Mongoose schema: validate before set

I want to validate a field before setting it, but my current code runs the validator after setting it. Is there a way to do it the other way around?

  password: { 
    type: String,
    required: true,
    validate: {
      validator: function(password) {
        return password.length > 9;
      }
    },
    set: v => encryptPassword(v)

This code checks the encrypted password's length but I want to check the unencrypted password's length.

Use pre middleware:

schema.pre('save', function(next) {
  this.password = /*encrypted password algorithm*/;
  next();
});

The validator will run before the pre middleware, so you encrypt the password after having validated the password. We use a regular function because we need access to this, and I'm not sure what kind of password encryption you're using.
