Hi, well done! Your code is very concise, you could expand your database by adding tests and unit tests, that are a very important part of programming projects and widely supported in D. To get an example of possible test you can check this: https://github.com/damphat/kv-bash You can read about unittests in the D-Gems section https://tour.dlang.org/tour/en/gems/unittesting and the D wiki https://wiki.dlang.org/Unittest and also an article by Funkwerk https://dlang.org/blog/2017/10/20/unit-testing-in-action/ Also, it could be important to take care of error management in your program. What happens if the database stores an invalid json? What happens if I retrieve a key that is not in the database? You can read more about error handling and exceptions and scope guards here: https://tour.dlang.org/tour/en/basics/exceptions These are points that I hope can give you suggestion on how to further improve your code and abilities and hopefully continue learning D.
