Expand description

Handler for GraphQL subscriptions.

Note: For HTTP/1.1 requests, this handler requires the request method to be GET; in later versions, CONNECT is used instead. To support both, it should be used with any.

RequestId, Option<Subject> and AcceptLanguage will be added to the GraphQL context before executing the request on the schema.

This handler expects two extensions:

  • Schema<Query, Mutation, Subscription> with the GraphQL Schema
  • RequestId with the request id (see RequestIdLayer)

And optionally:

Authentication will be performed using the same criteria than Auth extractor, retrieving the Cookie from the GET request and the token from the GQL_CONNECTION_INIT message.
