How to write plugins for gqlgen
[edit]
Plugins provide a way to hook into the gqlgen code generation lifecycle. In order to use anything other than the default plugins you will need to create your own entrypoint:
// +build ignore
package main
import (
"flag"
"fmt"
"io"
"log"
"os"
"time"
"github.com/99designs/gqlgen/api"
"github.com/99designs/gqlgen/codegen/config"
"github.com/99designs/gqlgen/plugin/stubgen"
)
func main() {
cfg, err := config.LoadConfigFromDefaultLocations()
if err != nil {
fmt.Fprintln(os.Stderr, "failed to load config", err.Error())
os.Exit(2)
}
err = api.Generate(cfg,
api.AddPlugin(yourplugin.New()), // This is the magic line
)
if err != nil {
fmt.Fprintln(os.Stderr, err.Error())
os.Exit(3)
}
}
There are currently only two hooks:
Take a look at plugin.go for the full list of available hooks. These are likely to change with each release.
