workbook.addWorkSheet is not a function

Below goes code I have written

'use strict';

const Hapi = require('hapi');
const Path = require('path');
var fs = require('fs');
var Excel = require('exceljs');

// create new server instance and connection information
const server = new Hapi.Server({  
    host: 'localhost',
    port: 5009
  })

//server.path(__dirname)

// Add the route
server.route({
    method: 'GET',
    path:'/path', 
    handler: function (request, h) {
        let file = 'test.xlsx';
        let filePath = Path.join(__dirname,file);
        return 'file path - '+filePath;
    }
});

server.route({
        method: 'GET',
        path: '/test.xlsx',
        handler: function (request, h) {
            let file = 'test.xlsx';
            let filePath = Path.join(__dirname,file)
            let contentType = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
            let data;
            console.log(filePath)
            fs.readFile(filePath, function(error, content) {
                data = content;
            });
            console.log(data);
            const res = h.response(data).type(contentType)
                .header('Content-Disposition', 'attachment; filename=' + file);
            
            console.log(res);
            return res;
        }
});
function createWorkBook(filePath) {
        console.log("Inside the function createWorkBook");
        var workbook = new Excel.Workbook();
        console.log(workbook);
        workbook.views = [
            {
              x: 0, y: 0, width: 10000, height: 20000,
              firstSheet: 0, activeTab: 1, visibility: 'visible'
            }
        ]
        var worksheet = workbook.addWorkSheet("Data",{properties:{tabColor:{argb:'FFC0000'}}});
       
        workbook.xlsx.writeFile(filePath)
                .then(function() {
                    console.log("File created successfully")
                });
}
        

// Start the server
async function start() {

    try {
        await server.start();
    }
    catch (err) {
        console.log(err);
        process.exit(1);
    }

    console.log('Server running at:', server.info.uri);
};

start();
createWorkBook(Path.join(__dirname,'data.xlsx'));

Below goes the error:

    var worksheet = workbook.addWorkSheet("Fund Data",{properties:{tabColor:{argb:'FFC0000'}}});
                             ^

Any help on this?

Can you please note how you solved it?

Update: While I haven’t tested it yet and am about to - I’m pretty confident I know what happened. In a nutshell: Operator error.

In a further summary: Lesson for today - when you are so used to Typescript catching the idiotic stuff instead of linting Javascript, quit being really get lazy and forgetting to check basic things. Such as:

1. Calling spliceRow instead of spliceRows.
2. Forgetting to put an await in calling an async function in one of the few lines of code that are different between constructing the first spreadsheet and the second one. So of course this fat finger was in the constructing the second one.

Bottom line: Never mind.
