Function getAvailablePort

getAvailablePort(options?): number
Returns an available network port.

[!IMPORTANT] In most cases, this function is not needed. Do not use it for trivial uses such as when using Deno.serve or Deno.listen directly. Instead, set the port option to 0 to automatically use an available port, then get the assigned port from the function's return object (see "Recommended Usage" example).
Parameters
- Optionaloptions: GetAvailablePortOptions
  Options for getting an available port.
Returns number
An available network port.
