wtf is flummox-immstruct-store?

This repository provides a specialized storage system for applications built with Flummox, a JavaScript framework for managing application state. Think of it as a filing cabinet that keeps track of all your app's data, user information, settings, page content, and anything else the app needs to remember. What makes this particular filing cabinet special is how it stores and updates data. Instead of directly changing information in place, it uses something called immutable structures (via a library called Immstruct). This means whenever data changes, the system creates a new version rather than modifying the old one. This approach makes it easier to track what changed, undo changes if needed, and prevent bugs that come from unexpected modifications. The "functional lens" part means the system provides focused views into your data, imagine being able to look at just the "user preferences" section without worrying about the entire cabinet's contents. Developers building Flummox applications would use this when they want a clean, predictable way to manage their app's global state. For example, if you're building an e-commerce app, you might use this to store the shopping cart, product listings, and logged-in user details. When a customer adds an item to their cart, the system records that change in a way that's trackable and reversible. It's particularly useful if you're worried about bugs from data being changed in unexpected ways, or if you want your app's behavior to be easy to understand and test. The README is quite brief and doesn't provide detailed setup instructions or examples, so you'd likely need to look at the actual code or documentation in the repository to understand exactly how to integrate it into a Flummox project.
