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 🙏

脚手架用途

脚手架也常被称为CLI,全称command-line interface,翻译为命令行界面。前端脚手架CLI,也就是一个命令行工具,如vue-clicreate-react-app

  • 创建项目 + 通用代码:规范项目目录结构、埋点、http 请求、工具方法、组件库

  • git 操作:创建仓库、代码冲突、远程代码同步、创建版本、发布打 tag

  • 构建 + 发布上线:依赖安装和构建、资源上传 cdn、域名绑定、测试/正式服务器

脚手架开发内容

分包、命令注册、参数解析、帮助文档、命令行交互、日志打印、命令行文字变色、网络通信、文件处理

需求分析

  • 命令列表
    • vue create [options] <app-name>一样提供一个初始化项目的命令
    • vue add [options] <plugin> [pluginOptions]提供一个添加插件一样的操作命令
    • vue --version查看版本
    • vue --help提供命令列表
  • 区分生产环境与本地环境

依赖简介

| 包名 | 用途 | | --------- | ------------------------------------------------------------ | | commander | 读取命令行命令,知道用户想要做什么 | | inquirer | 给用户提供一个提问流方式 | | chalk | 颜色插件,用来修改命令行输出样式,通过颜色区分info、error日志,清晰直观 | | ora | 用于显示加载中的效果,类似于前端页面的loading效果 |

实现过程

技术栈:JavaScript + Node

  1. 创建脚手架执行文件:可以在任意目录下执行脚本文件

  2. 解析命令行指令参数(commander.js):创建类似 vue create 的命令

  3. 设计命令行交互(inquirer.js):提供模板选择

  4. 创建工程化模板:利用现有的脚手架模板,如vue-cli,创建一个自己用得惯的,推送到远程仓库

  5. 下载模板(download-git-repo.js)

  6. 美化命令行(ora.js和chalk.js):ora.js添加loading效果;chalk改变命令行颜色

  7. 发布到npm

功能扩展

  • 快速搭建项目目录结构
  • koa2搭建node本地服务模板,用于在日常开发中快速创建模拟后端的接口(用处不大,接口太多了,没法定制)
