RedConf
=======
Sync config from redis or others storages while the key's value changed
#### Usage
- The following struct is the config what we want sync with storage while the values changed
```go
type ServerConfig struct {
Host string
Port int
AllowIPs []string
}
type LogConfig struct {
Path string
Maxsize int
}
type AppConfig struct {
Server ServerConfig
Log LogConfig
}
```
- We need create storage for tell redconf where the config values stored, and create monitor to notify the redconf while the values changed
```go
opts = redconf.Options{
"address": "localhost:6379",
"password": "",
"db": 0,
"idle": 10,
"channel": "ONCHANGED",
}
if monitor, err = redconf.CreateMonitor("redis", opts); err != nil {
fmt.Println(err)
return
}
if storage, err = redconf.CreateStorage("redis", opts); err != nil {
fmt.Println(err)
return
}
```
- Create RedConf instance and watch the config
```go
if redConf, err = redconf.New(namespace, storage, monitor); err != nil {
return
}
appConf := AppConfig{}
if err = redConf.Watch(&appConf); err != nil {
fmt.Println(err)
return
}
```
- Initial redis key-value
```bash
$> redis-cli
127.0.0.1:6379> SET GOGAP:AppConfig:Server:AllowIPs 127.0.0.1,202.10.5.123
OK
```
- Run example code
``` bash
$> go run example/*.go
```
- Open new terminal session and change the config in redis
```bash
$> redis-cli
127.0.0.1:6379>SET GOGAP:AppConfig:Server:AllowIPs 127.0.0.1,202.10.5.125
OK
127.0.0.1:6379> PUBLISH ONCHANGED GOGAP:AppConfig:Server:AllowIPs
(integer) 1
```
Then you will see the change from your terminal
- if you want subscribe the value change event, you could do as following:
```go
func onValueChangedSubscriber(event redconf.OnValueChangedEvent) {
var err error
var data []byte
if data, err = json.MarshalIndent(&event, "", " "); err != nil {
fmt.Println(err)
return
}
fmt.Println(string(data))
}
redConf.Subscribe(onValueChangedSubscriber)
```
