@default

Using the @default directive you can specify a default value for the field.

The default value is applied if:

the event does not contain a payload field with the same name as the field that uses the directive AND
no other directive produces data for that field AND
the field that the directive is applied on is not nullable

All three conditions must be met for the default value to be applied.

Example

user.graphql

type User @upsertOn(...) {
    name: String! @default(value: "John Doe")
    friends: [String!]! @default(value: ["Jane Doe", "Max Mustermann"])
}

In this case, the name field will default to "John Doe" and the friends field will default to ["Jane Doe", "Max Mustermann"].

Limitations of the @default directive

The default directive cannot be used on fields that reference to other projections or CRUD types.
