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 🙏

Readme

@liuhange/dsh-data-lineage

数据血缘追踪插件:追踪数据从源头到最终产品的流转路径,支持链式追溯和 Mermaid 可视化。

Tool 接口

trace_data_lineage

导出数据血缘追踪报告,支持 JSON/Mermaid/Markdown 三种格式。

  • lineageFilePath (string, 必填): 血缘记录文件路径(lineage.json)

血缘记录

每个步骤记录:步骤名、时间戳、输入文件路径+hash、输出文件路径+hash、变换规则、处理参数。

编排嵌入

通过 LineageHook 在编排流程中自动嵌入血缘记录:

  • recordBefore(): Tool 调用前记录输入文件 hash
  • recordAfter(): Tool 调用后记录输出文件 hash 和变换规则
  • enabled = false 时零开销,不计算 hash,不生成文件

配置节点

business-rules.jsonlineage 节点。缺失时默认禁用(enabled: false),编排行为与 v1.0 完全一致。

v1.0 兼容性

血缘功能默认禁用,不影响 v1.0 编排行为。启用时额外耗时 ≤ 1 秒/Tool调用。
