What is promptly?

The 'promptly' npm package is a simple utility for prompting user input in Node.js applications. It provides a straightforward way to ask for user input from the command line, with support for validation, default values, and hidden input for sensitive information.

What are promptly's main functionalities?

Basic Prompt

This feature allows you to prompt the user for input and then use that input in your application. The example code asks the user for their name and then greets them.

const promptly = require('promptly');

(async () => {
  const name = await promptly.prompt('Enter your name: ');
  console.log(`Hello, ${name}!`);
})();

Prompt with Default Value

This feature allows you to provide a default value for the prompt. If the user does not enter anything, the default value will be used. The example code sets 'Anonymous' as the default name.

const promptly = require('promptly');

(async () => {
  const name = await promptly.prompt('Enter your name: ', { default: 'Anonymous' });
  console.log(`Hello, ${name}!`);
})();

Hidden Input

This feature allows you to prompt the user for input without displaying what they type on the screen. This is useful for sensitive information like passwords. The example code asks for a password and hides the input.

const promptly = require('promptly');

(async () => {
  const password = await promptly.prompt('Enter your password: ', { silent: true });
  console.log('Password received.');
})();

Input Validation

This feature allows you to validate the user's input before accepting it. The example code validates that the input is a positive integer representing the user's age.

const promptly = require('promptly');

(async () => {
  const age = await promptly.prompt('Enter your age: ', {
    validator: (value) => {
      const age = parseInt(value, 10);
      if (isNaN(age) || age <= 0) {
        throw new Error('Invalid age');
      }
      return age;
    }
  });
  console.log(`You are ${age} years old.`);
})();
