Here is a simple function I created when once I kept working on a project where I constantly needed to get today, yesterday, and tomorrow's date in this format.

function returnYYYYMMDD(numFromToday = 0){
  let d = new Date();
  d.setDate(d.getDate() + numFromToday);
  const month = d.getMonth() < 9 ? '0' + (d.getMonth() + 1) : d.getMonth() + 1;
  const day = d.getDate() < 10 ? '0' + d.getDate() : d.getDate();
  return `${d.getFullYear()}-${month}-${day}`;
}

console.log(returnYYYYMMDD(-1)); // returns yesterday
console.log(returnYYYYMMDD()); // returns today
console.log(returnYYYYMMDD(1)); // returns tomorrow

Can easily be modified to pass it a date instead, but here you pass a number and it will return that many days from today.
