Angular 5 app breaks when using XLSX to export table to .xlsx file in prod build.

I’m trying to use xlsx package for exporting files from table to .xlsx file. It works on normal build but breaks on prod build in Angular 5.

            let sheetName;
	var tbl = document.getElementById(this.activeTab);
		/* generate worksheet */
	let ws: XLSX.WorkSheet = XLSX.utils.table_to_sheet(tbl, {raw:true});

	ws['!cols'] = [
		{wpx: 200}, // "characters"
		{wpx: 200}, // "pixels"
		{wpx: 200},
		{hidden: true} // hide column
	];

		/* generate workbook and add the worksheet */
	const wb: XLSX.WorkBook = XLSX.utils.book_new();
	XLSX.utils.book_append_sheet(wb, ws, sheetName);

		/* save to file */
	XLSX.writeFile(wb, this.fileName, {type: "base64"});`

Thanks

What is the error message? Can you share a sample project?

Since this works with the standard new ng project setups, we can only assume the issue lies with how Angular or your specific projects work with the library in prod mode. This is unfortunately the type of issue that would require someone well-versed in Angular to diagnose.
