# getSubscriptionData(
      subscribable: Subscribable<any>
): Promise<any>

Async function that only returns the first data result of a [Subscription](https://rxjs-dev.firebaseapp.com/api/index/class/Subscription) 

(to a [Subscribable](https://rxjs-dev.firebaseapp.com/api/index/interface/Subscribable))  

and then unsubscribes automatically.  Useful if you only want the first result and don't  

need to keep the Subscription open.

## Examples

```js

async function logToConsole() {

    let data = await getSubscriptionData(

        sendHTTPRequest('http://website.com') // returns an observable

    );

    console.log(data);

}

async function getFirstLottoNumber() {

    return await getSubscriptionData(lottoNumbersObservable);

}

```

## Installation

`npm i  @writetome51/get-subscription-data`

## Loading

```js

import {getSubscriptionData} from '@writetome51/get-subscription-data';

```
