Why should you care?

If you allow multiple large files upload then a progress indicator is a cool way to give user feedback.

Nowadays HTML5 File API based progress is the best way to achieve your goal.

How to build and run as plain js

$ git clone https://github.com/girish1729/progress.up
$ cd progress.up/backend
$ yarn install

Or

$ npm install

$ mkdir uploads

$ npm start

Now head to http://localhost:2324

to try uploading files.

The uploaded files are present in backend/uploads folder.

Backend

This backend is Node.js HTTP server express.js with multer middleware

This ensures that this code is platform agnostic. Most issues with file upload plugins extant today hover around not specifying backend correctly. Not making it easy to use. Not explaining what should be the input file name attribute etc.

We require a backend that accepts multipart/form-data as upload protocol.

Please also ensure the file names array in input field matches the backend configuration.

There is also a test upload feature to check if upload protocol works.
