Make sure you have a working Go environment. To install graphql, simply run:

$ go get github.com/cusspvz/graphql

Usage

import "context"

const reqDoc := `
    query ($key: String!) {
        items (id:$key) {
            field1
            field2
            field3
        }
    }
`

type reqStructure struct {
    items struct {
        field1 string
        field2 string
        field3 string
    }
}


func main() {

    // create a client (safe to share across requests)
    client := graphql.NewClient("https://cusspvz.io/graphql")

    // make a request
    req := graphql.NewRequest(reqDoc)

    // set any variables
    req.Var("key", "value")

    // set header fields
    req.Header.Set("Cache-Control", "no-cache")

    // define a Context for the request
    ctx := context.Background()

    // run it and capture the response
    var respData reqStructure
    if err := client.Run(ctx, req, &respData); err != nil {
        log.Fatal(err)
    }

    //subscribe 

    subClient, err := client.SubscriptionClient(ctx, req.Header)
    if err != nil {
        log.Fatal(err)
    }


    sub, err := subClient.Subscribe(`
        subscription {
    `)
}

File support via multipart form data

By default, the package will send a JSON body. To enable the sending of files, you can opt to use multipart form data instead using the UseMultipartForm option when you create your Client:

client := graphql.NewClient("https://cusspvz.io/graphql", graphql.UseMultipartForm())

For more information, read the godoc package documentation or the blog post.
