Sanic-GraphQL

Adds GraphQL support to your Sanic application.

Based on flask-graphql by Syrus Akbary.

Usage

Use the GraphQLView view fromsanic_graphql

from sanic_graphql import GraphQLView
from sanic import Sanic

from schema import schema

app = Sanic(name="Sanic Graphql App")

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

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

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=8000)

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

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".
• jinja_env: Sets jinja environment to be used to process GraphiQL template. If Jinja’s async mode is enabled (by enable_async=True), uses Template.render_async instead of Template.render. If environment is not set, fallbacks to simple regex-based renderer.
• batch: Set the GraphQL view as batch (for using in Apollo-Client or ReactRelayNetworkLayer)
• middleware: A list of graphql middlewares.
• max_age: Sets the response header Access-Control-Max-Age for preflight requests.
• 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.
• enable_async: whether async mode will be enabled.
• 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
