Simple Example
Target SDL
type User {
id: ID!
name: String!
}
type Query {
user(id: ID!): User
users: [User!]!
}import io.github.dexclaimation.soda.derive.obj
import io.github.dexclaimation.soda.schema.SodaObject
import sangria.schema.StringType
case class User(id: String, name: String)
// Using macro (More abstraction & limitations, faster to write)
object User {
final val t = obj[Repo, User]()
}
// Using regular traits (Clear, easier to debug, slower to write)
object User extends SodaObject[Repo, User]("User") {
def definition: Def = { t =>
t.id(of = _.id)
t.prop("name", StringType, of = _.name)
}
}import io.github.dexclaimation.soda.schema._
import sangria.schema.{IDType, OptionType, ListType, Dfe}
class Repo {
private val Users = Map("1" -> User("1", "Bob"))
def user(id: String): Option[User] =
Users get id
def products: List[Product] = Users.values.toList
}
object UserQuery extends SodaQuery[Repo, Unit] {
val id = $("id", IDType)
def definition: Def = { t =>
t.field("user", OptionType(User.t), args = id :: Nil) {
case Dfe(_, a, c) =>
c.user(a.arg(id))
}
t.field("users", ListType(User.t)) {
case Dfe(_, _, c) => c.users
}
}
}Get the final schema
import io.github.dexclaimation.soda.core.SchemaDefinition.makeSchema
