It might be desirable to only expose the share functionality of Trilium to the Internet, and keep the application accessible only within a local network or via VPN.

To do so, a reverse proxy is required.

Caddy

http://domain.com {
  reverse_proxy /share http://localhost:8080/share
}

This is for newer versions where the share functionality is isolated, for older versions it's required to also include /assets.^[1]
