Hello @psytron,

Please check out this example regarding web workers' usage: https://github.com/ccxt/ccxt/tree/master/examples/html/webworker

Let me know if that does not help.

[psytron]

Thanks @carlosmiei. That example is using old style "importScripts" and requires type:'classic'

New esm style import using Worker( {type:module } ) enable intermixing and importing new es6 modules.

@psytron we are working on adding esm support to ccxt - see #12619, we plan to complete it later this month

[psytron]

In the meantime are solutions like https://esm.sh/ and https://esbuild.github.io/ recommended ?

[psytron]

Is this recommended in the meantime ? https://github.com/carlosmiei/ccxt

Since the migration of ccxt.pro into ccxt, the new browser versions (1.93.100 and higher) won't work in a webworker context anymore.

[psytron]

Any updated thoughts on this? Enabling smooth fast UI and responsive apps would benefit tremendously from ability to offload heavy server communications like ccxt into an independent process ( web worker )

[dkraemerwork]

Yes, its working again since the first of november actually.

closing since this has been fixed
