Feedback please - Backend application to bookmark GitHub repository

The backend part has the following purposes.

  • An endpoint that takes a search term and returns a list of repositories.
  • An endpoint that allows bookmarking a repository by its id.
  • An endpoint to get all bookmarked repositories
  • An endpoint to remove a bookmark.

I have written the code for the application using NodeJS and Express. The application is working well. I would like to have a code review for code quality and suggestions for improvements.

Thanks in advance.
