Create an application with ReactJS as front end and nodejs as backend. Application should have a csv file upload mechanism in a pop up. Popup will have 3 sections. One section for drag and drop the file, one section for file upload through a browse button, one section to upload file from a url (using password for url access if required).
Multiple file upload should be possible. It means when one file is being uploaded, user can start uploading other file.
If user close the pop up and navigate to other pages, file upload should give user a confirmation dialog reminding him about file upload in progress.
User can also upload zipped file. Application should unzip and upload csv file.
Size of csv file can be huge. Test with csv files with more than 100,000 rows and 50 columns. Test with csv files with size of more than 100 MB.
Application (or browser) should not hang for big files.
