Ajax Large File Uploader

I create this project to upload a very large file. by splitting the file on client side and upload every part to the backend service which merge append every part to the file.

Setup on your project

The Project is not depend on any other library.

FrontEnd (HTML/JS)

1- Add script in html page

<script src="/fileuploader/fileuploader.js"></script>

2- create uploader Object to upload the file

 		
	    var file= document.getElementById("fileID").files[0];
	    var backendUrl = "/admin/upload"; // Backend Url that handle uploaded chuncks
	    var filePartSize = 100000; // the size of every chunck

	    var partUploadHandler = function(percent){
		// percent is a value between 0 to 100
                console.log("upload part = "+percent);
		// You can update progress bar if  you have with percent.
            };

	
	    var uploadCompleteHandler = function(result){
               alert("upload done! = "+JSON.stringify(result));
                $("#uploadsUrls").append("<p>url : "+result.url+"</p>")
            };

            var uploader = AjaxUploader.createUploader(backendUrl, filePartSize, partUploadHandler, uploadCompleteHandler);
            uploader.upload(file);

Backend

Note, In backend we append the data to the same file in every request. Please review the implementation in "Backend" folder for Java and Python.
