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 🙏

a cache controller for cache data from request, can be auto read when a request have finished. and auto remove the least use cache.

Features

缓存控制插件 用于和请求混合使用以达到缓存请求的作用

Example

// axios.js

import CacheController from 'cachecontroller'
const requestCacheController = new CacheController({ maxSize: 50, maxUseTime: 3 })


// 创建axios实例
const service = axios.create({
    baseURL: '/api',
    timeout: 15000
})


const request = async (config) =>{
    //  可自行实现
        const generateDataStr = config => {
            const { method, data, params } = config
            let dataStr = ''
            if (method === 'get' && params) {
                dataStr = typeof params !== 'string' ? JSON.stringify(params) : params
            }
            if (method === 'post' && data) {
                dataStr = typeof data !== 'string' ? JSON.stringify(data) : data
            }
            return dataStr
        }
        const dataStr = generateDataStr(config)
        const hash = `${method}${url}${dataStr}${unique ? Math.random() : ''}`
        return new Promise((resolve, reject) => { 
        if (requestCacheController.haveCache(hash)) {
            return resolve(requestCacheController.getCache(hash))   
            }else{
            const data = await service.request(config)
            if(config.cache){
                requestCacheController.setCache(hash, { data, size: 1 })
            }
            return data
        }
    })
}

// api.js

import request from 'axios.js'

export function addAddress (params) {
    return request({
        url:'/address',
        params,
        cache:true
    })
}

params 实例参数说明

| 参数 | 默认值 | 说明 | 类型| | ---- | ---- |----|----| | maxSize|10 |储存的数据大小当装满了会尝试清空最早使用的数据腾出空间 | number | | maxUseTime | 3 | 最大使用次数,当从缓存中读取次数超过该数字缓存将被移除。| number

methods 方法说明

| 方法名 | 参数 | 说明 | 返回值 | | ---- | ----- |----|----| | setCache | key:string, blob:{size:number,data:any} | 存入缓存,key值唯一,当重复出现会覆盖。bolb size 必传且必必须是数字 | void | | haveCache | key:sytring | 返回缓存中是否含有对应key的缓存不计入读取次数 | boolean | getCache | key:sytring | 返回缓存中有对应key的缓存 | (any or null) | removeEarliestCache | void | 删除最早使用的key对应的缓存 | void | deleteCache | key:string | 删除key对应的缓存 | void
