# Remote Config

Remote Config is a feature that allows you to replace values or properties managed in your application with parameter values defined in the Hackle Dashboard, enabling real-time control of application behavior and configuration.

Navigate to the Remote Config screen in the Hackle Dashboard to configure parameter information and set values based on user identification rules.

## remoteConfig

Calling the `RemoteConfig()` method returns a `hackle.RemoteConfig` instance that holds the Remote Config information for the user (configured parameters and rule information).\
`RemoteConfig()` receives User Identifier information to match user properties against Remote Config rule information.\
You can access the desired parameter and receive its value through the methods provided by `hackle.RemoteConfig`.

```go
import "github.com/hackle-io/hackle-go-sdk/hackle"


//사용자 객체 - 사용자 식별자와 속성 가이드 참조
user := hackle.NewUserBuilder().ID("ae2182e0").Build()

// 원격 구성 정보 담은 인스턴스를 반환합니다.
remoteConfig := hackleClient.RemoteConfig(user)
```

## Remote Config Parameter Lookup

* Since parameter values configured on the Hackle Remote Config screen exist as key-value pairs, you can use the methods below according to the configured parameter type to receive the configured parameter value.

{% hint style="warning" %}
Remove Remote Config-related code after archiving.

Once a Remote Config parameter is archived, you can no longer access the parameter information. Therefore, after archiving a Remote Config parameter, be sure to clean up any related code.
{% endhint %}

### GetString

* Returns parameter values configured as STRING or JSON type.
* Returns the default value or the value configured in the rule, depending on the state decision.

```go
import "github.com/hackle-io/hackle-go-sdk/hackle"

//사용자 객체 - 사용자 식별자와 속성 가이드 참조
user := hackle.NewUserBuilder().ID("ae2182e0").Build()

// 원격 구성 정보 담은 인스턴스를 반환합니다.
remoteConfig := hackleClient.RemoteConfig(user)

stringValue := remoteConfig.GetString("string_key", "default_value")

//JSON Type
jsonValue := remoteConfig.GetString("json_key", "{}")
```

### GetNumber

* Returns the parameter value configured as Number type as a float64 type.
* Returns the default value or the value configured in the rule, depending on the state decision.

```go
import "github.com/hackle-io/hackle-go-sdk/hackle"

//사용자 객체 - 사용자 식별자와 속성 가이드 참조
user := hackle.NewUserBuilder().ID("ae2182e0").Build()

// 원격 구성 정보 담은 인스턴스를 반환합니다.
remoteConfig := hackleClient.RemoteConfig(user)

numberValue := remoteConfig.GetNumber("number_key", 42.0)
```

### GetBool

* Returns parameter values configured as Boolean type.
* Returns the default value or the value configured in the rule, depending on the state decision.

```go
import "github.com/hackle-io/hackle-go-sdk/hackle"

//사용자 객체 - 사용자 식별자와 속성 가이드 참조
user := hackle.NewUserBuilder().ID("ae2182e0").Build()

// 원격 구성 정보 담은 인스턴스를 반환합니다.
remoteConfig := hackleClient.RemoteConfig(user)

boolValue := hackleClient.GetBool("bool_key", false)
```
