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

@hve/channel

A buffered channel library for asynchronous data transmission

비동기 데이터 전송을 위한 버퍼링된 채널 라이브러리

Go 언어의 채널(Channel)에서 영감을 받아 JavaScript/TypeScript에서 구현한 라이브러리입니다.

Installation

npm install @hve/channel

Example

import Channel from '@hve/channel';

async function example() {
  const channel = new Channel<number>();
  
  await channel.produce(1);
  await channel.produce(2);
  await channel.produce(3);
  
  const value1 = await channel.consume(); // 1
  const value2 = await channel.consume(); // 2
  const value3 = await channel.consume(); // 3
  
  console.log(value1, value2, value3); // 1 2 3
}

Usage

Constructor

constructor(bufferSize?: number)

bufferSize는 채널의 버퍼 크기를 설정합니다.

  • undefined : 무제한 버퍼
    • 버퍼 크기에 제한이 없으며, produce시 항상 즉시 반환됩니다.
  • 0 : 동기식 채널
    • produce 시 즉시 블로킹되며, consume 전까지 대기합니다.
  • > 0 : 유한 버퍼
    • 버퍼가 가득 차기 전까지 produce 시 즉시 반환됩니다.
    • 버퍼가 가득 차면 대기합니다.

Methods

async produce(item: T): Promise<void>

채널에 데이터를 전송합니다.

async consume(): Promise<T>

채널에서 데이터를 수신합니다.

버퍼 크기에 관계없이 버퍼에 채널에 데이터가 없다면 대기합니다.
