I've not used lightstreamer before, but based on their documentation it looks like it's a way of fetching data real time as a subscription.

I've implemented it here as a starting point that you can use, see the following plunkr

Note that all I've done here is added the logic from the npm page inside the Grid Event onGridReady:

  onGridReady(params: GridReadyEvent) {
    var sub = new Subscription(
      'MERGE',
      ['item1', 'item2', 'item3'],
      ['stock_name', 'last_price']
    );
    sub.setDataAdapter('QUOTE_ADAPTER');
    sub.setRequestedSnapshot('yes');
    sub.addListener({
      onItemUpdate: (obj) => {
        const stockName = obj.getValue('stock_name');
        const lastPrice = obj.getValue('last_price');
        const newData = [
          ...this.rowData,
          { stock_name: stockName, last_price: lastPrice },
        ];
        this.rowData = newData;
      },
    });
    var client = new LightstreamerClient(
      'http://push.lightstreamer.com',
      'DEMO'
    );
    client.connect();
    client.subscribe(sub);
  }
