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 🙏

简单的天气查询 CLI

TypeScript 学习入门项目之一,可交互的、可以不断响应用户查询的cli工具.

使用

请确保您的机器上安装了 node、ts-node

安装本 cli :npm i -g my-ts-weather

之后执行 my-ts-weather,输入您要查询的城市即可

支持功能

  1. 可以使用 my-ts-weather shell 命令开启查询,而不是用 yarn start。这里在bin/index.ts 中使用了#!/usr/bin/env node,需要 tsc 编译 ts 文件为 js,package.json 中 bin 应该执行的是编译后的 js 文件,而不是 ts 文件,否则 ts 文件的模块引入语法将在 cli 宿主机上运行的时候报错

  2. 启动后可以一直响应用户输入查询下去。这里使用了连续传递回调函数和递归。

开发

编写 index.ts,之后执行 npm run ts-compile,将 index.ts 编译为 index.js

git push 之后再 npm publish

使用了一下几个技术:
  1. inquirer.js 实现可交互命令行
  2. husky 钩子,在项目提交或者推到远程仓库之前运行一些代码检查、测试之类的操作
  3. cli-table3 一款可以在命令行中绘制表格的工具
  4. colors 在 node.js 控制台打印时加上色彩
