How does yargs.options work?

yargs.options() is a method that allows you to define the options that your command-line application can accept, specifying their names, types, default values, descriptions, and other properties. When you run your application, these options can be passed in as command-line arguments, and yargs will parse and validate them for you.

const yargs = require("yargs");

// Define options for the command
const options = {
  name: {
    describe: "Name of the user",
    demandOption: true,
    type: "string",
  },
  age: {
    describe: "Age of the user",
    demandOption: true,
    type: "number",
  },
  email: {
    describe: "Email address of the user",
    demandOption: false,
    type: "string",
  },
};

// Register the options with yargs
yargs.options(options);

// Parse command-line arguments
const argv = yargs.argv;

// Access the values passed in via the command line
const { name, age, email } = argv;

// Use the values as needed
console.log(
  `User ${name} is ${age} years old and their email is ${email || "unknown"}`
);

In this example, yargs.options is used to define the options for a command-line utility. The options are specified as an object where the keys are the option names and the values are objects that define the option properties such as describe, demandOption, and type. The yargs.options method is then used to register the options with yargs. Once the options are registered, they can be accessed via the argv object returned by yargs.argv.
