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 🙏

Abtest

流量均衡AB实验分组策略

Install

npm i @4a/abtest

Usage

根据abtestIdid地址执行流量均衡分组

// abtest依赖redis
// redis实例需支持promise,推荐配合ioredis使用
import ABTest from '@4a/abtest'

// or
const ABTest = require('@4a/abtest').default.register(redis)

// async函数内调用
return await ABTest.grouping(testId, id) // Number

// 设置redis过期时间,默认7d
// 实验停止后,redis关联key 7天后过期
// 实验期间每次命中实验都会刷新有效期
return await ABTest.grouping(testId, id, 7 * 60 * 60)

Notes

# 
# 1、流量均衡分组
# 2、默认分组结果 a:1, b:2, c:0
# 3、根据id来进行固定分组
# 4、可同时进行多个实验,按照abtestId区分
# 
# 5、前端实验分组单步时长,过期时间前端可自行设置
# 
# c:0 C组表示意外分组流量,其他分组失败的流量也会归到C组
#

Example

npm test

DEBUG=abtest npm test
