I am trying to minified highcharts.src.js using bundleconfig.json in asp.net core using BuildBundlerMinifier Package for that I have written the below code in bundleconfig.json

[
    {
        "outputFileName": "wwwroot/js/highchart2.min.js",
        "inputFiles": [
            "wwwroot/lib/highcharts/highcharts.src.js"
        ],
        "minify": {
            "enabled": true,
            "renameLocals": false
        }
    }
]
