Django Integration:

To use, import the view, then add to your list of urls (replace previous GraphQL view).

from graphene_file_upload.django import FileUploadGraphQLView

urlpatterns = [
  url(r'^graphql', FileUploadGraphQLView.as_view(graphiql=True)),
]

Flask Integration:

Note that flask-graphql version <2.0 is not supported. At the time of writing this README, you must install flask-graphql with pip install --pre flask-graphql

Simply import the modified view and create a new url rule on your app:

from graphene_file_upload.flask import FileUploadGraphQLView

app.add_url_rule(
    '/graphql',
    view_func=FileUploadGraphQLView.as_view(
      ...
    )
)
