Chalice-GraphQL

Adds GraphQL support to your AWS Chalice application.

Installation

Install the Chalice integration with:

pip install graphql-server[chalice]

Usage

Use the GraphQLView from graphql_server.chalice.

from chalice import Chalice
from graphql_server.chalice import GraphQLView

from schema import schema

app = Chalice(app_name="MyApp")

@app.route("/graphql", methods=["GET", "POST"])
def graphql_server():
    view = GraphQLView(schema=schema, graphiql=True)
    return view.execute_request(app.current_request)

CORS

To allow CORS, create a CORSConfig and pass it when defining the route:

from chalice import CORSConfig

cors_config = CORSConfig(allow_origin="*")
@app.route("/graphql", methods=["GET", "POST"], cors=cors_config)
def graphql_server():
    view = GraphQLView(schema=schema, graphiql=True)
    return view.execute_request(app.current_request)

This adds a /graphql route with GraphiQL enabled.

Supported options for GraphQLView

• schema
• graphiql
• graphql_ide
• allow_queries_via_get

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
