#Index.js Simple Example File

var nichxlsx = require('nich-xlsx');
var path = require('path');

// Additional options for package
// @param {boolean} devMode [enable or disable developer mode,
//   default value - false]
// @param {boolean} disableFinishConsoleLog [on/of console log after writing file
//   default value - false]
// @param {boolean} autoAddExtension [autoAdding '.xlsx' extension
//   default value - false]

var options = {
  // devMode: true,
  // disableFinishConsoleLog: true,
  autoAddExtension: true,
}

// init class for xlsx files
var folder = new nichxlsx.default(options); // passing options to the xlsx class

// init data for file
var filePath = path.join(__dirname, 'folderName'); // add file in folder 'folderName'
var fileName = 'testName'; // fileName without '.xlsx' extension
var workSheetName = 'sheetName'; // name for sheet name in Excel
var mainData = [['d11','d12','d13'],['d21','d22','d23'],['d31','f32','f33']]; // main data
var headerData = ['header 1', 'header 2', 'header 3']; // headers for main data columns

try {
  // passing data for the file
  folder.setFilePath(filePath);
  folder.setFileName(fileName);
  folder.setWorkSheetName(workSheetName);
  folder.setMainData(mainData);
  folder.setHeaderData(headerData);

  // make new xlsx file
  folder.makeFile();

  // clear all data
  folder.clearAllData();

  // passing almost the same data
  folder.setFileName(fileName + 'SecondFile'); // change file name for next file
  folder.setFilePath(filePath);
  folder.setMainData(mainData); // only mainData without headerData

  // make another xlsx file
  folder.makeFile();
} catch (error) {
  console.log('Throw ERROR!' + error.name + ' | ' + error.message);
}

If you have Errors like this: #Error: Cannot resolve module 'fs' so you need to modify your webpack config file:

...
target: 'node',
node: {
	fs: "empty",
	__dirname: false,
}
...

If you have problem with jszip or mkdirp, then you need also add these lines:

...
externals: [
	{
		'./jszip': 'jszip',
		'./cptable': 'var cptable',
		'Mkdirp': 'mkdirp',
		'Xlsx': 'xlsx'
	}
]
...
