# isMinVersionSupported

> 함수형 API `isMinVersionSupported`로도 같은 기능을 쓸 수 있어요.

### 기능 설명

현재 토스 앱 버전이 플랫폼별 최소 지원 버전 이상인지 확인해요. 현재 플랫폼(Android/iOS)에 해당하는 버전 기준으로 비교해요.

* `'always'`를 지정하면 해당 플랫폼에서 항상 `true`를 반환해요.
* `'never'`를 지정하면 해당 플랫폼에서 항상 `false`를 반환해요.
* 샌드박스 환경에서는 버전과 무관하게 항상 `true`를 반환해요.

### 타입

```ts
isMinVersionSupported(minVersions): boolean;
```

**Params**

```ts
{
  android: `${number}.${number}.${number}` | "always" | "never";
  ios: `${number}.${number}.${number}` | "always" | "never";
}
```

**Response**

`boolean`이에요.

### 예시 코드

```js
import { Environment } from "@apps-in-toss/web-framework";

const supported = Environment.isMinVersionSupported({
  android: "5.250.0",
  ios: "always",
});

if (!supported) {
  console.warn("현재 토스앱 버전에서는 이 기능을 사용할 수 없어요.");
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developers-apps-in-toss.toss.im/documentation/sdk/domains-api/environment/isminversionsupported.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
