graphql

Low-level GraphQL client for Go.

• Simple, familiar API
• Respects context.Context timeouts and cancellation
• Build and execute any kind of GraphQL request
• Use strong Go types for response data
• Use variables and upload files
• Simple error handling

Installation

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

$ go get github.com/machinebox/graphql

Usage

import "context"

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

// make a request
req := graphql.NewRequest(`
    query ($key: String!) {
        items (id:$key) {
            field1
            field2
            field3
        }
    }
`)

// 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 ResponseStruct
if err := client.Run(ctx, req, &respData); err != nil {
    log.Fatal(err)
}

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://machinebox.io/graphql", graphql.UseMultipartForm())

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