set field as empty for mongo object using mongoose

Question

I\'m calling user.save() on an object, where I set user.signup_date = null;

user.first_name = null;
user.signup_date = null;

user.save();

Answer 1

Another option is to define a default value as undefined for these properties.

Something like the following:

let userSchema = new mongoose.Schema({ first_name: { type: String, default: undefined }, signup_date: { type: Date, default: undefined } })
