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 🙏

支持jsonrpc 协议调用,是对axios库的封装,支持动态切换访问地址来调用服务接口

install

yarn add axios log4js  xenon-jsonrpc-client -D

Usage

typescript:

import {JsonRpcClient} from "xenon-jsonrpc-client"
import {getLogger} from 'log4js'
const logger = getLogger("out")


try{
    const options={
        //服务名称
        serviceName:'xxx',
        //指定url地址,如果指定了该值,这不会走nacos的负载均衡器,直接调用url所指定的地址
        //url:'http://localhost:9501', 
        // 接口的path路径,默认值为"/"
        path:'v1', 
        // 当需要走nacos的负载均衡器时,需要写下面的代码,该代码是通过负载均衡器获得一个
        // 可访问的url地址
        getHost:(serviceName:string)=>{
            const instancesRobin=config.nacosInstances[serviceName]
            if(!instancesRobin){
                return null
            }
            const host=instancesRobin.pick()
            return host
        },
        // logger 日志输出, 如log4js
        logger:logger,
        // 全局配置变量,和nacos所使用的变量为同一个对象
        config:config 
    }

    // 声明对象,一个serviceName代表一个服务,如果有多个不同的服务,需要定义个多实例对象,
    // 每个实例对象只能访问自己的数据资源
    const jsonRpcClient=  new JsonRpcClient(options)

    //调用示例的参数
    var param = {
        "keyId": 'xxxxxx',
        "salt": '',
        "info": 'dddddddddddddddddddddddddddddddddddddddd',
        "length": 16
    }
    //调用请求方法
    //  第一个参数为 method
    //  第二个参数为 需要请求的params
    const res=await jsonRpcClient.request('xxxxxxx',param)
    
    //异步返回调用结果
    logger.info(JSON.stringify(res))
}catch (e){
    //输出异常信息
    logger.error(e) 
}
