Very basic express.js app to create a route that generates and downloads a basic Excel workbook

excel4node express.js example

var express = require('express');
var xl = require('excel4node');

var app = express();

app.get('/', function(req, res){
	res.end('Hello World');
});

app.get('/myreport', function(req, res) {
  makeReport(req, res);
});

var server = app.listen(3000, function () {
  console.log('Example app listening at http://%s:%s', '127.0.0.1', 3000);
});

function makeReport(req, res){
	var wb = new xl.WorkBook();
	var ws = wb.WorkSheet('Sheet1');

	ws.Cell(1,1).String('String');

	wb.write('MyWorkBook.xlsx', res);
}
