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

pro-promise

ProPromise 是一个 JavaScript/TypeScript 库,它通过添加超时功能并提供将回调风格的函数转换为 Promise 的实用程序,扩展了原生 Promise 的功能。

NPM version NPM downloads

安装

你可以通过 npm 安装 ProPromise:

npm install pro-promise

使用

超时功能

ProPromise 允许你为 Promise 设置超时,确保它不会无限期等待。你可以像这样使用它:

import Promise from 'pro-promise';

const myPromise = new Promise((resolve, reject) => {
  // 模拟异步操作
  setTimeout(() => {
    resolve('Promise 成功解决');
  }, 2000);
});

// 设置 1500 毫秒的超时
myPromise.timeout(1500)
  .then((result) => {
    console.log(result);
  })
  .catch((error) => {
    console.error(error);
  });

将回调风格函数转换为 Promise

ProPromise 提供了一个静态方法 promisify,用于将回调风格的函数转换为 Promise。以下是一个示例:

import Promise from 'pro-promise';

function exampleCallbackFunction(callback) {
  setTimeout(() => {
    callback(null, '回调返回的数据');
  }, 1000);
}

const promisifiedFunction = Promise.promisify(exampleCallbackFunction);

promisifiedFunction()
  .then((result) => {
    console.log(result);
  })
  .catch((error) => {
    console.error(error);
  });

API

ProPromise

ProPromise 类扩展了原生的 Promise 类。它接受一个执行函数并提供了额外的方法:

  • timeout(ms: number): ProPromise<T>:为 Promise 添加超时。如果 Promise 在指定时间内不解决或拒绝,它将使用超时错误拒绝。

  • static promisify<T>(fn: (...args: any[]) => void): (...args: any[]) => ProPromise<T>:用于将回调风格函数转换为 Promise 的静态方法。
