GraphQLView view from
from aiohttp import web from aiohttp_graphql import GraphQLView from schema import schema app = web.Application() GraphQLView.attach(app, schema=schema, graphiql=True) # Optional, for adding batch query support (used in Apollo-Client) GraphQLView.attach(app, schema=schema, batch=True, route_path="/graphql/batch") if __name__ == '__main__': web.run_app(app)
This will add
/graphql endpoint to your app (customizable by passing
GraphQLView.attach) and enable the GraphiQL IDE.
GraphQLView.attach is just a convenience function, and the same functionality can be achieved with
gql_view = GraphQLView(schema=schema, graphiql=True) app.router.add_route('*', '/graphql', gql_view, name='graphql')
It's worth noting that the the "view function" of
GraphQLView is contained in
GraphQLView.__call__. So, when you create an instance, that instance is callable with the request object as the sole positional argument. To illustrate:
gql_view = GraphQLView(schema=Schema, **kwargs) gql_view(request) # <-- the instance is callable and expects a `aiohttp.web.Request` object.
GraphQLSchemaobject that you want the view to execute when it gets a valid request.
context: A value to pass as the
executefunction. By default is set to
dictwith request object at key
root_valueyou want to provide to graphql
pretty: Whether or not you want the response to be pretty printed JSON.
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
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
format_error: the error formatter to use for responses (sensibly defaults to
asyncmode 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.
