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 🙏

使用 node 自定义一个 小型脚手架

功能概览

  • 根据项目名创建通用项目结构
  • 当项目名已经存在,则会询问是否将之前的项目进行覆盖

实现步骤

准备工作

初始化我们的脚手架结构

  • node_modules
  • templates // 存放项目模板文件
    • ...模板文件
  • cli.js // cli 入口文件

安装所需的插件

 yarn add inquirer ejs del --dev

插件说明:inquirer 提供用户输入, ejs 用于渲染html模板, del 用于删除文件,当项目已经存在时,可用这个插件删除掉之前的项目文件。

编写cli 入口 cli.js

  1. 首先将#!/usr/bin/env node 加在文件的顶部,作为声明头,指名这个脚本文件的解释程序 用node来运行。
  2. 使用inquirer 构建用户输入提示,让用户输入项目名
  3. 接收用户的信息,判断用户输入的项目名是否已经存在于当前目录当中,如果已存在,则继续提示用户是否进行覆盖,yes/no,回答yes 则会将之前的文件全部清除,no 则会终止程序。
  4. 读取所有的文件路径,并创建上级文件夹
  5. 根据所读取到的路径创建文件,当文件后缀为.html时,使用 ejs 渲染html模板,然后再根据渲染结果创建文件。
