Deno.ServeTcpOptions - Deno documentation
interface Deno.ServeTcpOptions
Options that can be passed to `Deno.serve` to create a server listening on a TCP port.

Properties

optional
transport: "tcp"
The transport to use.
optional
port: number = 8000
The port to listen on. Set to `0` to listen on any available port.
optional
hostname: string = "0.0.0.0"
A literal IP address or host name that can be resolved to an IP address. __Note about `0.0.0.0`__ While listening `0.0.0.0` works on all platforms, the browsers on Windows don't work with the address `0.0.0.0`. You should show the message like `server running on localhost:8080` instead of `server running on 0.0.0.0:8080` if your program supports Windows.
optional
reusePort: boolean
Sets `SO_REUSEPORT` on POSIX systems.
