A NodeJS sample using Pipe that automatically logs whatever the user types in the console.

piping-text.js

const { createWriteStream } = require('fs');

const writeStream = createWriteStream('./file-test.txt');

// using stdin, stream and pipe, this will automatically log all the text you will type
process.stdin.pipe(writeStream);

process.stdin.on('data', (data) => {
    if (data.toString().toLowerCase().trim() === 'exit>this') {
        process.exit();
    }
});
