Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@gravito/stasis 🧊

Gravito 的高效能快取與狀態管理 Orbit。

@gravito/stasis 將複雜的快取邏輯封裝成優雅且強大的 API,讓你的應用在處理高併發與海量數據時依然游刃有餘。


📖 快速索引


🌟 核心能力

  • 🚀 統一 API:無縫切換 Memory, Redis, File 等不同存儲驅動。
  • 🏗️ 混合快取 (Tiered):結合本地 Memory 與分散式 Redis,實現極限讀取速度。
  • 🔒 分散式鎖:基於原子操作的跨實例並發控制。
  • 🚦 流量節流:內建基於快取基礎設施的 Rate Limiting。
  • 🧠 智慧預熱:基於馬可夫鏈的存取路徑預測與自動讀取。

📦 安裝

bun add @gravito/stasis

🚀 5 分鐘快速上手

1. 配置 Orbit

import { defineConfig } from '@gravito/core'
import { OrbitStasis } from '@gravito/stasis'

export default defineConfig({
  config: {
    cache: {
      default: 'tiered', // 預設使用分層快取
      stores: {
        local: { driver: 'memory', maxItems: 1000 },
        remote: { driver: 'redis', connection: 'default' },
        tiered: { driver: 'tiered', local: 'local', remote: 'remote' }
      }
    }
  },
  orbits: [new OrbitStasis()]
})

2. 資料存取範例

const cache = core.container.make('cache');

// 💡 經典的「讀取或存儲」模式
const news = await cache.remember('news:today', 3600, () => {
  return await db.news.latest();
});
