Django Ariadne JWT

Support for JWT based authentication for use with the ariadne graphql library running inside a Django project. It is heavily inspired by django-graph-jwt.

Installation

pip install django-ariadne-jwt

How to use

django-ariadne-jwt aims to be easy to install and use.

First add JSONWebTokenBackend to your AUTHENTICATION_BACKENDS

AUTHENTICATION_BACKENDS = [
  "django_ariadne_jwt.backends.JSONWebTokenBackend",
  # Any other authentication backends...
  "django.contrib.auth.backends.ModelBackend",
]

Then add JSONWebTokenMiddleware to your view

from django_ariadne_jwt.middleware import JSONWebTokenMiddleware

urlpatterns = [
  # Your other paths...
  path(
      "graphql/",
      csrf_exempt(
          GraphQLView.as_view(
              schema=schema, middleware=[JSONWebTokenMiddleware()]
          )
      ),
      name="graphql"
  )
]

Or to your queries:

ariadne.graphql_sync(
    schema,
    {
        "query": """
        query {
            test
        }
        """
    },
    middleware=[JSONWebTokenMiddleware()],
)

And then add the login_decorator to your resolvers before adding the field:

from django_ariadne_jwt.decorators import login_required

@query_type.field("test")
@login_required
def resolve_test(*args):
  ...

This will prevent the field from resolving and ariadne will add an error to the query result.

Finally add the type definitions and resolvers to the executable schema

from django_ariadne_jwt.resolvers import (
  auth_token_definition,
  auth_token_verification_definition,
  resolve_token_auth,
  resolve_refresh_token,
  resolve_verify_token,
)

type_definitions = """
  ...

  type Mutation {
    ...
    tokenAuth(username: String!, password: String!): AuthToken!
    refreshToken(token: String!): AuthToken!
    verifyToken(token: String!): AuthTokenVerification!
    ...
  }
"""

auth_type_definitions = [
  auth_token_definition,
  auth_token_verification_definition,
]

resolvers = [
  ...
]

auth_resolvers = [
  resolve_token_auth,
  resolve_refresh_token,
  resolve_verify_token,
]

schema = ariadne.make_executable_schema(
  [type_definitions] + auth_type_definitions, resolvers + auth_resolvers
)

Once you get an auth token, set the HTTP Authorization header to:

Token <token>

How to contribute

django-ariadne-jwt is at a very early stage. It is currently missing documentation, better testing and a lot of configuration options. Pull requests with any of these are greatly appreciated.
