How to use this package

Run go get github.com/TripleMint/gqlgenc to install the executable and update your go.mod and go.sum files.

To prevent go mod tidy from removing this library, add a tools.go file with the following code:

// +build tools

package tools

import (
	_ "github.com/TripleMint/gqlgenc"
)

Add a .gqlgenc.yml configuration file in the directory where queries are stored. Then run GRAPHQL_HOST=$HOST gqlgenc. You should see files generated in the directories you have specified in the configuration file.

What is gqlgenc ?

This is Go library for building GraphQL client with gqlgen

Motivation

Now, if you build GraphQL api client for Go, have choice:

• github.com/shurcooL/graphql
• github.com/machinebox/graphql

These libraries are very simple and easy to handle. However, as I work with gqlgen and graphql-code-generator every day, I find out the beauty of automatic generation. So I want to automatically generate types.

Installation

go get -u github.com/TripleMint/gqlgenc

How to use

Client Codes Only

gqlgenc base is gqlgen with plugins. So the setting is yaml in each format. gqlgenc can be configured using a .gqlgenc.yml file

Load a schema from a remote server:

model:
  package: generated
  filename: ./models_gen.go # https://github.com/99designs/gqlgen/tree/master/plugin/modelgen
client:
  package: generated
  filename: ./client.go # Where should any generated client go?
models:
  Int:
    model: github.com/99designs/gqlgen/graphql.Int64
  Date:
    model: github.com/99designs/gqlgen/graphql.Time
endpoint:
  url: https://api.annict.com/graphql # Where do you want to send your request?
  headers:　# If you need header for getting introspection query, set it
    Authorization: "Bearer ${ANNICT_KEY}" # support environment variables
query:
  - "./query/*.graphql" # Where are all the query files located?

Load a schema from a local file:

model:
  package: generated
  filename: ./models_gen.go # https://github.com/99designs/gqlgen/tree/master/plugin/modelgen
client:
  package: generated
  filename: ./client.go # Where should any generated client go?
models:
  Int:
    model: github.com/99designs/gqlgen/graphql.Int64
  Date:
    model: github.com/99designs/gqlgen/graphql.Time
schema:
  - "schema/**/*.graphql" # Where are all the schema files located?
query:
  - "./query/*.graphql" # Where are all the query files located?

Execute the following command on same directory for .gqlgenc.yml

gqlgenc

With gqlgen

Do this when creating a server and client for Go. You create your own entrypoint for gqlgen. This use case is very useful for testing your server.

package main

import (
	"fmt"
	"os"

	"github.com/TripleMint/gqlgenc/clientgen"

	"github.com/99designs/gqlgen/api"
	"github.com/99designs/gqlgen/codegen/config"
)

func main() {
	cfg, err := config.LoadConfigFromDefaultLocations()
	if err != nil {
		fmt.Fprintln(os.Stderr, "failed to load config", err.Error())
		os.Exit(2)
	}
	queries := []string{"client.query", "fragemt.query"}
	clientPackage := config.PackageConfig{
		Filename: "./client.go",
		Package:  "gen",
	}

	clientPlugin := clientgen.New(queries, clientPackage)
	err = api.Generate(cfg,
		api.AddPlugin(clientPlugin),
	)
	if err != nil {
		fmt.Fprintln(os.Stderr, err.Error())
		os.Exit(3)
	}
}

Pre-conditions

clientgen is created based on modelgen. So if you don't have a modelgen, it may be a mysterious move.
