Want to make correct UserSchema for BlogWebsite

hello guys,
I have UserSchema that has 3 fields right now (email, password, username) . I want Username not to be required:true, and Username.value equals to email.value by default. Help me please who knows how to solve this.
Or maybe it will be better to create separate schema Email for both fields??

Hi @Oleg_Khalanskii,

You can do this with pre middleware. You can do it like this:

const UserSchema = new Schema({
  email: { type: String, required: true, unique: true },
  password: { type: String, required: true },
  username: { type: String } 

UserSchema.pre('save', (next) => {
  this.username = this.get('email');

You can read more here: Mongoose v6.9.1: Middleware.
