reconnecting-ws

Wrap WS client to auto reconnect websocket server when disconnected by any reason.

The code is based on https://github.com/websockets/ws/wiki/Websocket-client-implementation-for-auto-reconnect

Installing

``
npm install --save reconnecting-ws
`

Using

`typescript
import { WebSocketClient } from 'reconnecting-ws';


class SocketClient {

private webSocketClient: WebSocketClient;
constructor() {
/**
* Init WebSocketClient
* Set trying reconnect when connection lost each 5 seconds, and show console message
*/
this.webSocketClient = new WebSocketClient(5000, true);

/* Subscribe to emitters. /
this.webSocketClient.on('open', this.onOpen);
this.webSocketClient.on('error', this.onError);
this.webSocketClient.on('message', this.onMessage);
this.webSocketClient.on('close', this.onClose);
this.webSocketClient.on('reconnect', this.onReconnect);

/* Connect to server. /
this.webSocketClient.connect('ws://127.0.0.1:3001');

/**
* Its possible to access WebSocket instance directly.
* without using wrapper of WebSocketClient. (see https://github.com/websockets/ws).
Note that when trying to reconnect all* listeners will be removed
*/
const bufferAmount = this.webSocketClient.WebSocketInstance.bufferedAmount;

/* Disconnect manually in minute. /
setTimeout(() => {
this.webSocketClient.disconnect();
}, 60000);
}
