Store

import { createStore } from '@sinuxjs/core';

const store = createStore(
  { count: 0, name: 'world' },  // initial state
  {                               // signal definitions
    increment: (state) => ({ count: state.count + 1 }),
    setName: (state, name: string) => ({ name }),
  }
);

store.getState();              // { count: 0, name: 'world' }
await store.increment();
store.getState();              // { count: 1, name: 'world' }
await store.setName('Sinux');
store.getState();              // { count: 1, name: 'Sinux' }

A store holds your application state. createStore(initialState, signals, middlewares?) is the factory function.

State updates are shallow merges ({...state, ...partial})
getState() returns a shallow copy (safe to read)
updateState(partial) only triggers subscribers if state actually changed (shallow equality)
subscribe(callback) returns an unsubscribe function
resetStore() restores initial state
