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

@emtpzh/watch-folder

一个简单的文件夹监控工具,当检测到文件夹内容变化时执行指定的命令。基于 inotify-tools 实现。

系统要求

  • Linux/Unix 系统(需要安装 inotify-tools)
  • 安装 inotify-tools:
    # Ubuntu/Debian
    sudo apt-get install inotify-tools
    
    # CentOS/RHEL
    sudo yum install inotify-tools

安装

npm install -g @emtpzh/watch-folder

使用方法

npx @emtpzh/watch-folder <要监控的文件夹> <要执行的命令>

示例

# 监控 src 文件夹,当文件变化时执行 npm run build
npx @emtpzh/watch-folder ./src "npm run build"

# 监控当前目录,当文件变化时执行 echo 命令
npx @emtpzh/watch-folder . "echo 文件发生变更"

特性

  • 支持监控文件夹的创建、修改、删除事件
  • 内置 1 秒防抖,避免频繁执行命令
  • 自动终止正在运行的命令,确保命令按顺序执行
  • 基于 inotify-tools 实现,性能更好

注意事项

  • 命令会在检测到文件变化后延迟 1 秒执行,以避免频繁触发
  • 使用 Ctrl+C 可以安全退出监控
