[![Build Status](https://travis-ci.org/graph-gophers/graphql-transport-ws.svg?branch=master)](https://travis-ci.org/graph-gophers/graphql-transport-ws)

**(Work in progress!)**

A Go package that leverages WebSockets to transport GraphQL subscriptions, queries and mutations implementing the [[email protected] protocol](https://github.com/apollographql/subscriptions-transport-ws/blob/v0.9.4/PROTOCOL.md)

### Use with graph-gophers/graphql-go

To use this library with [github.com/graph-gophers/graphql-go](https://github.com/graph-gophers/graphql-go) you can wrap the `relay` handler it provides the following way:

```go

package main

import (

	"fmt"

	"net/http"

	graphql "github.com/graph-gophers/graphql-go"

	"github.com/graph-gophers/graphql-go/relay"

	"github.com/graph-gophers/graphql-transport-ws/graphqlws"

)

const schema = `

	schema {

		subscription: Subscription

	}

	type Subscription {

		...

	}

`

type resolver struct {

	// ...

}

func main() {

	// init graphQL schema

	s, err := graphql.ParseSchema(schema, &resolver{})

	if err != nil {

		panic(err)

	}

	// graphQL handler

	graphQLHandler := graphqlws.NewHandlerFunc(s, &relay.Handler{Schema: s})

	http.HandleFunc("/graphql", graphQLHandler)

	// start HTTP server

	if err := http.ListenAndServe(fmt.Sprintf(":%d", 8080), nil); err != nil {

		panic(err)

	}

}

```
