Koanf Go allows to write dynamic configuration files for koanf configuration manager.

Koanf Go(lang)

Koanf Go(lang) allows to write dynamic configuration files for koanf configuration manager. Sometimes dynamic configuration is required.

Based on the idea of https://github.com/mdouchement/koanflua.

Usage

// config.go
package config

import (
	"maps" // https://github.com/containous/yaegi/issues/327
	"os"
)

func Load() (map[string]interface{}, error) {
	config := map[string]interface{}{
		"brokers": []string{"localhost:42", "localhost:4242"},
		"listen":  "localhost",
		"redis": map[string]interface{}{
			"addr":     "localhost:6379",
			"password": "trololo",
			"db":       1,
		},
	}

	if os.Getenv("MAGIC_FEATURE") == "enabled" {
		maps.Set(config, "feature", "testouille")
	}

	return config, nil
}

package main

import (
	"fmt"
	"log"

	"github.com/knadh/koanf"
	"github.com/knadh/koanf/providers/file"
	"github.com/mdouchement/koanfgo"
)

func main() {
	konf := koanf.New(".")
	err := konf.Load(file.Provider("config.go"), koanfgo.Parser())
	if err != nil {
		log.Fatal(err)
	}

	//

	redisAddr := konf.String("redis.addr")
	fmt.Println(redisAddr)
}
