## Installation

We recommend using this SDK as part of the overall [`@vonage/server-sdk` package](https://github.com/vonage/vonage-node-sdk). Please see the main package for installation.

You can also use this SDK standalone if you only need access to just the Voice API.

### With NPM

```bash
npm install @vonage/voice
```

### With Yarn

```bash
yarn add @vonage/voice
```

## Usage

### As part of the Vonage Server SDK

If you are using this SDK as part of the Vonage Server SDK, you can access it as the `voice` property off of the client that you instantiate.

```js
const { Vonage } = require('@vonage/server-sdk');

const credentials = {
  applicationId: APP_ID,
  privateKey: PRIVATE_KEY_PATH,
};
const options = {};
const vonage = new Vonage(credentials, options);

vonage.voice.getCall(CALL_UUID)
  .then(resp => console.log(resp))
  .catch(err => console.error(err));
```

### Standalone

The SDK can be used standalone from the main [Vonage Server SDK for Node.js](https://github.com/vonage/vonage-node-sdk) if you only need to use the Voice API. All you need to do is `require('@vonage/voice')`, and use the returned object to create your own client.

```js
const { Auth } = require('@vonage/auth');
const { Voice } = require('@vonage/voice');

const credentials = new Auth({
  applicationId: APP_ID,
  privateKey: PRIVATE_KEY_PATH,
});
const options = {};
const voiceClient = new Voice(credentials, options);
```

Where `credentials` is any option from [`@vonage/auth`](https://github.com/Vonage/vonage-node-sdk/blob/3.x/packages/auth/README.md#options), and `options` is any option from [`@vonage/server-client`](https://github.com/Vonage/vonage-node-sdk/blob/3.x/packages/server-client/README.md#options)

## Promises

Most methods that interact with the Vonage API uses Promises. You can either resolve these yourself, or use `await` to wait for a response.

```js
const resp = await vonage.voice.getCall(CALL_UUID)

vonage.voice.getCall(CALL_UUID)
 .then(resp => console.log(resp))
 .catch(err => console.error(err));
```

## Testing

Run:

```bash
npm run test
```
