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

安装

# npm
npm i lru-cache-api-notice
# pnpm
pnpm add lru-cache-api-notice

使用

// 在 main.js 中引入并设定参数
import { createLruCache, default as LruCache } from 'lru-cache-api-notice'
const options = {
	// 缓存时长, 单位:s
	cacheTime: 10,
	// 最大缓存数量
	maxCache: 20,
	// 启用本地存储,正式环境不推荐
	storage: localStorage || false,
	// 禁用缓存名单
	blackList: [],
	// 启用 api 通知功能
	useNotice: true
}
// 方式一
const lruCache = new LruCache(options)
// 方式二,单例
const lruCache = createLruCache(options)
// 修改参数
lruCache.setCacheTime(20)



// http.js 中引入
import { createLruCache } from 'lru-cache-api-notice'
const lruCache = createLruCache()

// request
const getCacheData = lruCache.get(key/* 根据请求接口生成的唯一 key */) ?? null
if (getCacheData !== null) {
	// 命中缓存
	return getCacheData
}

// response
lruCache.set(key, value)

lruCache

  • 使用 lruCache 后,所有请求结果均会被缓存(建议只对 get 请求做缓存处理)。如果缓存存在且在缓存有效期内,所有请求均不会发送(需自行处理)
  • 使用 useNotice 后,相同 key 的请求只会发送一次,其余请求会在第一个请求结果返回后,进行通知(失败时需自行调用 noticeReject)
// main.js

lruCache.setUseNotice(true)
function getData() {
	http.get('url')	
}
getData()
getData()
getData()
// response
if (lruCache.useNotice && responseFail) {
	lruCache.noticeReject(key)
}
