Unable to start DXLinkWebSocketClient - WebSocket is not defined

sharanwj commented 1 month ago

Getting error when creating a client -

const client = new DXLinkWebSocketClient()
    client.connect('wss://openapi-ws.dxfeed.com/realtime')
    client.setAuthToken('xyz')

    const feed = new DXLinkFeed(client, FeedContract.AUTO)
    feed.configure({
        acceptAggregationPeriod: 10,
        acceptDataFormat: FeedDataFormat.COMPACT,
        acceptEventFields: {
            Quote: ['eventSymbol', 'askPrice', 'bidPrice'],
            Candle: ['eventSymbol', 'open', 'close', 'high', 'low', 'volume'],
        },
    })

Error - this.socket = new WebSocket(this.url) ^ ReferenceError: WebSocket is not defined at WebSocketConnector.start (file:///Users/xyz/tt/node_modules/@dxfeed/dxlink-websocket-client/src/connector.ts:23:23)

I added this import in connector class which fixed the issue locally for me - import WebSocket from 'ws';

Hi,

WebSocket should be available in your environment. If necessary, you can simply polyfill it.

Let me know if you need any further adjustments!

Closing due to lack of responses. You may reopen the issue if you need to.
