react-elmish-example

This is a learning project that explores how to organize React code using ideas from Elm, a programming language known for having a really clean way to manage application state and updates.

The core idea is simple: instead of each component managing its own state independently (which can get messy as apps grow), you put all the state at the top level and pass it down. When something needs to change, components send "actions" upward that describe what happened, and a single function processes those actions and updates the state. It's like having one source of truth for your entire app. The example demonstrates this with a counter component, and then shows how you can build more complex features on top—like a list of counters, keeping a log of every action that happened, and even undo/redo functionality.

The author built this to understand Elm's architecture better and to figure out how well those ideas work when applied to React. It's not a library or tool meant for production—it's a personal exploration with one concrete example included. You can run it locally by cloning the repository and starting a development server, or just visit the live version hosted on GitHub Pages.

This would appeal to React developers who've heard about Elm or Redux (which borrowed from Elm's ideas) and want to see a minimal, hands-on example of the pattern in action. It's useful if you're curious about state management patterns but don't want to dive into a big framework—you can see the bare-bones idea with just a few components. The ability to track every action and implement undo/redo as a side effect of this architecture is a nice demonstration of why developers find this pattern appealing.
