Bundling error with 3.1.1

[KittyGiraudel]

Good morning! 👋

As per 3.1.1 (which changed bundling system to iife), Webpack bundling of classcat causes the following error:

TypeError: classcat__WEBPACK_IMPORTED_MODULE_1___default(...) is not a function

With all due respect, I suggest not changing what your library exports in a patch. 😄

You probably should roll back to 3.1.0 or publish 3.1.2 with amd bundling and offer iife in 4.0.0 or optionally in a minor along side with the existing export interface.

Hope it helps!

@hugogiraudel I don't understand. Why doesn't webpack pick up the module field from pkg.json pointing to the ES6 source?

classcat/package.json

Line 6 in 4ace17d

"module": "src/index.js",

So, what should we do / export then? Go back to UMD or is there a way to make it work like this by exporting an IIFE? 🤔

With all due respect, I suggest not changing what your library exports in a patch.

Thanks, makes sense.

As of right now, version 3.1.1 is breaking a lot of builds because of the change of export. Since it is not possible to unpublish a version, I suggest you either:

• publish 3.1.0 as 3.1.2,
• or change the type of bundling back to umd in 3.1.2.

Maybe we ask someone from Webpack to shed some light on that issue once the fix has been published. :)

I am looking at this webpack/webpack#1979, maybe it is related.

@hugogiraudel Could you share the part of your webpack config where you specify the target? I suppose it is node?

[jorgebucaran]

Anyway, here is 3.1.2 unbreaking the issue.

3.1.1 will be remembered as the rogue one.

Thanks! :)
