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 🙏

🚀 快速开始

npm run dev

访问 http://localhost:3000 开始使用应用。

🛠️ 技术栈

  • DuckDB-WASM - 在浏览器中运行的 SQL 数据库
  • React - 用户界面框架
  • Ant Design - UI 组件库
  • IndexedDB - 用于持久化存储数据
  • Web Workers - 用于在后台处理数据

SQL 示例

以下是一些实用的 SQL 查询示例:

-- 带限制的基本查询
SELECT * FROM "my_dataset" LIMIT 100;

-- 数据筛选
SELECT * FROM "my_dataset" WHERE column_name > 100;

-- 分组聚合
SELECT category, COUNT(*) as count, AVG(value) as average
FROM "my_dataset"
GROUP BY category
ORDER BY count DESC;

-- 多数据集连接
SELECT a.*, b.additional_column
FROM "dataset_a" a
JOIN "dataset_b" b ON a.id = b.id;

🔒 数据安全与隐私

  • 所有数据都存储在本地浏览器中
  • 不会上传数据到任何服务器
  • 数据持久化由浏览器的 IndexedDB 处理
  • 清除浏览器数据会导致存储的数据集丢失
