I wanted to download all of my submissions from HackerRank. Initially, I thought of using web scraping but then I thought may be HackerRank would have some API for that. Eventually, I found that a user can get a copy of its profile data which includes all of the code submissions as well. This was exactly what was required.

Then I wrote a simple script which gets the data from the profile data file(which is just a JSON file compressed in gzip format) and writes it in various files.

To create an executable for Windows, Linux and macOS, I have used

pkg

to build the binary from Node.js script.
