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 🙏

一个方法只处理一件事情, 最终组合起来.

function checkData(args) {
  // 检查数据正确与否;
  // 正确, 继续执行下个方法, 如有需要, 可以把结果return出去;
  // 报错或者return false 则结束; 如需继续, 捕获错误处理不返回false即可
}

function dealData(args2) {
  // 处理数据
  // 完成, 继续执行下个方法, 如有需要, 可以把结果return出去;
  // 报错或者return false 则结束; 如需继续, 捕获错误处理不返回false即可;
}

/** 
 * args 初始参数, 给checkData方法使用, 可以省略;
 * 执行checkData, 失败, 需return false. 之后的方法不在执行;
 *                成功, 可以返回下个方法需要的数据,不需要则不传参;
 * 执行dealData,  如上步骤;
 */
hlcompose(checkData, dealData)(args);

Example

function aa(num) {
  console.log(num); // 1
  return ++num;
}
function bb(num) {
  console.log(num); // 2
  // return false; // 结束
} 
function cc() {
  console.log(3);
  // throw "33333333"; // 抛错也结束
} 
async function dd() {
  try {
    await console.log(4);
    throw "Error";
  } catch (error) {
    // 抛错处理, 不返回false, 所以继续
  }
}
function ee() {
  try {
    console.log(5);
    throw "Error";
  } catch (error) {
    return false; // 结束
  }
}

hlcompose(aa, bb, cc, dd, ee)(1)
