✨ Features

• Atomic Pulse Engine: Unified API supporting swr, cache-first, network-first and no-cache strategies with a single function call.
• Visual Diagnostics: Real-time DevTools to track TTL, Registry Hits, and Deduplication events as they happen.
• Event Bridge: Reactive synchronization ensuring that when data updates in one component, the entire UI stays in sync.
• App Router Native: Deeply optimized for Next.js Server Components, Actions, and high-performance client hydration.

⚠️ Beta Version Notice

This project is currently in v1.0.0-beta. We are actively refining the Registry Pulse logic and synchronization performance.

• Please report any bugs via GitHub Issues.
• Expect breaking changes until version 1.2.0.

📦 Installation

npm add @pixel-pulse/cache-brain-vue

🚀 Setup

Vue 3 (Vite/Plugin)

Initialize the client and install it as a plugin in your main.ts.

import { createApp } from 'vue';
import { CacheBrainClient } from '@pixel-pulse/cache-brain';
import { createCacheBrain } from '@pixel-pulse/cache-brain-vue';

const app = createApp(App);
const client = new CacheBrainClient({ defaultTTL: 300000 });

app.use(createCacheBrain(client));
app.mount('#app');

🎣 Usage

useSmartCache

The primary composable for fetching data. Returns fully reactive Refs.

<script setup lang="ts">
import { useSmartCache } from '@pixel-pulse/cache-brain-vue';

const { data, isLoading, refresh } = useSmartCache(
  ['profile', 'settings'],
  async () => {
    const res = await fetch('/api/settings');
    return res.json();
  }
);
</script>

<template>
  <div v-if="isLoading">Loading...</div>
  <div v-else-if="data">
    <h1>{{ data.userName }}</h1>
    <button @click="refresh()">Sync Settings</button>
  </div>
</template>

⚙️ Hook Options (SmartCacheOptions)

The useSmartCache composable returns a reactive object. Because it uses Vue's Reactivity API, you should access these properties using .value in scripts or directly in templates.

| Property | Type | Description | | :----------- | :---------------------- | :------------------------------------------------------------------------------------------- | | data | ShallowRef<T \| null> | The retrieved data. Uses shallowRef to prevent deep reactivity overhead on large datasets. | | isLoading | Ref<boolean> | true only during the initial fetch. Stays false during subsequent background refreshes. | | isFetching | Ref<boolean> | true whenever a network request is active, including background revalidations. | | error | Ref<Error \| null> | Captured error object if the fetcher function fails. | | refresh | Function | A manual trigger to force a fresh fetch. Accepts optional overrides for ttl or strategy. |
