Dynamic Graphql Client Golang

Automaticly build graphql document from introspection query, query graphql like restful api.

Use operation name and variable to query graphql server, does not need document.

Use gjson to handle graphql response.

Currently under development, lack of test and some feature.

Features

1. Automaticly build graphql document from introspection query
2. support query, mutation and uploadMutation

Quick start

run a simple graphql server

go run example/server.go

run a query

package main

import (
    "context"
    "log"
    "github.com/Sczlog/dgql"
)

func main(){
	client, err := dgql.NewClient("http://localhost:8080/graphql")
    if err != nil {
        log.Fatal(err)
        return
    }
	resp, err := client.Query(context.Background(), "product", map[string]interface{}{
		"id": 1,
	}, nil)
    if err != nil {
        log.Fatal(err)
        return
    }
	println(resp.Raw)
    // response {"product":{"id":1,"info":"Chicha morada is a beverage originated in the Andean regions of Perú but is actually consumed at a national level (wiki)","name":"Chicha Morada","price":7.99}}
}

or mutation

package main

import (
	"context"
	"log"

	"github.com/Sczlog/dgql"
)

func main() {
	client, err := dgql.NewClient("http://localhost:8080/graphql")
	if err != nil {
		log.Fatal(err)
		return
	}
	resp, err := client.Mutation(context.Background(), "create", map[string]interface{}{
		"price": 100,
		"name":  "test",
		"info":  "test",
	}, nil)
	if err != nil {
		log.Fatal(err)
		return
	}
	println(resp.Raw)
	// response {"create":{"id":42007,"info":"test","name":"test","price":100}}
}
