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 🙏

npmcli

npm command useage npm 可执行文件的使用 目的: 可以用来做脚手架工具、测试工具、对项目中的内容做批量检查等等

比如我们常见的功能:vue-cli `` $ npm install -g vue-cli $ vue-cli init proj-name

这种命令是如何实现的? vue-cli 实际上是个脚本文件,通过全局安装,能够在命令中直接使用 vue-cli -x, 如果不是全局安装的,还有两种方式:

  1. 使用 npx 直接使用,npx 先在本地查找“vue-cli”脚本,如果没有直接到 npm 包库查找,然后下载下来使用完毕后,立即删除此包,好处是不回操作维护负担,即用即丢。 `` $ npx vue-cli init proj-name

  2. 局部安装 使用 npm run: `` $ npm install vue-cli $ npm run vue-cli init proj-name

或者使用 npx: `` $ npm install vue-cli $ npx vue-cli init proj-name
