For the egui-corcles project, incorrect MIME is returned for *.js files failing the whole Pages flow

Expected:

Content-Type: application/javascript

Actual:

get https://demo.pages.djmil.dev/egui-circles/egui-circles-4f8030f072449e22.js
Content-Type: text/plain; charset=utf-8

Caddyserver github issue:

Go pulls mime type mappings from the operating system (mailcap file locations), so if it's not correctly set on your system, then it won't serve the right content type

Check file mime type:

file --mime-type -b sw.js
> text/plain

Possible sollutions

Add custom mime type (ubuntu)
Modify Caddyfile with header /*.js Content-Type text/javascript

Updating Alpine's MIME type internals seems to be hard and not easily automated (for the docker images). Thus it looks that i have to focus on editing Caddyfile to enable remapping of Content type for *.js files.

Caddy 2 does not sniff MIME by default, either, for security reasons; if a Content-Type is missing you may need to set the header yourself using the header directive. (c)

Caddyfile structure

Caddyfile Blocks

When there is only one site block, the curly braces (and indentation) are optional (c)

Going to try to modify the default Caddyfile with

:3003 {       # site
	gitea {   # plugin
		token  {$GITEA_ACCESS_TOKEN} # Settings > Applications > Generate Token
		server {$GITEA_HOST}   # https://yourgitea.yourdomain.com
		domain {$PAGES_DOMAIN} #             pages.yourdomain.com
	}
	
	@js {        # matcher definition
		path *.js
	}

	header @js { # directive
		Content-Type text/javascript
	}
}
