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 🙏

Install

$ npm i egg-longpolling --save

Usage

// {app_root}/config/plugin.js
exports.longpolling = {
  enable: true,
  package: 'egg-longpolling',
};

Configuration

// {app_root}/config/config.default.js
exports.longpolling = {
  // 可订阅的事件名称,需要在业务中调用 publish 触发此事件,支持两种格式定义:
  // 1. 简单的字符串,可直接使用 publish(eventName) 触发
  // 2. 包含资源 id 区分关心的资源,触发时需要附加参数: publish(eventName, resourceId)
  subjects: [ 'event1',  ['event2', { resourceId: ({ category }) => category }]],
  // 订阅相关的请求,如 /longpolling/1/test
  basePath: '/longpolling/',
  // 订阅连接超时时间,单位为秒
  timeout: 30,
};

see config/config.default.js for more detail.

Example

backend:

app.polling.publish('test'); // 单个事件
app.polling.publish([ 'test1', 'test2' ]); // 批量事件,只支持简单格式
app.polling.publish('complex', 'book'); // 通知只关心 book 类的资源

frontend:

async run() {
  const {id} = await fetch('/longpolling/subscription') // response: { id: 1}
  // start to listen
  const result = await fetch('/longpolling/1/test')

  // or fetch with complex type
  // const result = await fetch('/longpolling/2/complex?category=book)

  // after event emit or timeout, will get response
  console.log(result) // { name: 'test', update: 1 } or { name: 'test', timeout: 1 }
  // TODO: start next listen ...
}
