Elf is a reactive immutable state management solution built on top of RxJS. It uses custom RxJS operators to query the state and pure functions to update it.

Elf encourages simplicity. It saves you the hassle of creating boilerplate code and offers powerful tools with a moderate learning curve, suitable for experienced and inexperienced developers alike.

 Modular by design
 Tree Shakeable & Fully Typed
 CLI
