Sweet & Sour mongoose.js methods – 3

A short snippet to assist in linking of social media accounts in a userschema when using mongoDB & mongoose.js

async function generateOrFindUser(accessToken, refreshToken, profile, done) {
    const email = profile.emails[0].value;
    const name = profile.displayName || profile.username;
    const facebookId = profile.id;
    if (email) {
      let updatedUser = await User.findOneAndUpdate({facebookId},{email,name,facebookId}, {'upsert': true, 'new': true}, done);
    } else {
        var emailError = new Error("Your email privacy settings prevent you from signing in.");
        done(emailError, null);
    }
}

User schema:

const UserSchema = new mongoose.Schema({
  email: {
    type: String,
    unique: true,
    required: true,
    lowercase: true
  },
  password: {
    type: String,
    required: true,
    trim: true,
    validate: validatePass
  },
  name: {
    type: String,
    unique: true,
    required: true,
    lowercase: true,
    trim: true,
    minlength: 4
  },
  phone: {
    type: Number,
    trim: true
  },
  question: {
    type: String,
    select: true
  },
  answer: {
    type: String,
    required: true,
    trim: true
  },
  status: {
    type: Boolean,
    required: true
  },
  date: {
    type: Date,
    default: Date.now
  },
  facebookId: {
      type : String
  }
});
