[nodejs] A simple example how to write to a file from stdin using stream.

node-fs-write-from-stdin.js

// from: http://book.mixu.net/node/ch9.html

'use strict';

const fs = require('fs');

const file = fs.createWriteStream('./output.txt');
process.stdin.pipe(file);

// stdin is paused by default
process.stdin.resume();

// then type things into stdin
// to complete, as far as I know, hit ^D (Ctrl-D) when cursor is at the start of the line to send EOF
