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.
