# Chowkidar
### JWT Authentication for Django Graphene
[](LICENSE)
[](https://pypi.org/project/chowkidar-graphene/)
An JWT-based authentication package for Django [Graphene](https://github.com/graphql-python/graphene) GraphQL APIs.
### Features
* Support for [Graphene](https://github.com/graphql-python/graphene) GraphQL APIs
* Token & Refresh Token based JWT Authentication
* Tokens stored as server-side cookie
* Support for security measures - disable graphql introspection, get requests etc. on production
* Support for restricting 1 device / 1 login for a user
* Support for logging IP & User-Agent of user
* Ability to Auto-Refresh JWT Token if the Refresh Token Exists
* Support for Social Auth via Google Identity Service
* Support for Social Auth with [social-app-django](https://github.com/python-social-auth/social-app-django)
* Support for Authenticated GraphQL Subscriptions with Django Channels
* Support for file uploads adhering to [GraphQL Multipart Request Spec](https://github.com/jaydenseric/graphql-multipart-request-spec)
* Get current logged-in user instance in info.context of resolvers
### Installation
Install the package -
```bash
pip install chowkidar-graphene
```
Add `chowkidar` to `INSTALLED_APPS` and run migrations to apply required db changes to the database.
In `urls.py`, replace the GraphQLView coming from the Ariadne with the one from this package
```python3
from chowkidar.graphql import GraphQLView
```
```python3
urlpatterns = [
path('admin/', admin.site.urls),
path('graphql/', GraphQLView.as_view(schema=schema), name='graphql'),
...
]
```
Add the package to Graphene Middleware in `settings.py`
```python
GRAPHENE = {
'SCHEMA': 'framework.graphql.schema.schema',
'MIDDLEWARE': [
'chowkidar.auth.ChowkidarAuthMiddleware',
'graphene_django.debug.DjangoDebugMiddleware'
],
}
```
Add the mutations to your schema
```python3
from chowkidar.graphql import AuthMutations, SocialAuthMutations
class Mutation(
AuthMutations,
SocialAuthMutations,
...
):
pass
schema = graphene.Schema(mutation=Mutation, query=Query)
```
### Auth Decorators
Chowkidar supports 2 decorators that you can use in your API resolvers
```python3
from chowkidar.graphql import login_required, fingerprint_required, resolve_user
@login_required
def resolve_field(self, info, sport=None, state=None, count=5, after=None):
userID: str = info.context.userID
some_function()
@fingerprint_required
def resolve_field(self, info, sport=None, state=None, count=5, after=None):
refreshToken = info.context.refreshToken
userID: str = info.context.userID
some_function()
@resolve_user()
def mutate(self, info):
user: User = info.context.user
userID: str = info.context.userID
some_update()
```
1. **`@login_required`** - checks if user is authenticated, and passes down his/her userID at
info.context.userID. Does not hit the db.
2. **`@fingerprint_required`** - checks the refresh token of the user against db after validating its
fingerprint and returns info.context.userID & info.context.refreshToken
3. **`@resolve_user`** - checks if user is authenticated, and passes down his/her instance at info.context.user
as well as his ID at info.context.userID. Hits the db to get the user instance.
Both of these decorators, when wrapped around a query/mutation/type resolver, ensures that only logged-in users
can access it, when it is an unauthenticated request it shall
throw exception - `PermissionDenied(message='User not authenticated', code='AUTHENTICATION_REQUIRED')`
### GraphQL Subscriptions with Django Channels
In your `routing.py` -
```python3
from django.urls import path
from channels.routing import URLRouter, ProtocolTypeRouter
from chowkidar.graphql import AuthenticatedChannel
from .graphql.schema import schema # replace this with your schema
application = ProtocolTypeRouter(
{
"websocket": (
URLRouter(
[path("ws/", AuthenticatedChannel(schema, debug=True))]
)
),
}
)
```
Doing this, you will get the logged-in user instance at `info.context['user']`,
which you can handle as per your wish. You can also use the `@login_required` decorator
that comes along with this package.
### Mutations
Our Mutations (& GraphQL APIs) for auth may be not implemented according to basic graphql standards,
primarily because of technicalities involved in doing certain procedures (like setting up the cookie).
**Login a user**
- `success`, and `id` + `username` of the user are compulsory for the mutations to work.
```graphql
mutation {
authenticateUser(email: "aswinshenoy65@gmail.com", password: "<MY_PASSWORD>") {
success
user {
id
username
}
}
}
```
* **note**: `user { id username }` is a required selection for the authentication to happen.
Without id & username fields, it will not resolve & return 500.
You may use `username` variable to send email as well. However, you cannot do vice-versa.
```graphql
mutation {
authenticateUser(username: "aswinshenoy65@gmail.com", password: "<MY_PASSWORD>") {
success
user {
id
username
}
}
}
```
on success the following is returned, and 3 cookies (REFRESH_TOKEN & ACCESS_TOKEN) are set -
```json
{
"data": {
"authenticateUser": {
"success": true,
"user": {
"id": "2441264196336223233",
"username": "aswinshenoy"
},
"refreshExpiresIn": "2020-11-21T01:21:51.848Z"
}
}
}
```
**Social Auth**
* mostly same as `authenticateUser` but sends `accessToken`+`provider` instead of `email/username` + `password`
```graphql
mutation {
socialAuth(accessToken: "<SOME TOKEN>", provider: "<SOCIAL_AUTH_PROVIDER>"){
success
user
{
id
username
}
}
}
```
**Google Auth**
* mostly same as `authenticateUser` but sends `accessToken` instead of `email/username` + `password`
```graphql
mutation {
gAuth(accessToken: "<SOME TOKEN>"){
success
user
{
id
username
}
}
}
```
**Logout a user**
This is required since the cookies are server-side, and needs to be removed.
```graphql
mutation {
logoutUser
}
```
**View sessions of a user**
```graphql
{
mySessions{
isActive
token
userAgent
ip
issued
revoked
}
}
```
**Revoke Token**
Revoke a given refresh token of the user
```graphql
mutation ($token: String!){
revokeToken(token: $token)
}
```
**Revoke Other Tokens**
Revoke all tokens except the current token. Useful to logout user from all other devices
```graphql
mutation {
revokeOtherTokens
}
```

REVOKE_OTHER_TOKENS_ON_AUTH_FOR_USER = 'chowkidar.auth.rules.check_if_other_tokens_need_to_be_revoked'
# function that gets called with auth object after a successful GAuth

LOG_USER_IP_IN_REFRESH_TOKEN = True
LOG_USER_AGENT_IN_REFRESH_TOKEN = True
GOOGLE_AUTH_CLIENT_ID = 'blah1blah2.apps.googleusercontent.com'
```
#### FAQ
**1. How to know whether RefreshToken has expired in the frontend?**
0. When you do login using the API, we send back `refreshExpiresIn` on success.
1. Create a local cookie with expire time set to this `refreshExpiresIn`, with some value.
2. Before you send any authentication required requests (or before you open a auth required page), check whether this cookie exists.
**2. Do I need to refresh the access token?**
No, as long as you send both refresh token and the access token in the request (which you should automatically,
since its a server side cookie) the server will perform the refresh if a valid refresh token exists either when
approaching expiry of access token, or when having an expired access token. In both cases, the actual query shall
also be properly resolved and not failed. :)
