Architecture

[dotherightthing]

This project us based on the krm project:

• that project is not used as a library except for unit testing
• a global variable is directly assigned to the app config
• other global variables are directly assigned to class instances
• all of these globals can be referenced anywhere

This project differs in the following ways:

• the project can be used as a library
• presumably the library loads, and then the host project runs its code
• so the host project can't set globals for use by the library
• and it would be intimidating and error prone to expect non-devs to do the instantiation inside the host project
• so the app config is passed into the app and this is the only way the app can see it
• so therefore the class instances would also need to be passed in
• or global settings managed in a different way, e.g. script/document properties
• currently this is resolved by instantiating required classes inside constructors
• configuring them with the config object passed to the constructor

Refactored to use singletons as per https://github.com/dotherightthing/gsheet-compost-collections/
