Typed GraphQL queries for Pydantic models

Strawberry GraphQL Resolver turns a Pydantic model into a fluent query builder and a generated Strawberry GraphQL resolver.

The short version

Define a Queryable model, compose filters with normal Python operators, and submit it. On the server, decorate a handler with resolve_query.

users = User.where(User.age >= 18).sort(-User.age).submit()

@resolve_query(db=DBType.SQL)
def users(self, query: SQLQuery) -> list[User]:
    return repository.fetch(query)

Why this project?

  • Typed: query fields are derived from Pydantic models.
  • Composable: filters and sort expressions can be combined fluently.
  • GraphQL-native: query expressions serialize to GraphQL documents and variables.
  • Backend-aware: the same expression can compile to SQL Server or MongoDB.
  • Testable: unit and Testcontainers-backed system tests are included.
