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

yo-helper

Yeoman generator helper

Install

npm install --save yo-helper

Simplest use

var yeoman = require('yeoman-generator');
var yoHelper = require('yo-helper');

var moduleName;
module.exports = yeoman.generators.Base.extend({
  prompting: {
    welcome: yoHelper.welcome(),

    askForModuleName: yoHelper.askForModuleName(function(data) {
      moduleName = this.moduleName = data.moduleName;
    }),

    askForUserData: yoHelper.askForUserData(moduleName, function(data) {
      this.user = data;
    }),

    askForModuleInfo: function() {
      var done = this.async();

      var prompts = [{
        name: 'description',
        message: 'Description',
        default: 'The best module ever.'
      },{
        name: 'version',
        message: 'Version',
        default: '0.0.0'
      }, {
        name: 'license',
        message: 'License',
        default: 'MIT'
      }, {
        type: 'confirm',
        name: 'skipInstall',
        message: 'Do you need skip npm install?',
        default: false
      }];

      this.prompt(prompts, function(answers) {
        this.props = props;
        done();
      }.bind(this));
    }
  },

  writing: yoHelper.writing(),

  install: function () {
    var skip = this.answers['skipInstall'] || this.options['skip-install'];

    this.installDependencies({
      skipInstall: skip
    });
  }
});

normalize(str, [nameCase])

转换字符串为指定的命名风格,有如下三种:

  • camel:驼峰式,默认的风格,如 nodePlugin, yoHelper
  • kebab:中划线式,如 node-plugin, yo-helper
  • snake:下划线式,如 node_plugin, yo_helper

在使用 yo 的时候,可以带上参数 --name-case=snake 来指定你需要设置的命名风格

welcome(generatorName)

@params generatorName string optional

@return function

输出 yeoman 的人形图片及文案,xxx 名字会自动根据你的参数(如 yo xxx)得到,不过你也可以在函数参数中指定其名称

     _-----_
    |       |    .--------------------------.
    |--(o)--|    |   Welcome to the lovely  |
   `---------´   |   xxx generator!   |
    ( _´U`_ )    '--------------------------'
    /___A___\    
     |  ~  |     
   __'.___.'__   
 ´   `  |° ´ Y ` 

writing(process)

@params process function optional 处理程序

此函数会自动把 template 目录下的所有文件移动到用户当前目录下:

  • 如果文件前缀含有 _,则自动会去掉
  • 如果文件在 srctest 目录中,里面的文件的命名风格会自动转换成 --name-case 指定的风格,或使用默认的 camel 风格
  • 如果文件的后缀名是 ._tpl 的话,则会用 yo 的 template 方法,替换文件中的变量,并在生成新文件的时候去掉 ._tpl 的后缀;
  • 如果文件的后缀名不是 ._tpl 的话,则直接用 yo 的 copy 方法,把文件移动到目标文件夹,不做其它任何处理;
  • 如果参数 process 存在,并且其结果返回 false 的话,则不会进行上面两步的处理,直接退出

askForModuleName(callback)

@params callback function 回调函数,其参数是 { moduleName: [string], pkgName: [string] }

@return function

提示用户输入项目名称,如果名称已经存在,会提醒用户是否输入一个新的 NPM Package Name

askForGithubUser(callback, opts)

@params callback function 回调函数,其参数是 github api 返回

@params opts object optional 参数,目前只支持设置 exitOnEmptyUser,默认为 true,即如果没有找到对应的 github 用户就直接退出

@return function

askForUserData(callback, opts)

依赖于 askForModuleName,也就是说必须要执行函数 askForModuleName

此函数支持没有 github 帐号的用户,让他们输入一些额外的信息,包含了 askForGithubUser 功能,它的 callback 返回的数据格式为:

{
  name: {string},
  email: {string},
  project_url: {string},
  issue_url: {string},
  github: {object}  // all data that askForGithubUser return
}

askForDependencies(dependencies, callback)

@params dependencies array, example:

[
  {
    name: 'lodash',
    description: 'A utility library'
  },
  {
    name: 'q',
    description: 'A library for promises',
    checked: false
  },
  {
    name: 'debug'
  }
]

@params callback function, callback 的参数有两个,一个 {pkgName: pkgVersion, ...}, 第二个是可以直接应用到 package.json 文件中的 dependencies 字符串
