Demonstration of queries/mutations/defer/stream/subscriptions/live

Experimental GraphQL Playground

Demonstration of experimental GraphQL features with the following transports:

• graphql-helix - GraphQL over HTTP
• graphql-ws - GraphQL over WebSocket

Showcasing the following features with Fetcher implementations on GraphiQL:

• Query (HTTP, HTTP-Multipart, WebSocket)
• Mutation (HTTP, HTTP-Multipart, WebSocket)
• Query with @defer (HTTP-Multipart, WebSocket)
• Query with @stream (HTTP-Multipart, WebSocket)
• Subscription (WebSocket/SSE)
• Query with @live (WebSocket/SSE)

Powered by the following libraries:

• graphql-js - The JavaScript reference implementation for GraphQL
• SSE-Z - Simple SSE wrapper
• meros - Easy multiresponse parser
• graphql-live-query - GraphQL live queries for any GraphQL schema

Current issues

1. graphql-helix with SSE-Z does not propagate GraphQL validation errors to the client properly
