@reckona/mreact-reactive-core

@reckona/mreact-reactive-core provides the fine-grained reactive primitives used across mreact. It is independent from the DOM and can be used by stores, forms, query observers, and compiled runtime code.

Basic Usage

import { cell, computed, effect } from "@reckona/mreact-reactive-core";

const count = cell(0);
const doubled = computed(() => count.get() * 2);

const dispose = effect(() => {
  console.log(doubled.get());
});

count.set(1);
dispose();

Core APIs

• cell() creates a writable reactive value.
• computed() creates a derived readonly value.
• effect() runs side effects when dependencies change.
• batch() groups updates into one flush.
• untrack() reads values without subscribing.

Testing

@reckona/mreact-reactive-core/testing exports flushMicrotasks() and flushEffects() for deterministic tests.
