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 🙏

cerberus

react-native微应用/微组件纯JS解决方案

Usage

  • 安装cerberus-cli

    $ npm i -g @m860/cerberus-cli
  • 添加cerberus-cli配置文件 配置参数

    $ touch cbs.json
  • 启动本地服务

    $ npx cbs start cbs.json
  • 安装cerberus

    $ npm i @m860/cerberus
  • 使用useCerberus加载

    import * as React from "react"
    import {useCerberus} from "@m860/cerberus"
    
    export default function(){
        const [status,defined]=useCerberus({
            entry:"http://localhost:9000/main.js"
        });
        if(defined){
            const {default:App}=defined;
            return <App/>
        }
        return null;
    }

NOTE: 目前只支持hooks

Full Example

cli配置参数说明

type ConfigOption={
    // 同webpack.mode
    mode:string,
    // 同webpack.entry
    entry:any,
    // 同webpack.output
    output:any,
    /**
    * 需要替换的module
    * 
    * @example
    * {
    *     cerberusTransformOption:{
    *         modules:["dateformat"]
    *     }
    * }
    * 
    */
    cerberusTransformOption:{
        modules:Array<string>,
        /**
         * 需要处理的资源文件的正则表达式,默认:/\.(gif|png|jpeg|jpg|svg)$/i 
         */
        resourceTest?:?RegExp
    }
}

最佳实践

  • 一级页面不要使用cerberus来管理组件
  • 预加载组件,在APP启动的时候进行一次预加载。

自定义cloud访问的client

// 在App中使用CerberusContextProvider来自定义client
import * as React from "react"
import {CerberusContextProvider} from "@m860/cerberus"

export default function (){
    return (
        <CerberusContextProvider value={{
            client:{
                uri:"http://xxx"
            }
        }}>
        </CerberusContextProvider>
    );
}

Troubleshoot

  • 图片没有显示出来

    cli在编译的时候将本地引用的图片编译为uri的方式,所以必须设置width和height才能够正常显示

    <Image source={require("image.png")} style={{width:100,height:100}}/>
  • debug模式下缓存不生效

  • queryEntry参数的urls的顺序和配置文件中的顺序可能不一致,不要使用如下方式:(urls)=>urls[2]
