Notifications support is provided via long polling.
Long polling means that once established, a connection will stay open until required data is available.
Once a message you are waiting appears, the server will send a redirect to the new content.
Client support is somewhat lacking (kristall default timeout is 5s), while this works fine in Emacs elpher (the page with the new message will load as soon as the message is sent).
A simple way to watch for messages can be done with OpenSSL s_client:
echo '//nixo.xyz/notify' | openssl s_client -connect nixo.xyz:1965 -ign_eof -crlf && notify-send "DNA" "New message received!"
As shown in the previous example, the endpoint is
Without parameters, this endpoint will watch for any new message.
You can filter it by using query parameters. 4 options are currently available:
Only direct replies to your messages (you are identified with the client certificate)
Messages in reply to this specific id.
Is the same as watching the MSD_ID corresponding to the main board message.
Notify about messages sent by this specific user name.
