If you want to pipe something into a Node.js file, readline will read
everything from stdin and then close after the pipe has finished:
import { createInterface } from 'readline';
import processLine from './processLine';
const rl = createInterface(process.stdin);
rl.on('line', processLine);

an example
usage for inserting eslint-ignore-next-line comments based off of the eslint
cli output.
