mongoose-unique-validator not working?

Posted on December 24, 2019 Updated on December 24, 2019

Are you using the mongoose-unique-validator package and not getting any errors when you post duplicate objects?

CURRENT

const personSchema = new mongoose.Schema({name:String,number: String})
personSchema.plugin(uniqueValidator)

SOLUTION

You need to set a unique attribute on the key you want uniqueness with. By default mongo only adds uniqueness to the __id key

const personSchema = new mongoose.Schema({name: {type:String, unique: true}, number: String})
