strawberry-django-jwt 0.2.1.dev1645534178

Strawberry-graphql port of the graphene-django-jwt package

Strawberry Django JWT

JSON Web Token authentication for Strawberry Django GraphQL

---

Disclaimer

This project is a forked version of Django GraphQL JWT that substitutes Graphene GraphQL backend for Strawberry

---

Installation

1. Install last stable version from Pypi:

   pip install strawberry-django-jwt
   

2. Add AuthenticationMiddleware middleware to your MIDDLEWARE settings:

   MIDDLEWARE = [
       ...,
       'django.contrib.auth.middleware.AuthenticationMiddleware',
       ...,
   ]
   

3. Add following django apps to INSTALLED_APPS:

   INSTALLED_APPS = [
       'django.contrib.auth',
       'django.contrib.contenttypes',
       'django.contrib.sessions',
       ...,
   ]
   

   If using refresh tokens, also add strawberry_django_jwt.refresh_token

   INSTALLED_APPS = [
       'django.contrib.auth',
       'django.contrib.contenttypes',
       'django.contrib.sessions',
       ...,
       'strawberry_django_jwt.refresh_token',
       ...,
   ]
   

4. Add JSONWebTokenMiddleware or AsyncJSONWebTokenMiddleware middleware to your STRAWBERRY schema definition:

   from strawberry_django_jwt.middleware import JSONWebTokenMiddleware, AsyncJSONWebTokenMiddleware
   from strawberry import Schema
   
   # !! IMPORTANT !!
   # Pick only one, async middleware is needed when using AsyncGraphQLSchema
   schema = Schema(..., extensions=[
      JSONWebTokenMiddleware,
      AsyncJSONWebTokenMiddleware,
   ])
   

5. Add JSONWebTokenBackend backend to your AUTHENTICATION_BACKENDS:

   AUTHENTICATION_BACKENDS = [
       'strawberry_django_jwt.backends.JSONWebTokenBackend',
       'django.contrib.auth.backends.ModelBackend',
   ]
   

6. Add strawberry-django-jwt mutations to the root schema:

   import strawberry
   import strawberry_django_jwt.mutations as jwt_mutations
   
   @strawberry.type
   class Mutation:
       token_auth = jwt_mutations.ObtainJSONWebToken.obtain
       verify_token = jwt_mutations.Verify.verify
       refresh_token = jwt_mutations.Refresh.refresh
       delete_token_cookie = jwt_mutations.DeleteJSONWebTokenCookie.delete_cookie
   

   schema = strawberry.Schema(mutation=Mutation, query=...)

7. [OPTIONAL] Set up the custom Strawberry views

   These views set the status code of failed authentication attempts to 401 instead of the default 200.

   from django.urls import re_path
   from strawberry_django_jwt.decorators import jwt_cookie
   from strawberry_django_jwt.views import StatusHandlingGraphQLView as GQLView
   from ... import schema
   
   urlpatterns += \
   [
       re_path(r'^graphql/?$', jwt_cookie(GQLView.as_view(schema=schema))),
   ]
   

   or, for async views:

   from django.urls import re_path
   from strawberry_django_jwt.decorators import jwt_cookie
   from strawberry_django_jwt.views import AsyncStatusHandlingGraphQLView as AGQLView
   from ... import schema
   
   urlpatterns += \
   [
       re_path(r'^graphql/?$', jwt_cookie(AGQLView.as_view(schema=schema))),
   ]

Known Issues

• JWT_ALLOW_ANY_CLASSES

  • Only supports return-type based filtering at the moment, because strawberry does not use class-based field definitions (so all superclasses are dropped)

  • It might be possible to create a workaround by using either a class decorator or by creating a custom graphql scheme that somehow preserves class hierarchy of types

Example Application

To start the example application, install poetry dev dependencies (poetry install will suffice) and run poetry run uvicorn tests.example_app.asgi:application

Quickstart Documentation

===============Work in Progress===============

Relay support has been temporarily removed due to lack of experience with Relay

Most of the features are conceptually the same as those provided by Django GraphQL JWT

Authenticating Fields

Fields can be set to auth-only using the login_required decorator in combination with strawberry.field or via login_field

import strawberry
from strawberry.types import Info
from strawberry_django_jwt.decorators import login_required
from strawberry_django_jwt.decorators import login_field


@strawberry.type
class Query:
    @login_field
    def hello(self, info: Info) -> str:
        return "World"

    @strawberry.field
    @login_required
    def foo(self, info: Info) -> str:
        return "Bar"

    @strawberry.field
    @login_required
    def foo2(self) -> str:
        return "Bar2"

The info argument is optional. If not provided, the login_required decorator decorates the resolver function with a custom function with info.

All required function arguments that are not present in the definition (atm. only info) will be added by the login_required decorator to the self dictionary as kwargs.

Model Mutations

You can add the login_required decorator to them as well

import strawberry
from strawberry_django_jwt.decorators import login_required
from strawberry.django import mutations


@strawberry.type
class Mutation:
    foo_create: FooType = login_required(mutations.create(FooInput))
    foo_delete: FooType = login_required(mutations.update(FooPartialInput))
    foo_update: FooType = login_required(mutations.delete())

Async Views

Should be fully supported :)

import strawberry
from strawberry_django_jwt.decorators import login_field


@strawberry.type
class Query:
    @login_field
    async def foo(self) -> str:
        return "bar"

Other

The introspection query authentication can be controlled by setting JWT_AUTHENTICATE_INTROSPECTION
