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 🙏

easy-File-Access-Api

这是一个易用的浏览器文件系统API。

浏览器读取文件是通过 File System Access API 实现的。但是这个API用法不太符合人类直觉。简单的想根据路径读取一个文本文件也要经过获取handle,处理流等等的过程。本项目对原生的File System Access Api进行封装,暴露出一套易用的接口。

里面的每个函数都支持深层次的操作,可以直接write('/a/b/c/d/e/f.txt'),而不论这些目录是否存在(不存在则自动创建)

用法

import EasyFileAccess from 'easy-file-access-api'

var fs: EasyFileAccess

let load_some = async ()=>{
  const handle = await window.showDirectoryPicker()
  fs = new EasyFileAccess(handle)
}

var write_some= async ()=>{  

  console.log(  fs.write('/a/c.txt', 'asdfasdfasdfasdf') )
}

demo

git clone https://github.com/weihongliang233/easy-File-Access-Api.git

cd easy-File-Access-Api
npm install 
npm run watch

打开浏览器,访问http://localhost:8000/

打开F12开发者工具

网页上有两个按钮:Load和test

点击Load弹出文件夹选择窗,选中本项目中的test文件(选其他文件夹不行)

选完后点击test

会自动开始遍历测试用例,控制台输出直至全部成功。

各函数用法请看index.test.ts
