This is Go library for building GraphQL client with gqlgen
Now, if you build GraphQL api client for Go, have choice:
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.
go get -u github.com/Yamashou/gqlgencgqlgenc 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?
generate:
clientV2: true # Generate a Client that provides a new signature
clientInterfaceName: "GithubGraphQLClient" # Determine the name of the generated client interfaceLoad 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?
generate:
clientV2: true # Generate a Client that provides a new signature
clientInterfaceName: "GithubGraphQLClient" # Determine the name of the generated client interfaceExecute the following command on same directory for .gqlgenc.yml
gqlgencor if you want to specify a different directory where .gqlgenc.yml file resides (e.g. in this example the directory is schemas):
gqlgenc generate --configdir schemasDo 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/Yamashou/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)
}

This client does not support subscription. If you need a subscription, please create an issue or pull request.
clientgen is created based on modelgen. So if you don't have a modelgen, it may be a mysterious move.
