UI Helper(Connects UI with Server)

UI (Simple React Project that control Server)

Usage

• First, implement your DB interface

package main

import (
	gocon "github.com/ahmetask/go-con"
)

type CustomDB struct {
}

func (db *CustomDB) Save(config gocon.Config) error {

	return nil
}

func (db *CustomDB) Read(appName string) (*gocon.Config, error) {
	var config gocon.Config

	return &config, nil
}

func (db *CustomDB) ReadSpecs() ([]gocon.Spec, error) {

	return []gocon.Spec, nil
}

• Then run config server

configManager := gocon.ConfigManager{
	DbInstance:       &customDB,
	ConfigServerPort: "8080",
	BroadcastModuleConfig: gocon.BroadcastModuleConfig{
		Available: true,
		IsLocal:   false,
	},
}

err := configManager.Initialize()

panic(err)

• You can also add your own logger instance if you want. It's not necessary. Go-con uses default logger

• It also provides helper functions for Golang projects to control the server and client.

• if you use another programing languages use proto files to interract go-con server

• How to get the updated config? (See Client)

type Config struct {
	
}

var CustomConfig Config

go func() {
	err := gocon.ListenConfigChange("port", &CustomConfig, nil)
	fmt.Println(err)
}()

• It will listen config server and change your CustomConfig instance whenever update arrives.

• So that's all. Don't forget to look at the examples. You can change it according to your own wishes
