strawberry-django-jwt 0.1.1.dev1624299562

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 JSONWebTokenMiddleware middleware to your STRAWBERRY schema definition:

   from strawberry_django_jwt.middleware import JSONWebTokenMiddleware
   from strawberry import Schema
   
   schema = Schema(...)
   schema.middleware.extend([
        JSONWebTokenMiddleware(),
   ])
   

4. Add JSONWebTokenBackend backend to your AUTHENTICATION_BACKENDS:

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

5. 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=...)
   

6. [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))),
    ]

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


def auth_field(fn=None):
    return strawberry.field(login_required(fn))


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

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

Please note the info argument, without which strawberry would not provide the context info required for authentication. An alternative approach to this problem is following:

import strawberry
from strawberry.types import Info
from strawberry_django_jwt.decorators import login_required, login_field
from strawberry_django_jwt.mixins import RequestInfoMixin


@strawberry.type
class Query(RequestInfoMixin):
    @login_field
    def hello(self) -> str:
        # self == { 'info': ... } in this case
        return "World"

    @strawberry.field
    @login_required
    def foo(self) -> str:
        # self == { 'info': ... } in this case
        return self.get("info").field_name

    @strawberry.field
    @login_required
    def explicit_foo(self, info: Info) -> str:
        # self == { } in this case
        return info.field_name

RequestInfoMixin automatically injects info arguments to all fields in the class.

All function arguments that are not present in the definition will be added by the login_required decorator to the self dictionary as kwargs.
