Hi,
I am using exceljs in a html environment. I wanted to use addImage.
But as soon as i do that i get an exception.

i used the following code:

// add image to workbook by filename
			var imageId1 = workbook.addImage({
			  filename: 'img/logo.jpeg',
			  extension: 'jpeg',
			});

i am using the following require.js definitions
`
//Set the path to jQuery to local path
requirejs.config({
paths: {
jquery: 'js/jquery',
Excel: "js/exceljs_2017_07_16",
//Excel: "js/exceljs",
fs: "js/filesaver.min", // enables download of files within javascript - is used from exceljs
jszip: "js/jszip.min", // jszip is used to generate zip files - is used from exceljs
lodash: "js/lodash", // jszip is used to generate zip files - is used from exceljs
es6shim: "js/es6-shim" // jszip is used to generate zip files - is used from exceljs
}
});

require(['Excel', 'fs', 'jszip', 'lodash', 'es6shim', 'jquery' ], function (Excel, fileSaver) {
...
}
i get the message that fs.readFile is not a function
TypeError: fs.readFile is not a function

`

The following code inside of exceljs (line 10749) is used (with a reference to fs.
function fsReadFileAsync(filename, options) { return new PromishLib.Promish(function (resolve, reject) { fs.readFile(filename, options, function (error, data) { if (error) { reject(error); } else { resolve(data); } }); }); }

What is the way to attach fs = What library do i have to include ? i am sure i can't include node.js :)
Thanks and best regards
Manfred
