How can I utilize the mapv tool created by Baidu in a Node project?

I need assistance converting the following code to a node environment.

The code can be found at

Here is the code snippet:

    var map = new BMap.Map(slice.selector, {
        enableMapClick: false
    });    // Create Map instance
    map.centerAndZoom(new BMap.Point(105.403119, 38.028658), 5);  // Initialize map, set center coordinates and zoom level
    map.enableScrollWheelZoom(true); // Enable mouse scroll wheel zoom

    map.setMapStyle({
        style: 'light'
    });

    var randomCount = 300;

    var data = [];

    var citys = 
    ["北京","天津","上海","重庆","石家庄","太原","呼和浩特","哈尔滨",
     "长春","沈阳","济南","南京","合肥","杭州","南昌","福州","郑州","武汉",
     "长沙","广州","南宁","西安","银川","兰州","西宁","乌鲁木齐","成都",
     "贵阳","昆明","拉萨","海口"];

    // Generate data
    while (randomCount--) {
        var cityCenter = mapv.utilCityCenter.getCenterByCityName(citys[parseInt(Math.random() * citys.length)]);
        data.push({
            geometry: {
                type: 'Point',
                coordinates: [cityCenter.lng - 2 + Math.random() * 4, cityCenter.lat - 2 + Math.random() * 4]
            },
            count: 30 * Math.random()
        });
    }
    // Data set
    var dataSet = new mapv.DataSet(data);

    var options = {
        fillStyle: 'rgba(255, 50, 50, 0.6)',
        shadowColor: 'rgba(255, 50, 50, 1)',
        shadowBlur: 30,
        globalCompositeOperation: 'lighter',
        methods: {
            click: function (item) {
                console.log(item);
            }
        },
        size: 5,
        draw: 'simple'
    }

    var mapvLayer = new mapv.baiduMapLayer(map, dataSet, options);

I tried using "mapv = require('mapv');" to import the mapv module. However, I am unable to access the "BMap" module. Can you provide guidance on how to access it?

Insert the following code snippet into your index.html file and remember to utilize var BMap = window.BMap in your Javascript code.
