## Overview  

This is a wrapper library over [OneSignal REST API](https://documentation.onesignal.com/reference). You can create notifications,
view apps, edit a device and all other actions you can take on OneSignal REST API.

## Installation      
      
```      
npm install onesignal-node --save      
```      

## Usage
      
``` js      
const OneSignal = require('onesignal-node');    
```      
OR
``` js      
import * as OneSignal from 'onesignal-node';  
```

### Client Types:

For all the actions that require your OneSignal app id and app api key, you should use `OneSignal.Client`.
Sample actions: create notification, add device, csv export, create segment...

``` js      
const client = new OneSignal.Client('appId', 'apiKey');
``` 

For all the actions that require your User Auth Key you should use `OneSignal.UserClient`.
Sample actions: view apps, update an app, create an app...

``` js      
const userClient = new OneSignal.UserClient('userAuthKey');
```      
      
### Creating client      

You can create a `Client` object as shown below. It requires two parameters: `appId` and `apiKey`, which you can find them on
your applications page on OneSignal dashboard.  

There is also an optional parameter called `options`. You can set OneSignal rest api endpoint if you wish to using options.
By default the library uses `https://onesignal.com/api/v1` for api endpoint.
  
```js      
// With default options
const client = new OneSignal.Client('appId', 'apiKey');

// With custom API endpoint
const client = new OneSignal.Client('appId', 'apiKey', { apiRoot: 'https://onesignal.com/api/v2'});
```      

### Creating UserClient      

You can create a `UserClient` object as shown below. It requires one parameter: `userAuthKey`, which you can find it on
your OneSignal dashboard.

There is also an optional parameter called `options`. You can set OneSignal rest api endpoint if you wish to using options.
By default the library uses `https://onesignal.com/api/v1` for api endpoint.
  
```js      
// With default options
const userClient = new OneSignal.UserClient('userAuthKey');

// With custom API endpoint
const userClient = new OneSignal.UserClient('userAuthKey', { apiRoot: 'https://onesignal.com/api/v2'});
```     

### Create notification      

https://documentation.onesignal.com/reference/create-notification 

```ts
.createNotification(body: CreateNotificationBody): Promise<ClientResponse>
```

Please read the sections above to learn how to create a `Client` object.

```js      
// See all fields: https://documentation.onesignal.com/reference/create-notification
const notification = {
  contents: {
    'tr': 'Yeni bildirim',
    'en': 'New notification',
  },
  included_segments: ['Subscribed Users'],
  filters: [
    { field: 'tag', key: 'level', relation: '>', value: 10 }
  ]
};

// using async/await
try {
  const response = await client.createNotification(notification);
  console.log(response.body.id);
} catch (e) {
  if (e instanceof OneSignal.HTTPError) {
    // When status code of HTTP response is not 2xx, HTTPError is thrown.
    console.log(e.statusCode);
    console.log(e.body);
  }
}

// or you can use promise style:
client.createNotification(notification)
  .then(response => {})
  .catch(e => {});
```      
    
### Cancel notification   

https://documentation.onesignal.com/reference/cancel-notification

console.log(response.headers);
console.log(response.statusCode);    
```

console.log(response.body);

// with query
const response = await client.viewNotifications({ limit:10, kind: 2, offset: 2 });
