easy-model: model-first state with IoC and deep watching

TL;DR Class-based models: fields are state, methods are logic. Hooks-first API: useModel , useInstance , useWatcher . Deep watching and DI are built in. Instance caching by args makes state partitioning natural. Why it exists Most state libraries start with a store. easy-model starts with a model class . That shift makes domain logic cohesive and testable. You describe business behavior once, then subscribe to it in React with minimal glue. A minimal example import { useModel , useWatcher } from " easy-model " ; class CounterModel { count = 0 ; label : string ; constructor ( initial = 0 , label = " Counter " ) { this . count = initial ; this . label = label ; } increment () { this . count += 1 ; } decrement () { this . count -= 1 ; } } function Counter () { const counter = useModel ( CounterModel , [ 0 , " Demo " ]); useWatcher ( counter , ( keys , prev , next ) => { console . log ( " changed: " , keys . join ( " . " ), prev , " -> " , next ); }); return ( < div > < h2 > { counter . la
