🍓Strawberry Persisted Queries

Apollo-compatible persisted queries for Strawberry.

Usage

Add PersistedQueriesExtension() to your extensions.

import strawberry
from strawberry_persisted_queries import PersistedQueriesExtension

schema = strawberry.Schema(
    query=Query,
    extensions=[
        PersistedQueriesExtension(),
    ],
)

Django

For Django users, a Django cache backend is available. This uses the default cache set in Django.

from strawberry_persisted_queries.django_cache import DjangoPersistedQueryCache

PersistedQueriesExtension(cache_backend=DjangoPersistedQueryCache())

Safelisted Queries

DictSafelist can be used to require persisted queries to already be saved. This can be used with a build tool to ensure only queries used within an app are available.

from strawberry_persisted_queries.safelisting import DictSafelist

PersistedQueriesExtension(safelist=DictSafelist({
    'sha256Hash': 'query {...}',
}))

Custom Cache Backends

Custom cache backends allow using another cache for persisted queries, such as memcached or a database. Custom cache backends can inherit from strawberry_persisted_queries.PersistedQueryCache.

from strawberry_persisted_queries.cache import PersistedQueryCache

class MyCache(PersistedQueryCache):
    def get(self, query_hash):
        return cache.get(query_hash)

    def set(self, query_hash, value):
        cache.set(query_hash, value)

PersistedQueriesExtension(cache_backend=MyCache())
