pub const DEFAULT_AT: &str = "127.0.0.1:8787";Expand description
Where a city listens when nobody says otherwise: the loopback interface, so a city started by a double-click is reachable from the browser on that machine and from nowhere else.
up, serve, the first screen, and every command that talks to a
served city read this one value, and the installer script and README
quote it, so the address a person is told is the address that binds.
