Kretes works best with the Nix package manager. This simplifies the management of the application dependencies. Nix not only makes the development environment easier to manage, but it also can substantially help organize dependencies when deploying to production.
Once Nix is installed, there will no longer be needed to install any dependencies manually, including things like setting up and configuring the database and its plugins. From now on everything needed by Kretes to run your application will be automatically installed and configured behind the scenes.
Note, that the installation of the first dependency in Nix can be a bit long, but afterwards it will be quick again.
