A simple example how to use this module.

let fs = require('fs');
let Polly = require('polly-tts');
let polly = new Polly();
let options = {
    text: 'Hallo'
};
let fileStream = fs.createWriteStream('polly-tts.mp3');
polly.textToSpeech( options, ( err, audioStream ) => {
    if( err ) {
        return console.log(err.message);
    }
    audioStream.pipe(fileStream);
});
