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 🙏

在npm install 的时候发生了什么?

  • 首先安装的依赖都会存放在根目录的node_modules,默认采用扁平化的方式安装,并且排序规则.bin第一个然后是@系列,再然后字母排序,并且使用的算法是广度有限遍历,在遍历依赖数的时候npm会首先处理目录下的依赖,然后逐层处理每一个依赖包的依赖,直到所有依赖都被处理完毕 在处理每个依赖是 npm 会检查版本号是否符合依赖树中其他依赖的版本要求,不符合,会尝试安装合适的版本

在 npm run 的时候会发生什么

  • 首先在当前项目先去找有没有node_modules/.bin 没有
  • 去全局找 没有
  • 去环境变量找 没有
  • 报错

npm 的生命周期

  • "predev" 会在常规命令之前调用
  • "postdev" 会在常规命令之后调用
