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 🙏

@bytesurging/pay-protocol

v0.1.0

Published

HMAC signing protocol for business-server → pay-central service calls

Readme

@bytesurging/pay-protocol

业务服 → pay-central 服务间 HMAC 签名算法(不含 app_secret)。

安全依赖密钥保密,不依赖算法保密。包内禁止放入真实生产密钥。

用法

import {
  buildPathWithQuery,
  buildServiceSignContent,
  computeServiceSignature,
  verifyServiceSignature,
  isTimestampWithinSkew,
} from "@bytesurging/pay-protocol";

待签串(\n 分隔):timestamp / METHOD / pathWithQuery / userId / sha256(rawBody)。

x-signature = HMAC_SHA256(appSecret, content).hex().lower()

时间窗默认 ±300 秒(PAY_SERVICE_SIGN_SKEW_SECONDS)。

本地联调

在消费方 package.json:

"@bytesurging/pay-protocol": "file:../../npm/packages/pay-protocol"

(路径按实际相对位置调整。)请先在本包执行 pnpm install && pnpm build,保证 dist/ 存在后再在消费方 pnpm install。

当前为便于 file: 引用,仓库内可保留已构建的 dist/;发到私有 registry 后由 CI build 产出即可。

发布

公开包:publishConfig.access = public(任何人可安装,无需私有 registry)。协议变更请 bump 版本,消费方同步升级。
