[@snowpack/app-template-11ty] - HMR issue eleventy templates

[Lukjuh]

Hi there,

I don't know if this is a specific platform problem, but I have the following problem with the HRM.

I use the @snowpack/app-template-11ty and it works fine except that HRM is not working for the about.md the page gets refreshed and even in the _ouput folder the about/index.html updates with the given change. Only i don't see the change on the page it self. Only if i run npm start again is see the changes.

Added h1

Not seeing the change in the browser

Sometimes i get this error:

On my linux machine everything is working fine.

Hm @Lukjuh thanks for all the info! I admit I’m testing this on a Mac, not a Windows, but we are using this on a few of our own websites and the HMR seems to work fine. I’m not 100% sure, but based on those error messages those seem to be coming from 11ty, not Snowpack. Have you been able to use 11ty successfully outside of Snowpack?
