EasySAM

EasySAM is a minimal RxJS-powered library for implementing the SAM pattern in TypeScript and JavaScript applications.

SAM stands for:

• State
• Action
• Model

The goal is to keep state management predictable by separating:

• actions that express intent
• model logic that updates state
• state logic that decides what should happen next
• views that react to state changes

EasySAM uses RxJS to make state observation simple and composable.

Why EasySAM?

EasySAM gives you a lightweight way to build reactive state models without introducing a large framework.

It is useful when you want:

• explicit action-driven state transitions
• controlled mutations
• reactive subscriptions to the whole model or individual properties
• support for async actions
• a SAM-style feedback loop through state logic
