Sequelize how to check if entry exists in database

Question

I need to check if entry with specific ID exists in the database using Sequelize in Node.js

  function isIdUnique (id) {
    db.Profile.count({ where: { id:          


        

Answer 1

I found the answer by @alecxe to be unreliable in some instances, so I tweaked the logic:

function isIdUnique (id, done) {
  db.Profile.count({ where: { id: id } })
  .then(count => {
    return (count > 0) ? true : false
  });
}
