How to download created excel file in node js using exceljs

Question

I am using exceljs module for creating excel file. The problem is it is neither getting created nor getting saved in the path.

var excel = require('exceljs');
var options = {
    filename: './streamed-workbook.xlsx',
    useStyles: true,
    useSharedStrings: true
};

var workbook = new Excel.stream.xlsx.WorkbookWriter(options);
var sheet = workbook.addWorksheet('My Sheet');
worksheet.columns = [
    { header: 'Id', key: 'id', width: 10 },
    { header: 'Name', key: 'name', width: 32 },
    { header: 'D.O.B.', key: 'DOB', width: 10 }
];

worksheet.addRow({id: 1, name: 'John Doe', dob: new Date(1970,1,1)});
worksheet.addRow({id: 2, name: 'Jane Doe', dob: new Date(1965,1,7)});
worksheet.commit();

workbook.commit().then(function(){
    console.log('xls file is written.');
});

But when I run the code nothing happens. The excel is not created. What am I missing here?

*********************** Edit ************************** Made the following changes to my code but still its not working.

        var Excel = require('exceljs');
        var workbook = new Excel.Workbook();
        var worksheet = workbook.addWorksheet('My Sheet');
        worksheet.columns = [
            { header: 'Id', key: 'id', width: 10 },
            { header: 'Name', key: 'name', width: 32 },
            { header: 'D.O.B.', key: 'DOB', width: 10 }
        ];
        worksheet.addRow({id: 1, name: 'John Doe', dob: new Date(1970,1,1)});
        worksheet.addRow({id: 2, name: 'Jane Doe', dob: new Date(1965,1,7)});
        workbook.commit();
        workbook.xlsx.writeFile('./temp.xlsx').then(function() {
            // done
            console.log('file is written');
        });
