How does commander.password work?

commander.password is a method in the Commander.js library that prompts the user to enter a password in the command line interface.

When commander.password is called, it uses the readline module to prompt the user to enter a password. The entered password is then returned as a Promise.

The password input is not displayed on the screen as the user types, in order to provide a basic level of security.

Here is an example of using commander.password to prompt the user to enter a password:

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

const program = new Command();

program
  .command("login")
  .description("Log in to the application")
  .action(async () => {
    const password = await program.password("Enter your password: ");
    console.log("Password entered:", password);
  });

program.parse(process.argv);

In this example, we use commander.password to prompt the user to enter a password when the "login" command is executed. We pass a prompt string as an argument to commander.password to tell the user what to enter.

The entered password is returned as a Promise, which we await in the action function. We then log the entered password to the console.

Note that commander.password is a convenience method provided by the Commander.js library, and does not provide any additional security beyond hiding the entered password on the command line. For more secure password handling, you may want to use a third-party library or roll your own solution.
