Clojurians Log v2

@andrei.stan I'm not sure if you fixed your problem or not, but you can always use re-frame-template to obtain a working re-com app

i have upgraded, build is ok, it still doesn't work. the build is ok, but i receive errors in browser console:

Hello fellow clojurians... I've been working on an electron + re-frame + shadow-cljs app for the past few weeks and I've been running into an issue trying include an npm package called electron-store. If I understand the error logs correctly, it seems shadow-cljs doesn't like the javascript spread syntax that the electron-store library uses in a few places. Any idea why this is the case? All of my packages are fully up to date (at least as I'm aware) and I'm running on Node.js v14.13.0. Any thoughts around root cause would be much appreciated and let me know if there's more information I can provide to help clarify. Thanks! JS Error:

@jarredlhumphrey this is an internal electron/node error. it has trouble loading that file. not shadow-cljs.

just run node and then require("electron-store"). that should give you the same error.

maybe some electron/node setting configures which language version it accepts or so?

looks like you have something undefined that shouldn't be [thing {:foo "bar"}] where thing is undefined or so

Hey! I'm having trouble using Datascript under Shadow-CLJS and advanced compilation. Before I write up a minimal example, has anyone else had this problem? I'm using Shadow-CLJS 2.11.5 and Datascript 1.0.1.

you need to include the externs for some reason. no clue why.

Ah, that's a bit random. Thanks!

That fixed it. Thanks a lot, @thheller 🙏

@thheller hmm when I do this from Node I don't receive any errors. Similarly, when I try to run an example vm.runInThisContext call from Node with a spread operator (as thats the command in shadow-cljs thats choking) I dont have any issues. So it seems to be just from the context of shadow-cljs that its barfing. I'm going to dig into electron a bit and see if it does anything special to node or the vm that might effect this, but otherwise still a little stumped. Anyhow, thanks for your help here I really appreciate it.

no clue. shadow.js.shim.module$electron_store.js is literally only doing require("electron-store") and the failure is in that file. shadow-cljs has not processed that file in any way and it is just up to electron fulfilling that require.

Ok thanks for the clarification. Appreciate it!
