terrifying! I don't know how doing things works :sweat_smile: :
okay, so I have the following value in my app-db:
@re-frame.db/app-db
=> [{:db/id -1, :app/type :type/account, :account/balance 800}]and I made a subscription like so:
(rp/reg-sub
:account-balance-id
(fn [_ _]
{:type :query
:query '[:find ?id .
:where [?id :app/type :type/account]]}))
and, firstly, it seems to be getting nil. secondly, I have no idea what the dot in
:find ?id . is for. I just copied it from the todomvc
I just don't understand enough about the workflow to debug and troubleshoot. :/
Hello Posh folks! Apologies if this topic is ongoing somewhere else, but I wanted to check and see if anyone has any progress on the combining client queries into a "scoped" datomic view? as outlined in this thread: mpdairy/posh#3 I'm curious if anyone has attempted to analyze the query data to produce a set of datoms suitable for bootstrapping the datascript client :fishing_pole_and_fish:
@Lokeh I wrote a rum plugin. There were a few bugs with it. I’ve fixed most of them, but haven’t had time to test them to make sure the fixes didn’t introduce new problems. I was also working on a refactor to make the plugin process more robust (the combination of libraries is going to become burdonsome without a more generic way to bind libraries) but I think my solution was too complex so I have abandoned it for now (I think the latest version of spec will address some of these issues)
