How does commander.port work?

I'm sorry, but there is no commander.port method in the Commander.js library. Commander.js is a framework for building command-line interfaces in Node.js and provides methods for defining command-line options, arguments, and commands, but it does not have a port method. If you could provide more information or context, I might be able to help you better.

  .option('--busywait [num]', 'Number of seconds to busy wait for a command (for pretending to be a busy server)', STK.util.cmd.parseInt)
  .parse(process.argv);

var port = cmd.port;
var sio = SocketIO(port, {
  pingTimeout: cmd.ping_timeout*1000
});

const { Command } = require("commander");

const program = new Command();

program.option("-p, --port ", "Specify the server port", 3000).parse();

console.log(`Server running on port ${program.port}`);

In this example, the option method is used to define a --port option that accepts a value, and also has a short alias -p. The value passed to option specifies the help message to be displayed when the user runs the --help command, and the default value to be used if the user doesn't specify a value. The parse method is called to parse the command-line arguments and assign the resulting values to the program object. Finally, the program.port property is used to access the value of the --port option.

这时,该选项就以`program.port`的形式被保存,于是手动修改一下:

```
// 39行
if (program.port) {
        appConfig.port = program.port;
}
```

这是处理Node.js应用全局配置的一种常用且简单的方式,值得学习。
