Create a GraphQL over WebSocket endpoint with graphqlws

graphqlws-1.go

package main

import (
	"net/http"

	"github.com/functionalfoundry/graphqlws"
	"github.com/graphql-go/graphql"
)

func main() {
	// Create a GraphQL schema with a subscription object
	schema, err := graphql.NewSchema(graphql.SchemaConfig{
		Subscription: graphql.NewObject(...),
	})
	
	// Create a subscription manager
	subscriptionManager := graphqlws.NewSubscriptionManager(&schema)

	// Create a WebSocket/HTTP handler
	graphqlwsHandler := graphqlws.NewHandler(graphqlws.HandlerConfig{
		// Wire up the GraphqL WebSocket handler with the subscription manager
		SubscriptionManager: subscriptionManager,

		// Optional: Add a hook to resolve auth tokens into users that are
		// then stored on the GraphQL WS connections
		Authenticate: func(authToken string) (interface{}, error) {
			// This is just a dumb example
			return "Joe", nil
		},
	})

	// The handler integrates seamlessly with existing HTTP servers
	http.Handle("/subscriptions", graphqlwsHandler)
	http.ListenAndServe(":8080", nil)
