// Assuming you have imported and connected Mongoose to your MongoDB database

// Define a Mongoose model
const MyModel = mongoose.model('MyModel', new mongoose.Schema({
  // Schema definition
}));

// Query to check if a document exists
MyModel.exists({ /* condition */ }, (err, result) => {
  if (err) {
    console.error(err);
  } else {
    console.log(result); // true if document exists, false otherwise
  }
});
