How does commander.opts work?

commander.opts is a method in the Commander.js library that allows for the definition of options for a command-line interface. It provides a way to specify the various options that a command can take and their configuration, such as short and long flag names, descriptions, and default values. The method also defines how the options are parsed and mapped to the command's action function.

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

program
  .option("-p, --port ", "Port number", parseInt)
  .option("-h, --host ", "Host name or IP address")
  .option("-d, --debug", "Enable debug logging")
  .parse();

console.log(program.opts());

In the example above, .option() is used to define three options: --port, --host, and --debug. The first argument is the option string and the second argument is the description. The third argument is an optional transformer function that can be used to parse or transform the option value. Finally, .parse() is called to parse the command-line arguments and .opts() returns an object containing the parsed options.
