👋 I have this problem working with npm library called js-waku https://stackoverflow.com/questions/66309813/the-required-js-dependency-readable-stream-writable-js-is-not-available-it-wa

I tried forcing version 2.0.2 of readable-stream as suggested in SO solution but get another error after that transpilation of BigInt is not supported

Thank you for any help unraveling this mystery

try :compiler-options {:output-feature-set :es2018} in your build config. maybe :es2019 or :es2020. not sure which language level bigints were

Cool thank you that make sense I will give it a go

Seems it was in :es2020 but still no dice 😞 I get failed to convert sources on a whole bunch of libraries

I cannot guess the errors you get sorry

:ex-next-in is the highest level possible, maybe that works

ooohh that might js-waku is written in typeScript with compiler option esnext

that isn't relevant, js config options don't apply to closure compiler options

still that did not work same failed to convert sources error

don't shorten errors ... you cut out the reason why it failed

It was too big to fit.. so attaching file of log

RuntimeException: INTERNAL COMPILER ERROR.
Please report this problem.

  Parent(IF): node_modules/bcrypto/lib/native/bn.js:3605:2

this is a closure-compiler error, it appears that it doesn't support the code

you can try using webpack with this method https://code.thheller.com/blog/shadow-cljs/2020/05/08/how-about-webpack-now.html#option-2-js-provider-external

Thank you for the prompt response and incredible patience 🙏 I will give webpack a go

are you sure this code is supposed to be supported in the browser? I see a bunch of node specific stuff so it looks like a node thing to me?

I am pretty sure it is supposed to be supported in the browser https://www.npmjs.com/package/js-waku

hmm yeah seems rather cutting edge

yeah.. freshly released.. hardly battle tested.. I'm also communicating with the dev.. so let's see I'm going to try everything I can
