I’m trying to use https://www.npmjs.com/package/@aws-sdk/client-cognito-identity-provider from a :browser target. When I require what I need like this

(ns main
  (:require
   ["@aws-sdk/client-cognito-identity-provider" :refer [CognitoIdentityProviderClient]]))

#object[TypeError TypeError: $jscomp.inherits is not a function]

The ES6+ import example from that NPM page looks like this

import { CognitoIdentityProviderClient, AddCustomAttributesCommand } from "@aws-sdk/client-cognito-identity-provider";

Upgrading shadow to the latest seemed to resolve the issue. Weird as a colleague on an older version didn’t experience it.

@stuartrexking that is a known issue that I have not been able to reproduce and track down unfortunately

going a bit crazy with a new project and tools.deps integration. Certain I had this working before. I have a deps.edn like:

{:paths ["src"]
 :deps {}
 :aliases 
 {:dev
  {:extra-deps {thheller/shadow-cljs {:mvn/version "2.9.2"}}}
   :main-opts ["-m" "shadow.cljs.devtools.cli"]}}

{:deps true
 :builds {:app
          {:target :node-script
           :output-to "target/main.js"
           :output-dir "target"
           :exports {:handler platform.core/handler}}}}

Execution error (FileNotFoundException) at java.io.FileInputStream/open0 (FileInputStream.java:-2).
watch (No such file or directory)

oh fuck it was wrongly nested braces in the deps.edn. The closing brace on extra-deps line meant that :main-opts was added as an alias and so ignored. Thanks for the help 😅

hello, I'm having an issue to use the shadow ns in a project here, it says the namespace isn't defined, but others like shadow.cljs.devtools.server.nrepl are there, any ideas what could be wrong?

> npm install bulma Can I make shadow serve css out of that node_module during dev watch & whatnot?

no, css is not supported

I mean sure you can make it serve static files just fine but it won't process css in any way

Shadow sometimes starts throwing when evaling cljs, forcing me to restart it. It happens after a while, somewhat randomly. I don't have any cljs/user.cljs file since I know that Shadow treats it specially. I guess this must be because something is missing in my config:

@adam678 which version is this? I fixed this not too long ago

I upgraded some time ago to 2.11.4 but it didn't go away

I'll upgrade again then

I think I fixed it in 2.11.10

just try 2.11.15

Failed to inspect file
  /home/clyfe/dev/riviera/node_modules/monaco-editor/esm/vs/editor/standalone/browser/standalone-tokens.css

it was required from
  /home/clyfe/dev/riviera/node_modules/monaco-editor/esm/vs/editor/standalone/browser/standaloneEditor.js

like I said earlier. css is not supported.

Hello, I would be grateful for some help deploying an app to Heroku. I built a shadow-cljs app using: https://github.com/filipesilva/create-cljs-app Worked fine locally. But then I tried deploying it to Heroku and I got this error: "Executable 'java' not found on system path." I even tried deploying the default app provided from both my computer and Cloud9 IDE and I got the same error. Any thoughts on how to get this work? Thanks!

sorry don't know anything about heroku but java will be required to build things

dunno why you have to build on heroku though. you could just build locally and deploy the static files

Right, I built locally. I think what you're saying is that I don't have to deploy the whole repo. Is that right?

Can someone please recommend a service to deploy a shadow-cljs app? I tried Heroku and it didn't work. Can you tell me one that does?

@markdmcq That repo you linked to outputs a static single page app. Any static hosting site should be able to host it once you have built it.

I do build it. But then I get that java missing error. I think there's a problem with Heroku.

You need java and npm to build that site though. You would normally do that on your machine before deploying (copying) the output files (html, js, css) to a static site somewhere.

Yes, it gives me a public folder with javascript and css. I haven't found a way to run it though.

Once you have the static files you just need to put them somewhere that can serve them, like a webserver or CDN or a static site hosting. They won’t be run like I think you are suggesting.
