Large File Upload In Flask

I am attempting to implement a flask application for uploading files. This file could be very large. For example, almost 2G in size. I have finished the server side process functio

Solution 1:

This will be a difficult task for your to figure out on your own. I would suggest a plugin like https://blueimp.github.io/jQuery-File-Upload/

You can see from this projects source code they use a method name which essentially looks at how large the file is and how much data has been transferred thus far and how much remains to show a percentage complete div.

code example from this project

progressall: function (e, data) {
                var $this = $(this);
                $this.find('.fileupload-progress')
                    .find('.progress').progressbar(
                        'option',
                        'value',
                        parseInt(data.loaded / data.total * 100, 10)
                    ).end()
                    .find('.progress-extended').each(function () {
                        $(this).html(
                            ($this.data('blueimp-fileupload') ||
                                    $this.data('fileupload'))
                                ._renderExtendedProgress(data)
                        );
                    });
            }

So if you do want to come up with your own solution, I would suggest you start by building a UI div rectangle which has a dynamic width which updates according to your percentage calculation based upon the file upload size and data uploaded... or just go with an already established solution.
