Unique email (with unique username)

[cd4d]

Is it possible to enforce unique email and username at the same time? All I see in the doc is "usernameUnique" option.

In my project that option works and I get an error when I try to register a duplicate username, however it's still possible to register a user with the same email.

As per my knowledge, no you can't do that.

But, what you can do is set that in you model like this,

email: {
        type: String,
        unique: true
}

---

*Extra info:

• if "email" is not unique it will throw "duplicate key error"

• if you want to handle that error specifically, use this

if (err.name === 'MongoError' && err.code === 11000) {
        // handle error
 }

That's what I ended up using. I don't know why it's not implemented, as it's not unusual to enforce both unique values.
