In GraphQL you use queries to fetch data from a server. In Strawberry you can define the data your server provides by defining query types.
By default all the fields the API exposes are nested under a root Query type.
This is how you define a root query type in Strawberry:
@strawberry.type class Query: name: str schema = strawberry.Schema(query=Query)
This creates a schema where the root type Query has one single field called name.
As you notice we don't provide a way to fetch data. In order to do so we need to
resolver, a function that knows how to fetch data for a specific
For example in this case we could have a function that always returns the same name:
def get_name() -> str: return "Strawberry" @strawberry.type class Query: name: str = strawberry.field(resolver=get_name) schema = strawberry.Schema(query=Query)
So now, when requesting the name field, the
get_name function will be called.
