javascript - Node.js 中的固定位置命令提示符

Question

有没有办法将命令提示符(只是 question 提示符或类似的提示符)固定在终端底部，并使用 Node.js 在其上方记录输出.

一个非常糟糕的例子:

Your favourite food is sushi.
Your favourite food is chicken.
Your favourite food is okra.
--> What is your favourite food?

所以本质上，我希望用户始终能够输入，并在提示上方回显输入。

interface.question("What is your favourite food?", function(answer) {
    // output the answer above where this prompt was
    // and somehow keep this same prompt where is is
});

我希望在其中使用它的特定应用程序是一个简单的 IRC 客户端，我有一个位置供用户输入，并拥有所有输出(用户输入的内容，以及其他人也输入的内容)在用户输入的地方输出。下图中的线条是虚构的。

Serverline module

process.stdout.write("\x1Bc")
console.log(Array(process.stdout.rows + 1).join('\n'));

const myRL = require("serverline")

myRL.init()
myRL.getRL().question("What is your favourite food? ", function(answer) {
  console.log(`Your favourite food is ${answer}.`)
});

function main() {
  let i = 0
  setInterval(function() {
    const num = () => Math.floor(Math.random() * 255) + 1
    i++
    console.log(i + " " + num() + "." + num() + "." + num() + " user connected.")
  }, 700)
}
main()
