Hello! I am trying to use the react-bootstrap-table2 ’Export CSV’ functionality and struggling with the dependencies syntax - specifically, how to require ToolkitProvider, CSVExport, and ExportCSVButton. Any tips? import ToolkitProvider, { CSVExport } from 'react-bootstrap-table2-toolkit'; const { ExportCSVButton } = CSVExport;

I'm trying to work on a react native app on an android device via USB but having a lot of trouble. I've disabled fast refresh and don't see an option for live reload or hot code reload in the debug menu. I'm on the latest shadow-cljs release (2.10.12) The app is able to load and make requests to my laptop. But whenever I update some code the app crashes instead of refreshing. If I try connecting to the app's repl I get this (using intelliJ)

Connecting to remote nREPL server...
Clojure 1.10.1
(shadow/repl :pos-bare)
To quit, type: :cljs/quit
=> [:selected :pos-bare]
1
The previously used runtime disappeared. Will attempt to pick a new one when available but your state might be gone.

#17 ready!
#18 ready!
#19 ready!
#21 ready!

just verified, repl connecting to an emulator works fine it's just the device that's broken

also verified i can make requests from the device to the server, but for some reason the runtimes still get dropped

(js/setInterval #(async/go
                   (let [response (async/<! (http/get ""))]
                     (log/spy :warn response)))
  1000)

I also followed the instructions here, with the --verbose option i see the ip address is correct and in react-native log-android I don's see anything informative about why the runtime is getting dropped. Just the following

[20:23:16] I | ReactNativeJS ▶︎ #8 ready!
[20:23:39] I | ReactNativeJS ▶︎ #9 ready!
[20:24:05] I | ReactNativeJS ▶︎ #10 ready!
[20:24:28] I | ReactNativeJS ▶︎ #11 ready!
[20:24:52] I | ReactNativeJS ▶︎ #12 ready!

@currentoor that looks odd but the timing appears to be the ping/pong timeout

if the runtime doesn't respond to pings for about ~20sec it will be kicked by the relay

the relay is sending a ping every 5sec when idle and the runtime is supposed to respond

not sure why it wouldn't?

but I also never tested this on an actual device before

you can try setting :log {:level :debug} in shadow-cljs.edn but that will likely just confirm that it is indeed kicking because of ping timeout

not why the client isn't responding

o/ 'lo there I'm writing a custom target for a resource constrained environment and am trying to figure out the proper compiler options to enable dead code elimination, but disable renaming and whitespace removal. So the code remains readable, but dead code is removed.

I want this in devel mode. the problem is a basic hello world script is 1.5MB.

I suspect if I could get a hold of the underlying CompilerOptions object, I could call setRemoveDeadCode(true) on it when using optimizations :none

@ramblurr this isn't going to work for development code

:optmizations :none literally means "do not call the closure compiler at all"

what are you doing exactly? I mean for which environment is this?

Ah 😕 I didn't know that.

I'm writing a target for the game http://screeps.com

The code players right is ES6, but not in a DOM nor a node-like environment. I started with the graaljs target, and customized it. However there is a 2MB code limit on player code, and just cljs+goog is 1.5MB.

Hm, maybe i can filter out the unneeded goog modules in the flush step.

hmm does it support ESM?

do you have a JS example?

ah looks like commonjs. why not :node-library?

No ESM support unfortunately. It supports a limited require that has no support for folders.

this might not be node but that doesn't really matter

use :node-library and shadow-cljs release while shadow-cljs server is running

that will make everything small enough so size isn't an issue

or maybe :npm-module works too

compile might work for that one but you'll be approaching the size limits pretty fast

Yea, I got it working at first with :node-library (or was it node script? don't remember), in dev and release modes. But in this game you'll need to react on the fly to things happening in the world, and it is very useful to see the un-minified code. You'll often react to some event in game by patching the deployed code, then later bringing those changes back into your codebase.

:release / advanced optimizations makes that all but impossible.

hmm does it support websockets? might be fun to get in there and use the REPL to tune stuff 😛

you could try :simple with :pretty-print

but that'll also be close to the max size

the official game doesn't, but, since its open source, i'm working on a patch to the server to allow WS. That would be useful for testing outside the main official server.

getting a repl is one of my goals, it would be tons of fun (even if not on the main server)

:simple with just cljs.core is about 1mb. not sure how much code the game code ends up being but that might be fine?

:target :esm would be by far the best option for this .. shame they don't support it 😛

Oooh, yea cljs.core is the heavy item here, not the extra goog libraries

what is the proper way of creating a DevTools page when developing a Chrome extension?

@eallik maybe https://clojureverse.org/t/generating-es-modules-browser-deno/6116?

devtools_page in the manifest needs to point to an .html page, so I generate an ESM module and then manually include it in that .html page?

yeah. you can also just use a :browser build though

great, will try out both

@thheller Just tried the shadow’s Inspect feature — works great! Thank you :star-struck:

@thheller do you know of any writeups regarding how the cljs repl works?

Hello, how do I include dependencies for specific builds? e.g. I want to add re-frisk to my :dev build, but not in my :prod build?

@thheller not sure how to debug this, but I think there may be some kind of race-condition bug. With the newest  `malli.registry/type` code (that checks for a setting via closure-defines), once in a while (but only after a shadow-server restart) I see the `{:type "default"}` exception (i.e. a missing closure-defines option), but it Just Works™ if I "force compile" the build once in the shadow UI.

Hello, I have some trouble with the shadow-cljs modules: I have a google closure error saying 1. Do you know what this would be?

oh I think I got it, there is an error in cljs.spec.alpha when calling gen...

@kevin.van.rooijen classpath doesn't matter just always include it. and then add re-frisk via :preloads.

The JS doesn't get included if I don't :require it manually?

correct

Makes sense, thanks!

@ramblurr only https://shadow-cljs.github.io/docs/UsersGuide.html#repl-troubleshooting

> The goog: prefix currently only works for ES6 file. require("goog:cljs.core") does not work. There's no way to call cljs from js then when ESM isn't available?

:npm-module or :node-library

re the repl docs: that is a nice high level explanation. To implement a repl for screeps, I'd need to be able to implement #3 Transfer Out and #6 Transfer Back using something besides web sockets... vanilla http requests

It is unlikely that you need to implement that since there already is an impl for websockets

but I don't know enough about the screeps runtime and what it can do

There are no websockets. from inside the game i can read/write json to a memory location, from outside the game I can read/write to that memory location using an HTTP GET/POST.

I'll dive into the impl and check it out.

thats the node client impl

https://github.com/thheller/shadow-cljs/blob/db55036fb6988fb3146fb91a9554da25932209c6/src/main/shadow/cljs/devtools/client/browser.cljs

browser has a bunch more stuff but the core impl is the same

https://github.com/thheller/shadow-cljs/blob/master/doc/remote.md this might also be relevant

thats how it all works together
