Type validation

You can define a type for a schema property passing a "type" parameter to it.

new Schema({ name: { type: String }})

Valid types are

  • String

  • Number (an integer or a gcloud.datastore.int())

  • Array

  • Object

  • Boolean

  • Date(*)

  • Buffer

  • Schema.Types.Double (a float or a gcloud.datastore.double())

  • Schema.Types.GeoPoint (a gcloud.datastore.geoPoint())

  • Schema.Types.Key (an entity Key)

(*) Valid Date are javascript Date instance (callingnew Date()) or any valid string date. If a string date is provided, it will automatically be parsed as Date object when saving the entity in the Datastore.

So back to our previous example of a User Model, we would probably have something like this.

const userSchema = new Schema({
name: { type: String },
lastname: { type: String },
password: { type: String },
email: { type: String },
company: { type: Schema.Types.Key, ref: 'Company' },
votes: { type: Number },
dateOfBirth: { type: Date },
createdOn: { type: Date },
modifiedOn: { type: Date }

Note: you are not forced to set a type, if you don't define one, then any type is valid.

const userSchema = new Schema({
name: {}, // any type
email: { type: String }
