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 🙏

plover-benchmark

NPM version build status Test coverage

提供性能监控工具方法,记录模块渲染时间

接入

在应用中引入此插件

npm install --save plover-benchmark

1. 默认情况下不会记录性能日志,可以通过以下配置开启

{
  benchmark: {
    enable: true
  }
}

2. 启动时添加环境变量 DEBUG_BENCHMARK=true 也可以记录日志

$ DEBUG_BENCHMARK=true npm run start

使用

可以调用benchmark service提供的方法来记录调用时间

in middleware

module.exports = function() {
  return function* () {
    ...
    const done = this.benchmark.mark('request-some-data');   // mark start
    yield requestSomeData();
    done();   // mark end
  };
}

开启benchmark后在控制台会得到类似以下输出:

                      plover-benchmark
