}The module works with different frameworks of Deno. You can check an example with OAK in the examples/ folder. It is inspired by get-port, find-free-port or other related packages for nodejs.
getPort(port?: number, options?: { log?: boolean }): numberIf port was specified it returns that port, if it was not, it returns a random port assigned from the Operating System.
Optional parameters:
{ port?: number }{ log?: boolean }
Example usage:
getPort(3000, { log: true });
getPort(3000); // by default log is falseportSelection(ports: Array<number>, options?: { log?: boolean}): numberReturns a port from the specified selection of ports in the ports array.
Required parameters:
ports: Array<numbers>
Optional parameters:
{ log?: boolean }
Example usage:
portSelection([8080, 3001], { log: true });
portSelection([3000, 3011]); // by default log is falseportRange(min_port: number, max_port: number, options?: { log?: boolean}): numberReturns a port in between min_port and max_port.
Required parameters:
min_port: numbermax_port: number
Optional parameters:
{ log?: boolean }
Example usage:
portRange(3001, 8080, { log: true });
portRange(3000, 3011); // by default log is falseThere are no race conditions when the ports are assigned.
