Simple library of user-input prompts

This module contains several convenience methods for interacting with the user via the command line.

Examples

Each method returns a Promise that resolves to the user's input. The prompt and whisper methods are identical, except that the latter hides the user's input by converting each character to asterisks (for passwords and such). The yn method prompts the user for a binary choice and then resolves to a boolean.

const { prompt, whisper, yn } = require('@dawaltconley/cue')

const getLogin = async () => {
    let info = {}
    info.username = await prompt('Username:')
    info.password = await whisper('Password:')
    if (await yn('Display login info?')) {
        console.log(info)
    }
}

The prompt and whisper methods can also take an object or array of prompts as their argument, which will run in the order provided and return an object or array of answers.

const getInfo = () => prompt([
    'Name:',
    'Age:',
    'Height:'
]).then(([name, age, height]) => {
    console.log(`${name} is ${age} years old and ${height} tall.`)
})

const setPassword = () => whisper({
    password: 'Password:',
    confirm: 'Confirm password:'
}).then(({ password, confirm }) => {
    if (password === confirm) {
        console.log('Passwords match.')
    } else {
        console.log('Passwords don\'t match, please try again.')
        setPassword()
    }
})
