HttpRequestComposer transforms a GraphQL request in a HttpRequest. Typically, this involves building a Json with "query" and "variables" fields but implementations can decide to customize this behaviour. For an example:

HttpResponse

class HttpResponse

an HTTP Response.

UploadsHttpBody

class UploadsHttpBody(uploads: Map<String, Upload>, operationByteString: ByteString) : HttpBody

WebSocketPayloadComposer

@ApolloExperimental

interface WebSocketPayloadComposer

WebSocketPayloadComposer transforms a GraphQL request in a payload to be sent in a WebSocket message
