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 🙏

moduleHunter

这是一个模块依赖分析小工具,自带 CLI 工具,可以分析本地的某个目录或线上的某个包的依赖关系

CLI 安装方案

npm install -g moduleHunter

CLI 使用方法

mh -d ./    //可以查看本地工程目录的依赖情况
mh -m chalk //可以查看线上某个模块的依赖情况

会出现如下输出

✔ ──chalk ^2.4.1-->2.4.1
  ├──ansi-styles ^3.2.1
  ├──escape-string-regexp ^1.0.5
  ├──supports-color ^5.3.0

✔ ──ansi-styles ^3.2.1-->3.2.1
  ├──color-convert ^1.9.0

⠴ 正在寻找依赖:color-convert ^1.9.0^C

最后会生成完成的依赖关系:

──chalk 2.4.1
  ├──ansi-styles 3.2.1
  │    ├──color-convert 1.9.3
  │    │    ├──color-name 1.1.3

工程版

安装方法

npm install modulehunter

使用方法

const ModuleHunter = require("modulehunter");
const { getPack, getAllDep, outputPack } = new ModuleHunter();
const { log } = console;
/**
 * Promise Then调用方式
 */

// 不加版本参数,默认是latest
getPack("koa").then(pack => log(pack));

// 不加版本参数,默认是latest
getPack("koa", "1.0.0").then(pack => log(pack));

// getAllDep会返回一个包的信息,其中dependencies信息会被换成嵌套的依赖信息
getAllDep("file", "./").then(pack => outputPack(pack));
getAllDep("mod", "koa").then(pack => outputPack(pack));

// 最后一个参数是扁平化输出,如果设置为true,会把依赖关系扁平化
getAllDep("mod", "koa", true).then(pack => log(pack));

/**
 * Async await 调用方式
 */
(async () => {
  log(await getPack("koa"));
  outputPack(getAllDep("file", "./"));
})();

API

getPack( packName, version = 'latest', returnVal )

获取某个版本的 NPM 包信息,默认返回以下字段:

  • "name"
  • "version"
  • "keywords"
  • "repository"
  • "description"
  • "homepage"
  • "dependencies"

可以通过设置 returnVal 选择需要的字段

getPack("modulehunter", 'latest', ['name', 'version']).then(val => log(val));

getAllDep(type, data, plain = false)

获取一个包的所有依赖关系。

  • type : 'dir' / 'mod'
  • data : 对应的文件夹名或线上包名
  • plain: 是否扁平化

生成的包的dependencies 会被替换成如下形式:

{
	……
      "chalk2.4.1":{
        "version": "2.4.1",
        "inVersion": "^2.4.1",
        "dependencies": {
          "ansi-styles": {
            "version": "3.2.1",
            "inVersion": "^3.2.1",
            "dependencies": {
              "color-convert": {
                "version": "1.9.3",
                "inVersion": "^1.9.0",
                "dependencies": {
                  "color-name": {
                    "version": "1.1.3",
                    "inVersion": "1.1.3",
                    "dependencies": {}
                  }
                }
              }
            }
          },
      ……

扁平化后输出:

"dependencies": {
    "chalk": { "version": "2.4.1", "path": ["chalk 2.4.1"] },
    "ansi-styles": {
      "version": "3.2.1",
      "path": ["chalk 2.4.1", "ansi-styles 3.2.1"]
    },
    "color-convert": {
      "version": "1.9.3",
      "path": ["chalk 2.4.1", "ansi-styles 3.2.1", "color-convert 1.9.3"]
    },
    "color-name": {
      "version": "1.1.3",
      "path": [
        "chalk 2.4.1",
        "ansi-styles 3.2.1",
        "color-convert 1.9.3",
        "color-name 1.1.3"
      ]
    },
    "escape-string-regexp": {
      "version": "1.0.5",
      "path": ["chalk 2.4.1", "escape-string-regexp 1.0.5"]
    },
    "supports-color": {
      "version": "5.5.0",
      "path": ["chalk 2.4.1", "supports-color 5.5.0"]
    },
    ……

outputPack(pack)

与 getAllDep 配合使用

以格式化的形式输出未扁平化模块的依赖关系,如:

版本信息

1.1.1:

  • getAllDep 增加了扁平化plain选项。

1.1.0:

  • 增加了缓存,考虑部分模块循环依赖,还有大量公用模块的隐私,引入缓存能极大的提升查询效率。(缓存借鉴了zensh)
  • 修改了显示文字,更加凸显最终结果

1.0.1:

  • 修改了目录结构

1.0.0:

  • 利用 npm 的接口,递归获取所有的依赖数据
  • 提供了 CLI 工具,方便查看目录和 NPM 线上模块
