objectbind

Object->files mapping, dynamic bind files, directory, etcd or other file-like backend to golang object

Simple Interface to Use

Bind bind the object to file or etcd
BindField receive field changes when the file or etcd is change
Save save the local object to remote

Distributed files supported

For example:

defaultConfig := struct {
    Name map[string]interface{}
    Data []map[string]interface{} `bind:"data/conf/test"`
}{}

objectbind.Bind(ctx, &defaultConfig, "conf/test.yaml")

conf/test.yaml will map to struct {Name map[string]interface{}}

data/conf/test.yaml will map to struct {Data []map[string]interface{}

example

package main

import (
	"context"
	"fmt"
	"github.com/ti/objectbind"
)

type Config struct {
	Name map[string]interface{}
	Data []map[string]interface{} `bind:"data/conf/test"`
	Data2 map[string]interface{}  `bind:"etc/data/conf2/"`
}


func main() {
	defaultConfig := Config{
		Name: map[string]interface{}{
			"Jhon": "smith",
		},
	}
	ctx := context.Background()

	// 1. Bind bind data to the file
	binder, _ := objectbind.Bind(ctx, &defaultConfig, "conf/test.yaml")

	// 2. BindField receive data change when Name filed is change
	binder.BindField("Name", func(value, _ interface{}) {
		fmt.Println("GET Data", value.(map[string]interface{}))
	})

	// change the data
	defaultConfig.Name["hello"] = "world"

	// 3. Save save the config changes  to remote
	_ = binder.Save(ctx)
}
