p-readline

p-readline is a Promise-based version of the readline module in node.

Install

npm install --save p-readline

or

yarn add p-readline

Usage

The api is extremely simple:

const ask = require("p-readline")

ask("How are you?").then(answer => console.log(`I'm glad you feel ${answer}`))

If you are inside an async function you can also use the await notation

const ask = require("p-readline")

async function myAsyncFunc() {
    const answer = await ask("How are you?")
    console.log(`I'm glad you feel ${answer}`)
}

myAsyncFunc()
