Sanic-GraphQL

Adds GraphQL support to your Sanic application.

Based on flask-graphql by Syrus Akbary.

Usage

Just use the GraphQLView view from sanic_graphql

from sanic_graphql import GraphQLView

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')

This will add /graphql endpoint to your app.

Sharing eventloop with Sanic

In order to pass Sanic’s eventloop to GraphQL’s AsyncioExecutor, use before_start listener:

@app.listener('before_server_start')
def init_graphql(app, loop):
    app.add_route(GraphQLView.as_view(schema=Schema, executor=AsyncioExecutor(loop=loop)), '/graphql')

Supported options

• 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 to the graphql() function. By default is set to dict with request object at key request.
• root_value: The root_value you want to provide to executor.execute.
• pretty: Whether or not you want the response to be pretty printed JSON.
• executor: The Executor that you want to use to execute queries. If an AsyncioExecutor instance is provided, performs queries asynchronously within executor’s loop.
• graphiql: If True, may present GraphiQL when loaded directly from a browser (a useful tool for debugging and exploration).
• graphiql_template: Inject a Jinja template string to customize 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)

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
