在Windows中同步读取stdin

Question

I've been doing this to synchronously read the whole stdin data under Linux:

var buffer = fs.readFileSync('/dev/stdin');

This obviously won't work on Windows since there is no /dev/stdin file. What could I do to achieve the same?

Answer 1

var size = fs.fstatSync(process.stdin.fd).size;
var buffer = size > 0 ? fs.readSync(process.stdin.fd, size)[0] : '';

Answer 2

The module readline-sync do the job very well.

npm install readline-sync

and then:

var readlineSync = require('readline-sync');
var answer = readlineSync.question('What is your favorite food? :');
console.log('Oh, so your favorite food is ' + answer);
