有没有办法暂停一个运行脚本与process.stdin用于Node.js中的用户输入？

Question

我希望看看Node.js是否能够在遇到process.stdin块时暂停脚本以获取命令行应用程序的用户输入，类似于 prompt（）在浏览器中使用JS或获取如何在Ruby中工作。

  var response = '';

  console.log("What's your favorite color?");

  process.stdin.resume();
  process.stdin.setEncoding('utf8');

  process.stdin.on('data', function (text) {
    response = text;
    process.exit();
  });

  console.log(`Cool! So ${response} is your favorite color? Mine is black.`);

在上面的简单脚本中，我希望看到

What's your favorite color?
*pause for user input ===>* Red
Cool! So Red is your favorite color? Mine is black.

暂停脚本，直到我输入内容并按Enter键继续运行。相反，我看到了

What's your favorite color?
Cool! So  is your favorite color? Mine is black.

立即打印出来然后接受我的用户输入。

我知道还有其他模块，如 readline 和提示，可以简化节点的用户输入。对于这个问题，我特别想看看Node.js是否提供此功能而无需安装额外的软件包（process.stdin是首先想到的），尽管知道是否有任何模块会有所帮助也提供这种功能。

Answer 1

在继续编写脚本之前等待stdin

  var response = '';

  console.log("What's your favorite color?");

  process.stdin.resume();
  process.stdin.setEncoding('utf8');

  process.stdin.on('data', function (text) {
    response = text;
    console.log(`Cool! So ${response} is your favorite color? Mine is black.`);
    process.exit();
  });

Answer 2

您可以使用readline-sync。

var rl = require('readline-sync');
var response = '';

response = rl.question("What's your favorite color?");

console.log(`Cool! So ${response} is your favorite color? Mine is black.`);
