Adds GraphQL support to your Flask application.

Overview

Flask-GraphQL

Adds GraphQL support to your Flask application.

travis pypi Anaconda-Server Badge coveralls

Usage

Just use the GraphQLView view from flask_graphql

from flask import Flask
from flask_graphql import GraphQLView

from schema import schema

app = Flask(__name__)

app.add_url_rule('/graphql', view_func=GraphQLView.as_view(
    'graphql',
    schema=schema,
    graphiql=True,
))

# Optional, for adding batch query support (used in Apollo-Client)
app.add_url_rule('/graphql/batch', view_func=GraphQLView.as_view(
    'graphql',
    schema=schema,
    batch=True
))

if __name__ == '__main__':
    app.run()

This will add /graphql endpoint to your app and enable the GraphiQL IDE.

Special Note for Graphene v3

If you are using the Schema type of Graphene library, be sure to use the graphql_schema attribute to pass as schema on the GraphQLView view. Otherwise, the GraphQLSchema from graphql-core is the way to go.

More info at Graphene v3 release notes and GraphQL-core 3 usage.

Supported options for GraphQLView

  • schema: The GraphQLSchema object that you want the view to execute when it gets a valid request.
  • context: A value to pass as the context_value to graphql execute function. By default is set to dict with request object at key request.
  • root_value: The root_value you want to provide to graphql execute.
  • pretty: Whether or not you want the response to be pretty printed JSON.
  • graphiql: If True, may present GraphiQL when loaded directly from a browser (a useful tool for debugging and exploration).
  • graphiql_version: The graphiql version to load. Defaults to "1.0.3".
  • graphiql_template: Inject a Jinja template string to customize GraphiQL.
  • graphiql_html_title: The graphiql title to display. Defaults to "GraphiQL".
  • batch: Set the GraphQL view as batch (for using in Apollo-Client or ReactRelayNetworkLayer)
  • middleware: A list of graphql middlewares.
  • encode: the encoder to use for responses (sensibly defaults to graphql_server.json_encode).
  • format_error: the error formatter to use for responses (sensibly defaults to graphql_server.default_format_error.
  • subscriptions: The GraphiQL socket endpoint for using subscriptions in graphql-ws.
  • headers: An optional GraphQL string to use as the initial displayed request headers, if not provided, the stored headers will be used.
  • default_query: An optional GraphQL string to use when no query is provided and no stored query exists from a previous session. If not provided, GraphiQL will use its own default query.
  • header_editor_enabled: An optional boolean which enables the header editor when true. Defaults to false.
  • should_persist_headers: An optional boolean which enables to persist headers to storage when true. Defaults to false.

You can also subclass GraphQLView and overwrite get_root_value(self, request) to have a dynamic root value per request.

class UserRootValue(GraphQLView):
    def get_root_value(self, request):
        return request.user

Contributing

Since v3, flask-graphql code lives at graphql-server repository to keep any breaking change on the base package on sync with all other integrations. In order to contribute, please take a look at CONTRIBUTING.md.

  • How to get request headers when resolving field?

    How to get request headers when resolving field?

    What's the right way to get request header when resolving a query/mutation? A related issue, #17, lead me to believe that info.context.headers will work but I'm finding that doesn't exist when I try to print it:

     ❮❮❮ curl -i -H 'Content-Type: application/json' -H 'x-authorization-info: testing' -X POST -d '{"query": "query { latestSnapshot { url } }"}' http://localhost:5000/graphql
    HTTP/1.0 200 OK
    Content-Type: application/json
    Content-Length: 160
    Server: Werkzeug/0.14.1 Python/3.6.7
    Date: Thu, 18 Apr 2019 22:21:51 GMT
    
    {"errors":[{"message":"'dict' object has no attribute 'headers'","locations":[{"line":1,"column":9}],"path":["latestSnapshot"]}],"data":{"latestSnapshot":null}}% 
    

    with a resolver of:

        def resolve_latest_snapshot(self, info: ResolveInfo, org_id: Optional[int] = None) -> models.Snapshot:
            print(info.context.headers)
            # more stuff
    

    I have flask-graphql version 2.0.0.

    EDIT: other related packages I have:

    graphene==2.1.3
    graphql-core==2.1
    graphql-relay==0.4.5
    graphql-server-core==1.1.1

  • Use context option (if provided)

    Use context option (if provided)

    Related to https://github.com/graphql-python/flask-graphql/issues/18

    Currently, the GraphQLView class accepts the context keyword argument when initializing, but it's not using it to set the context_value when executing the query.

    This PR modifies the get_context instance method inside GraphQLView so that the context option is used when it is provided, defaulting to request otherwise.

  • Flask-GraphQL now returns warnings when using `graphql-core

    Flask-GraphQL now returns warnings when using `graphql-core

    Now that the minimum version of graphql-core was bumped to >=2.3 we're now seeing warnings returning when running tests that leverage Flask-GraphQL.

    Here's the relevant diff between graphql-core 2.2.1 and 2.3: https://github.com/graphql-python/graphql-core/compare/v2.2.1...v2.3.0#diff-a2c439ae03cccc507934c1377530d14aL74-L87

    In graphqlview.py - arguments are being passed as root and context though it seems these arguments are getting deprecated in favor of root_value and context_value.

    https://github.com/graphql-python/flask-graphql/blob/0137ca1315d811a7e01a1d256e41c74bc1c3fc2c/flask_graphql/graphqlview.py#L92-L93

    Here's the relevant DeprecationWarning

    DeprecationWarning: The 'context' alias has been deprecated. Please use 'context_value' instead.
    DeprecationWarning: The 'root' alias has been deprecated. Please use 'root_value' instead.

    Upgrade to graphql-core v3

    Hi, I'm currently looking at upgrading an application to graphql-core v3 (graphql-core-next) and I was wondering if there are any plans to create a version that would be compatible.

    Besides this package there's graphene as the main dependency and they have released a pre-release that is compatible with graphql-core v3

    graphql-core 3.0.0 was just released 3 days ago and now my builds are breaking. I have had to specify graphql-core==2.2.1 in my requirements.txt to fix this. I'm guessing that the Flask-Graphql module dependencies need updated to prevent graqhql-core>=3.
