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 🙏

fetchpackage

在函数调用中下载 NPM 包

简介

某些特殊的情况下,无法预先下载安装 NPM 包,需要在代码运行时动态下载安装 NPM 包。使用 fetchpackage 可以直接在代码执行时动态下载安装指定的 NPM 包

安装

npm i fetchpackage

使用

const fetchpackage = require('fetchpackage')

fetchpackage({
	path: './',    // 指定下载目录
	name: 'package_name',    // 指定下载的 NPM 包名
	registry: 'taobao',    // 指定下载源
	global: false,    // 指定是否全局安装
})

参数

| 属性名 | 类型 | 示例 | 是否必填 | 含义 | | :------: | :-----: | :------: | :------: | :----------------------------------------------------------: | | path | string | '/data' | 否 | 下载路径,默认为当前目录(可使用别名参数 cwd) | | name | string | 'axios' | 是 | 要下载的 NPM 包的包名 | | registry | string | 'taobao' | 否 | 下载源,默认官方源。official 或 npm 表示使用官方源,taobao 或 cnpm 表示使用淘宝源。其他源请直接填入源地址。 | | global | boolean | false | 否 | 是否全局安装,默认为否 |

返回

函数将返回一个 Promise —— 下载成功将返回对应 NPM 包的包名+版本号,例如 '[email protected]' ,即包目录下的 package.json 文件的 _id 字段值。下载失败将返回错误原因。
