How to just check if the mongodb .find returns something or not so true or false-CodePudding

How to find out if the .find returns something or not? I'm trying to make it so if it returns nothing, it saves a schema with an auth token (check 2), and if it returns something it does check 3. But everytime, even when I do not have a schema with my discordId in the database it logs check 3 and check 1 but never check 2.

let discordId = message.author.id;
const discordIdCheck = authSchema.find({
  discordId: discordId,
});
console.log('check 1');
if (discordIdCheck.count() < 1) {
  function getAuthToken() {
    var letters =
      '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!.#&';
    var authTokenStart = '';
    for (var i = 0; i < 12; i  ) {
      authTokenStart  = letters[Math.floor(Math.random() * letters.length)];
    }
    return authTokenStart;
  }

  const authToken = getAuthToken();

  const auth = {
    discordId: discordId,
    authToken: authToken,
  };
  console.log('check 2');
  message.author.send('Okay, your auth token is: '   authToken);
  console.log(authToken);
  new authSchema(auth).save();
} else {
  message.channel.send(
    'You already have an auth token. use !token to make me send it to you in your direct messages',
  );
  console.log('Check 3 ');
}

CodePudding user response：

You can use the length value to check the length of the find() result like:

const discordIdCheck = await authSchema.find({
  discordId: discordId,
});

if(discordIdCheck.length <= 0) console.log("0 found")
