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 🙏

npm i @dependahub/event

Example

import {event} from '@dependahub/event';

// イベントの購読 A
const subscriptionA = event.subscribe('eventName', async payload => {
  // 何らかの処理A
});

// イベントの購読 B
const subscriptionB = event.subscribe('eventName', async payload => {
  // 何らかの処理B
});

// イベントの購読解除
subscriptionA.unsubscribe();

// イベントの発火
await event.push('eventName', payload); // subscriptionB のみ発火

// イベントの削除
event.remove('eventName');
await event.push('eventName', payload); // 何も発火しません

Features

イベントの購読

イベント名を指定して購読登録します。イベント発火時には第2引数のコールバック関数が実行されます。

const subscription = event.subscribe('eventName', async payload => {
  // イベント発火時に実行する処理
  console.log('イベントを受信しました:', payload);
});

イベントの購読解除

subscribe()の戻り値から購読を解除できます。

// 購読を解除
subscription.unsubscribe();

イベントの送信

指定したイベント名に対して、データ(payload)を送信します。登録されているすべてのコールバック関数が非同期に実行されます。

// payloadには任意のデータを渡せます
const payload = { message: 'こんにちは', timestamp: Date.now() };
await event.push('eventName', payload);

イベントの削除

指定したイベント名に関連するすべての購読を削除します。

// eventNameに登録されているすべての購読が削除されます
event.remove('eventName');
