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 🙏

Signature

简单签名认证,默认采用hmac-sha256加密,应对大多数场景足够用了

Install

npm i @4a/sign

Usage

const Sign = require('@4a/sign')
const sign = new Sign({ appId, appSecret })

创建签名

params = sign.append(params)

// Or
params.sign = sign.create(params)

验证签名

sign.verify(params) // 此时params包含sign

Options 实例化参数

appId: test
appSecret: test

# 可选参数
debug: false # 调试模式,显示调试日志
redis: new Redis() # ioredis实例,允许为空,为空则verify方法不验证once字段
timeout: 300 # 单位分,默认5分钟

公共签名参数

请求参数字段应避免与签名参数字段冲突

# 商户id
appId


# 一次性随机字符串
# 推荐为空,为空时自动生成,大多数场景无须主动设置
# options.redis参数存在时会验证该参数,有效防止重放攻击
once


# 签名时间戳
# 用于验证签名是否过期,默认5分钟
# 推荐为空,为空时自动生成,大多数场景无须主动设置
timestamp
