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 🙏

安装

  $ npm install dyi-tool --save-dev

使用

 import {copyFile, copyDir} from 'dyi-tool'

复制文件

/**
 * 复制文件
 * @param path: string  需要复制的文件
 * @param targetPath: string  保存的目标文件
 * @param type?: string 保存文件的类型,m-小文件 l/L-大文件, 默认: m 
 * 
 * 用法: copyFile(path, targetPath, type)
 */

 // 复制小文件
 copyFile('./index.js', './src/index.js')

 // 复制大文件
 copyFile(./index.js', './src/index.js', 'l')

// 目录如下

├─ index.ts 
├─ src
│  ├─ index.ts
│  ....(省略其他的)

复制文件夹

 /**
 * 复制目录
 * @param dir: string  需要复制的目录,为空会抛出异常
 * @param targetDir: string  保存的目标目录,为空会在根目录粘贴该文件,文件名取默认值
 * @param callback?: ({
 *          code: string // 错误码
 *          path: string // 当前异常文件的位置
 *          message: string // 错误信息
 *        }) => void 异常回调,可选
 * 
 * 用法: copyDir(dir, targetDir, callback)
 */

// 复制目录
copyDir('src/utils', 'src/utils2')

目录如下:

├─ src
│  ├─ utils
│  ├─── index.ts
│  ├─ utils2
│  ├─── index.ts
│  ....(省略其他的)

// 复制过程出现异常,该过程是异步的
copyDir('src/utils', 'src/utils2', (error) => {
  console.log('异常回调', error)
})

// 当目标文件夹为空或者不存在时
const res = copyDir('', 'src/utils2')
// res -> false
