How does commander.parseArgs work?

commander.parseArgs is a function provided by the Commander.js library that can be used to parse command-line arguments. When called, it reads the command-line arguments and processes them according to the configuration set up by the Commander.js library. The function then returns an object containing the parsed options and arguments.

The commander.parseArgs function accepts two optional parameters:

args (default: process.argv.slice(2)) - An array of arguments to parse, typically obtained from process.argv.slice(2).
parseOptions (default: true) - A boolean indicating whether to parse options.

When parseOptions is true, the commander.parseArgs function will parse the command-line arguments and extract options and their corresponding values based on the configuration set up using the Commander.js API. It will then return an object containing the parsed options and their values.

If parseOptions is set to false, the commander.parseArgs function will only extract non-option arguments and return them as an array.

Overall, commander.parseArgs is a powerful function that can be used to quickly and easily parse command-line arguments in a Node.js application. It is especially useful when used in conjunction with the other features of the Commander.js library.

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

program
  .option("-n, --name ", "The name of the user")
  .option("-a, --age ", "The age of the user")
  .parse(process.argv);

const { name, age } = program.parseArgs();

console.log(`Name: ${name}`);
console.log(`Age: ${age}`);

In this example, we first set up a Commander.js program object using the .option() method to define two options: --name and --age. We then call the .parse() method to parse the command-line arguments. Next, we call program.parseArgs() to extract the parsed options and their values from the command-line arguments. We store the values in name and age, respectively. Finally, we log the values of name and age to the console. If we run the script with the following command-line arguments: css Copy code
