ssentr

Send SSE when files change.

Setup:

$ cat Caddyfile
{
	http_port 8085
}
:8085 {
	route /reload {
		header Access-Control-Allow-Origin *
		header Access-Control-Request-Method GET
		reloader
	}
}

Usage:

find -iname '*.html' | ssentr run

Add the following hyperscript to your project

<script type="text/hyperscript">
eventsource Reloader from http://localhost:8085/reload
    on message
        call location.reload()
    end
    on error
        log "error with connecting to reload SSE"
    end
    on close
        log "closing reload SSE"
    end
end
</script>

When any of the files change, a message will be sent to any connection to http://localhost:8085/reloader
