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 🙏

dsh-guard

v1.0.0

Published

DSH 运行期守护:启动成功后自动存档;插件加载失败时自动回退到上次良好快照并重启。

Readme

dsh-guard

DSH 开发配套守护插件:滚动快照 + 失败自动回退 + 本机管理面板。

能力

  • 滚动快照:每次存档保留最近 N 份(默认 5,带时间戳+原因),同时镜像 last-good 供外部启动器/bat 互操作
  • 自动存档:启动成功且度过宽限期后自动存档(reason=auto)
  • 自动回退:监听到插件运行失败,三道护栏内自动回退 last-good(每启动一次、宽限期内、快照早于本次启动)
  • 管理面板(仅本机):http://127.0.0.1:<端口>/dsh-guard —— 状态 / 快照列表 / 一键存档 / 回退 / 恢复备份 / 事件日志
  • 管理 API(仅本机):/api/dsh-guard/{status,snapshots,backups,log,save,rollback,restore}
  • 事件日志snapshotRoot/guard.log

配置(profile 补丁层,均可省略)

- id: dsh-guard
  config:
    snapshotRoot: D:\path\to\snapshots
    profileDir: C:\path\to\profiles\web
    sourceDirs: [D:\path\to\plugin-src]
    restartCommand: D:\path\to\restart.bat   # 空 = 只回退不重启
    graceMs: 120000
    autoSaveDelayMs: 150000
    keepSnapshots: 5

安全边界(重要)

  • boot 崩坏插件救不了:进程在启动期崩溃时插件无法运行,boot 救援由外部启动器承担(见 dsh-balance-float 仓库的 windows/launch-dsh.vbs SNAP_TOOL 机制)
  • 管理面板/API 仅限本机回环地址访问
  • 每次启动最多自动回退一次(防死循环)
