I am experimenting with the code below, for testing how does child_process.exec() in node.js handle standard input from user.

import { exec } from 'child_process';
exec('powershell "$userInput = Read-Host;"', (err, stdout, stderr) => {
  if(err) throw err;
  console.log(stdout);
  console.log(stderr);
});

When I ran this through node main.js, the terminal is running forever with no output.

It seems that the exec() function creates a new shell waiting for user to type in it. However, I was unable to find the place to do so.

So I wonder if there are some ways to show that place or to handle this problem without the need to use Read-Host to receive user input.
