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 🙏

nodejs-coverage-lib

本项目是针对nodejs后台项目,实时生成覆盖率报告使用

安装

npm i nodejs-coverage-lib --save

使用

  1. 在项目的入口文件中添加
require('nodejs-coverage-lib')

上述require的引用确保是在其他文件引用的后面,保证该库是最后引用的,这样子coverage的reset才能够有效

  1. 添加新的依赖项
npm i nyc --save

这个是为了能够通过nyc来启动node的入口文件

  1. 在package.json启动脚本中增加nyc的启动方式
"scripts": {
    "start": "node index.js",
    "cov": "nyc node index.js"
},

如上述,原先的启动命令是 node index.js, 新的则为 nyc node index.js

  1. 在项目的package.json中添加如下的内容
"nyc": {
    "parser-plugins": [
      "typescript",
      "jsx",
      "asyncGenerators",
      "bigInt",
      "classProperties",
      "classPrivateProperties",
      "dynamicImport",
      "importMeta",
      "objectRestSpread",
      "optionalCatchBinding",
      "decorators-legacy"
    ],
    "all": true,
    "compact": false,
    "reporter": [
      "html"
    ]
}

注意

该覆盖率工具会额外监听8787的端口,若想要与自定义端口可直接在启动服务的命令后面添加 --port xxx进行修改

完成测试以后,即可通过访问xx.xx.xx.xx:8787/download 进行下载覆盖率文件
