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 🙏

@ohkit/async

v0.0.5

Published

some async utils

Readme

@ohkit/async

Promise串行管道工具,用于管理异步任务的顺序执行

安装

npm install @ohkit/async

功能特性

  • 管理Promise任务的串行执行
  • 支持任务队列
  • 提供任务执行状态回调
  • 灵活的任务触发控制

基本用法

import { PromisePipe } from '@ohkit/async';

const pipe = new PromisePipe();

// 添加并立即执行任务
pipe.add(async () => {
  await fetch('/api/data1');
});

// 添加延迟执行任务
pipe.add(async () => {
  await fetch('/api/data2');
}, { fireImmediately: false });

// 手动启动执行
pipe.start();

API 说明

PromisePipe 类

方法

| 方法 | 说明 | 参数 | 返回值 | |------|------|------|--------| | add | 添加异步任务 | fun: PromiseTask, opt?: { returnWaitAll?: boolean, fireImmediately?: boolean } | Promise<T> | | start | 开始执行队列中的任务 | - | - |

参数说明

  • PromiseTask: () => Promise<T> | void 异步任务函数
  • returnWaitAll: 是否等待所有任务完成
  • fireImmediately: 是否立即执行任务

高级用法

获取任务执行结果

const result = await pipe.add(async () => {
  return await fetch('/api/data');
}, { returnWaitAll: true });

任务状态回调

pipe.add(async () => {
  // 任务逻辑
}, {
  fireImmediately: false,
  returnWaitAll: true
}).then(res => {
  console.log('任务完成:', res);
});

注意事项

  1. 任务函数需要返回Promise才能保证串行执行
  2. 默认情况下任务会立即执行
  3. 使用returnWaitAll表示需要等待pipe中所有任务完成后才resolve
