When receiving responses from a datomic-backed server, the db/id are large numbers such as 44143192831950917. Looks like fulcro is converting them into goog.math.Long under the hood. The problem is that when I use the bidi-based routing it does not know how to handle those goog.math.Long

No protocol method ParameterEncoding.encode-parameter defined for type object: 46157498134036548

@pvillegas12 you can convert load data with a post-mutation.

depending on what you’re doing

I’m not sure where that error is coming from

Fulcro uses transit. See the conversion table here: https://github.com/cognitect/transit-cljs

@pvillegas12 https://github.com/juxt/bidi/blob/master/src/bidi/bidi.cljc#L34 is what you need to deal with

you need to extend that protocol

@tony.kay I’m using the datomic generated ids in my fulcro UI. Those ids are used for routing, replacing the datomic payload with an initial-state one with the same data worked correctly (does not use the implicit conversion to goog.math.Long I suppose. I’ll look into extending the protocol

Any pointers for using the shadow-cljs version of the fulcro template with emacs?

It seems like I have to start both a lein nrepl connection and a shadow-cljs nrepl connection (in both clj + cljs mode) to get everything to work, is there anything more straightforward?

@fiddlerwoaroof no idea about the emacs side but you can run use the lein nrepl server and use the embedded version https://shadow-cljs.github.io/docs/UsersGuide.html#_embedded_nrepl_server https://shadow-cljs.github.io/docs/UsersGuide.html#embedded

Cool, server/start! was the piece I was missing

lein with-profile +cljs repl
user> (go)
user> (require '[shadow.cljs.devtools.api :as shadow])
user> (require '[shadow.cljs.devtools.server :as server])
user> (server/start!)
user> (shadow/watch :main)

Now I just need to figure out how to duplicate that inside cider
