إعداد الرمز المفضّل: " ليعمل بشكل صحيح عبر CDN يجب أن يكون png"

The config for favicon says:

To work correctly over a CDN it must be a png

What does this mean, which CDNs, and why wouldn’t an svg work?

Any CDNs (content delivery networks) you may have configured for hosting files when setting up your site, for example: Configure an S3 compatible object storage provider for uploads

If you aren’t using a CDN like this, then you can likely disregard the message.

The short answer is that Discourse expects a PNG on the backend.

The long answer seems to be related to this comment in the related code, though I’m not familiar with these technical specifics:

github.com

discourse/discourse/blob/main/app/controllers/static_controller.rb#L134-144


      
              rescue URI::Error
                # Do nothing if the URI is invalid
              end
            end
          
            redirect_to destination
          end
          
          FAVICON ||= -"favicon"
          
          # We need to be able to draw our favicon on a canvas, this happens when you enable the feature
          # that draws the notification count on top of favicon (per user default off)
          #
          # With s3 the original upload is going to be stored at s3, we don't have a local copy of the favicon.
          # To allow canvas to work with s3 we are going to need to add special CORS headers and use
          # a special crossorigin hint on the original, this is not easily workable.
          #
          # Forcing all consumers to set magic CORS headers on a CDN is also not workable for us.
          #
          # So we cache the favicon in redis and serve it out real quick with
          # a huge expiry, we also cache these assets in nginx so it is bypassed if needed
