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 🙏

Readme

scanDirEach(path, [worker = () => true, raw = false])

并行扫描文件夹,可在扫描的同时更新或过滤数据,一定程度复用遍历。

使用

  • path 待扫描的路径,必需提供,{String}
  • worker 处理器,如果扫描的同时需要更新、过滤操作可提供,一定程度复用穷举,可选,{ Function }
    • 返回 { Object | Boolean | Promise }
      • false 过滤掉当前扫描结果
      • true 保留当前扫描结果
      • 对象字面量,保留 / 更新当前扫描结果
      • 如果需要在处理器中需要安放些异步操作,如远程数据请求,可在处理器中返回一个 Promise,该 Promise 可返回,
        • false 过滤掉当前扫描结果
        • true 保留当前扫描结果
        • 对象字面量,保留 / 更新当前扫描结果
        • 其它类型则默认为没有任何处理
      • 其它类型则默认为没有任何处理
  • raw 是否专门返回未加工的扫描结果,使用 worker 后才会生效,默认 false可选,{ Boolean }
  • 返回,扫描结果 { Array }
    • 如果设置了 rawtrue,则返回 二维数组,第一项为加工后的扫描结果,第二项为未加工的扫描结果
    • 默认返回 一维数组,即:加工后的扫描结果
import { log } from "console";
import scanDirEach from "@iyowei/scan-dir-each";

(async () => {
  const got = await scanDirEach(
    process.cwd(),
    (cur, index) =>
      new Promise((resolve) => {
        // 可以做些异步操作,如远程数据请求
        resolve(index % 2 === 0 ? cur : false);
      }),
    false
  );

  log(got);

  /**
   * [
   *   {
   *     path: '',
   *     dirent: [Dirent]
   *   },
   *   ...
   * ]
   */
})();

  • lsDirSync(),串行扫描文件夹;
  • lsDir(),并行扫描文件夹;
  • scanDirEachSync(),可在扫描的同时更新或过滤数据,串行 实现;
  • scanDirSync()worker 选填,有 worker,行为同 scanDirEachSync() 一致,否则与 lsDirSync() 一致,如果项目中同时使用了 scanDirEachSync()lsDirSync(),则推荐使用 scanDirSync()
  • scanDir()worker 选填,有 worker,行为同 scanDirEach() 一致,否则与 lsDir() 一致,如果项目中同时使用了 scanDirEach()lsDir(),则推荐使用 scanDir()
