About:
Lager is a C++ library that enables developers to build applications using a unidirectional data-flow architecture, inspired by Redux. It promotes value-oriented design, making state management predictable and testable. The library provides a framework for handling state updates and side effects in a structured manner.

Key Features:

Unidirectional data flow architecture
State management based on value semantics
Support for Redux-like reducers and effects
Integration with C++ standard library and Boost

Use Cases:

Building complex user interfaces with predictable state
Developing event-driven applications requiring robust state management
Implementing functional reactive programming patterns in C++

Alternatives:

Redux – JavaScript library with similar architecture, but Lager is designed specifically for C++ and value semantics.
Elm – Functional language for web apps, while Lager is a C++ library for native applications.
