Using sqlitedict in dash

Hello,

I would be happy to have some opinions on a small package that I released called “dash_database”. It is made for sharing data between callbacks and uses sqlitedict in place of (for instance) redis.

Link to the repository: https://github.com/ThibTrip/dash_database

It is pip installable (after git cloning) and I’d like to publish it to PyPI if there aren’t any flaws with it (security concerns for instance or performance issues etc.). I am also hosting a presentation on dash to 20+ people on Wednesday and one the apps I’ll show will include this package.

I have used it privately for a while and it works really really well but it was on a very small scale.

Thanks in advance!

Hello,

so I investigated on my own and decided to upload the package on PyPI after doing the following:

  • look at the source code in sqlitedict and check for vulnerable points
  • restrict the types to str or int for some arguments in the main class (DashDatase) methods (this is to prevent any bad surprises like a user id being None and multiple users accessing the same key as a consequence)
  • 100 % coverage and some tests to make sure it works as expected

I hope it will help some people and I’d still be happy to hear some feedback :slight_smile:

Is this just for multi-threading or does it work with multiple server workers? :slight_smile:
