Managing state with Elf, a new reactive framework

Elf is a reactive and immutable state management library built on top of RxJS, designed to simplify the management of state in JavaScript applications by reducing the boilerplate code often associated with libraries like Redux. The library offers tools such as observables, observers, and subscriptions for managing state changes and allows developers to create stores that act like databases to hold application state. Elf stores are observables that can be subscribed to for real-time updates, and the library provides operators like select for accessing specific slices of state. Additionally, Elf supports the creation and manipulation of entities, which store large collections of data similarly to database tables, and offers query and mutation methods for interacting with these entities. The library also includes a persistState function, enabling developers to save parts of the application state to local or session storage using strategies like localStorageStrategy or sessionStorageStrategy. While Elf is noted for its low learning curve compared to other solutions, its documentation lacks comprehensive examples, making it potentially more suitable for personal or pet projects.
