App extension code splitting

Shopify Partner

When I tried to build my subscription app extension, I got this error.

Error: Error compiling: asset size limit: The following asset(s) exceed the recommended size limit (244 KiB).
This can impact web performance.
  main.js (291 KiB),entrypoint size limit: The following entrypoint(s) combined asset size exceeds the recommended limit (244 KiB). This can impact web performance.
  main (291 KiB)


So I changed my code to use React.lazy and dynamic import, but now I get the error below.

TypeError: importScripts is not a function
    at http://localhost:39351/assets/extension.js?reload=0:817:14
    at async Promise.all (index 0)

I know this is a niche issue but I would appreciate it if someone could provide information about how to deal with this.

And please tell me if I need to provide more information. Thanks.

Hey, there seems to be a problem with the argo extension. The same thing is going on for me too. I am able to compile but unable to push the code to shopify.

Hi, @d_tehrani.


Have you ever figured out the solution to this problem of yours? I'm experiencing it now. Thanks!
