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 🙏

以伪协议的形式配置你的请求

最简易用法

  1. 注册请求器
var fetcher = require('pigfarm-fetcher');
var request = require('request');

fetcher.registerRequestor('http', function(cfg) {
    return new Promise((rs, rj)=> {
        request(cfg.url, function(err, res) {
            err ? rj() : rs();
        })    
    })
});
  1. 通过配置创建请求
var requestIndex = fetcher.build({
    url: 'http://v.qq.com?ptag={ptag}'
})
  1. 执行请求
try {
    var result = await requestIndex({
        ptag: 'pigfarm'
    });
    console.log(result);
} catch(e) {
    console.error(e);
}

意义

将远程调用所涉及的上下游事务分为三层,分别适合负责解决团队疑难杂症的同学,开启业务项目的同学,以及后续维护业务的同学编写。

如此分层也适合在不同执行环境下进行facade模式。同一个协议,在不同的环境下注册不同的请求器,自然就可以无缝移植请求配置。
