• Version: v10.2.1
• Platform: Linux and macOS
• Subsystem: readline

The use case is that a node script is being run from a piped bash script and so process.stdin is the pipe and /dev/tty must be used explicitly to get user input.

var readline = require('readline'); var input = require('fs').createReadStream('/dev/tty'); var rl = readline.createInterface({ input: input , output: process.stdout //, terminal: false }); rl.question("This is the prompt: ", function (response) { console.log("This is the response:", response); rl.close(); // If I don't close the input explicitly, it stays open. input.close(); });

Output:

This is the prompt: yay yay This is the response: yay 

Uncommenting terminal: false solves the issue of echoing, but creates a new problem in that it no longer treats stdout as a proper terminal.
