I recently started migrating my NixOS configuration repository to follow the dendritic pattern.
This is a pattern where each Nix file is its own separate standalone module.
This makes it easier to refactor and re-organise files, and allows modules to be broken into multiple files.
Rather than rewrite everything at once, I decided to take an iterative approach.
This meant refactoring modules in-place within my existing configuration, and keeping everything in a working state.
I've migrated a number of modules, and will continue working through the remaining ones as time allows.
Once I've refactored everything, I'll go through them again and see what else I can do, like splitting modules into separate smaller files.
In general, the modules I've migrated have been smaller than what I had before, partly because there's less boilerplate code needed.
And, whilst there are more files, they are smaller than before, have a single responsibility and have less indentation than before - making them easier to read and understand.
