Fixes #6

According to this article and others I have read you need to remove the "type": "module" line for it to work. I tried with those changes locally at that made it work for me.

Hi @mariusGundersen, thanks a lot for your involvement!

I see, having the main.cjs file as main is the "CJS first" approach. I was trying an "ESM first" approach, but I can see that's not gonna work. I didn't realize even Vite.js recommends CJS first.

But they also recommend keeping "type": "module" and I'm actually getting build errors if I remove it. I've published react-call@next again with your suggested approach but keeping type module. Could you check if that works for you? Thanks for your patience.

Yes, now it works! It seems like the problem was "default": "...", it works much better with "import": "...", probably because the default is controlled by "type": "module".

Thank you for taking the time to fix this for me 🥳

Glad to hear that! I've also been reading a bit more about it just to make sure. According to Vite.js CJS troubleshooting what we're doing matches the "Configure ESM as default, opt-in to CJS if needed" approach, which I think is great to remain in the modern direction!

I'll check everything is still working properly for ESM consumers and we'll get this published on v1.2.0.

@mariusGundersen thanks for contributing!
