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 🙏

Readme

cat-tool

面向浏览器应用的轻量 TypeScript 工具库,提供事件总线、并发队列、IndexedDB、页面水印、定位、UUID 和函数缓存等常用能力。

在线文档 · 变更记录

安装

npm install cat-tool

所有工具都支持具名导入和独立子路径导入,后者可进一步缩小打包体积:

import { PromiseQueue, getLocation, memoize, uuid } from 'cat-tool';
// 或:import { PromiseQueue } from 'cat-tool/promise-queue';

常用示例

const queue = new PromiseQueue(3);
const results = await Promise.all([
  queue.enqueue(() => fetch('/api/a').then((response) => response.json())),
  queue.enqueue(() => fetch('/api/b').then((response) => response.json())),
]);

const cached = memoize((id: string) => expensiveLookup(id), {
  max: 100,
  resolver: (id) => id,
});

const location = await getLocation({ timeout: 5000, maximumAge: 60_000 });
console.log(uuid.buildID(), location, results, cached('cat'));

浏览器能力(定位、IndexedDB 和水印)会在运行时检查环境,不支持时返回可捕获的 Promise 错误或明确异常。旧版拼写 getLocaltion 仍保留,但新代码请使用 getLocation
