Hosting files instead of using cdn

[JerryWho]

In Germany using Google fonts is not allowed anymore without consent of the user because of GDPR. (see German news at https://www.golem.de/news/landgericht-muenchen-einbindung-von-google-fonts-ist-rechtswidrig-2202-162826.html)
It is expected that any other use of cdns will be a problem, too.

So it would be great that we could switch to own hosting of the files currently hosted on cdns.

You can include local JS files using e.g. pkgdown/assets/local.js and refer to them using:

template:
  includes:
    in_header:
      <script src="local.js"></script>

This is also related to #1968

Two examples of templates that do not use Google fonts

• rotemplate (as inspiration, the template is not for general use)

  • font mentioned as a bslib parameter https://github.com/ropensci-org/rotemplate/blob/01e8ebccdafcb9f546fde2a7fbcf6d9ed3405284/inst/pkgdown/_pkgdown.yml#L22
  • extra.scss has rules about the font (that is served from our main website) https://github.com/ropensci-org/rotemplate/blob/01e8ebccdafcb9f546fde2a7fbcf6d9ed3405284/inst/pkgdown/extra.scss#L189-L200

• bcdata

  • config file https://github.com/bcgov/bcdata/blob/c6f53c533a62cda1f4c0d99475325689c78a7128/_pkgdown.yml#L9
  • CSS rules https://github.com/bcgov/bcdata/blob/master/pkgdown/extra.css
  • fonts files in the package itself https://github.com/bcgov/bcdata/tree/master/pkgdown/assets/bc_sans

For other CDN, you might want to look into custom head templates https://pkgdown.r-lib.org/articles/customise.html#additional-html-and-files

Adding custom js-files won’t solve the problem. As I understand the docs the additional code is added. So cdn-files are still there.
Creating a custom template without any cdn files would solve the problem. It would be nice if this template is part of pkgdown and can be used by just setting the right switch on creating the site.

@JerryWho precisely what fonts are you talking about? Perhaps I'm missing something, but I don't see any sign that (e.g.) https://pkgdown.r-lib.org is downloading fonts from google. And in font_google(), localdefaults toTRUE` which I think implies that in most cases any external google fonts will be downloaded and served from your site.

[JerryWho]

@hadley Google Fonts were just the trigger for a verdict in Germany. But it is expected that any files loaded from cdns need consent by the user.

So I'm looking for a solution to host all files (such as js, css etc) locally and not being hosted by a cdn.

Is #2099 relevant?

Is #2099 relevant?
Yes, you are right. That’s exactly what I’m looking for.
