via https://mathiasbynens.be/notes/touch-icons and @nhoizey

also optionally support root directory lookups for:

    apple-touch-icon-57x57-precomposed.png
    apple-touch-icon-57x57.png
    apple-touch-icon-precomposed.png
    apple-touch-icon.png

though that seems unlikely as additional HTTP requests here are not ideal

Wanting to use this project, I tested to deploy on Netlify by hand or via the quick deployment button available on the readme. Each time the generation does not work

Is there any manual configuration to do on the Netlify side? I haven't found anything like that.

Thanks

When declaring a sizes attribute with "any" rather than "1x1" the largest icon isn't returned.

The example below from https://jkc.codes/ returns the 32x32 icon rather than the SVG

<link rel="icon" href="/img/site/icon-site-16x16.png" type="image/png" sizes="16x16">
<link rel="icon" href="/img/site/icon-site-32x32.png" type="image/png" sizes="32x32">
<link rel="icon" href="/img/site/icon-site.svg" type="image/svg+xml" sizes="any">

And if you do this it returns the 16x16 icon (don't ask me why)

<link rel="icon" href="/img/site/icon-site-16x16.png" type="image/png" sizes="16x16">
<link rel="icon" href="/img/site/icon-site.svg" type="image/svg+xml" sizes="any">
<link rel="icon" href="/img/site/icon-site-32x32.png" type="image/png" sizes="32x32">
<link rel="icon" href="/img/site/icon-site.svg" type="image/svg+xml" sizes="any">

If your site uses an SVG as its favicon, the leaderboard doesn't display it. You should add support for it. Example entry in the html head: <link rel="icon" type="image/svg+xml" href="data:image/svg+xml,blah">

I think this would be a useful feature to have, so people could add the own backup images if the Indie Avatar is not found, could potentially be a local image or external

A photo of the user can also be represented via a photo class on a tag within a .vcard entry in the content of the page, as described in hcard 1.0 microformat.

The BIMI standard is specifically designed for this use case. It's a DNS text record pointing to an SVG avatar. I thought this was a really neat idea and went and added support for it. Later I realized big global corporate email clients will only show BIMI avatars that are verified with a VMC that you have to pay a yearly fee to DigiCert or Entrust for AND you need to have a registered service mark. This effectively limits the technology to big global corporations.

I would love to see this implemented in more indie applications.
