Description

Changes related to this issue: #299 cause integrity check errors provided below. These errors happen once you attempt to use social media icons for instance:

Failed to find a valid digest in the 'integrity' attribute for resource '<website>/fontawesome/css/solid.min.6ee9fbc38b1b14c99d05fdc597d9af749968eaf84e43050a6d059cad81a60bcc.css' with computed SHA-256 integrity 'TrP1Z4d6t0hI+yNEp2g3zJtsxCrjYjY0jF9GcV/frWc='. The resource has been blocked.

Failed to find a valid digest in the 'integrity' attribute for resource '<website>/fontawesome/css/fontawesome.min.3eab8ef80d1761270f30323d1bd5d9d10a8f6a7610dbe233adba89094ed48fbd.css' with computed SHA-256 integrity 'E3K98f0smgriSX7SBZWMREv8HAM28mqcd9hcqPvnzlg='. The resource has been blocked.

The reason for these errors is that the initial changeset added 3 *.min.css files:

• brands.min.css
• fontawesome.min.css
• solid.min.css

...but in the wrong format. Instead of being a one-liner, these files were indented and pretty-formatted which is different from the original source: https://cdnjs.com/libraries/font-awesome/6.0.0 and therefore gets a different checksum generated.
The fix for this is to add properly compressed .min.css files. Files are taken from the original CDN, version 6.0.0 which is currently the one being used by Anatole theme.
The fix has been tested both on Desktop and mobile version of the theme.

@guidemetothemoon Thanks for your PR. I totally agree that the files should be minified if they carry "min" in their name.

The one thing that baffles me a bit is why you got the integrity error as Hugo will calculate the hash over the files no matter if the content is pretty printed or minified. I think if this had been a global problem, it would have came up quite quickly. Nevertheless I will go ahead and merge the PR. Thanks again.

@guidemetothemoon LGTM. Thanks for the PR.

Thanks for the review!
I agree, I did some research and was surprised that no issues from others were raised for the same. I first thought that the issue may have been related to the line endings but after some tweaking back and forth I ended up with current resolution. Could it be that if the content is not minified, then the checksum is still different because the content kind of changes in terms of size? That's what I saw in this case at least. Or maybe this has something to do with how template is set up? I'm using the traditional set up as a Git submodule. But anyway, happy to help!
And thanks for this theme - I'm actively using it for my tech blog and absolutely love it! :)
