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 🙏

Socket

若想启用socket服务,需要做以下几步操作:

服务端

配置

    1. 安装依赖
yarn add @yunflyjs/yunfly-plugin-socket
    1. config.plugin.ts 中声明插件
const plugins: { [key: string]: string }[] = [
  {
    name: 'socket',
    package: '@yunflyjs/yunfly-plugin-socket',
    lifeHook: 'afterStart'
  },
];
export default plugins;

使用

  • 根目录src下新增socket文件夹

  • socket 文件夹下可新建 controllermiddleware 两个文件夹

  • middleware 可建多个,执行时没有固定的先后顺序,代码案例如下:

export default function socketMiddleware (socket: any) {
  return socket.use((socket: any, next: (err?: any) => Promise<any>) => {

    // middleware. do something

    return next();
  });
}
  • controller 文件夹下固定 MainController.ts 为socket接收入口, MainController 中代码固定如下:
export default function main (socket: any) {
  // 向客户端发送数据案例
  socket.emit('hello', (data: any) => {
    console.log(data); 
  });
  // 服务端就收数据案例
  socket.on('message', (...args: any[]) => {
    console.log(args)
  });
}

客户端

由于服务端 socket.io 为2.x版本, 客户端也相应的需要使用 2.x 版本

安装依赖

yarn add socket.io-client@2

基础使用

import io from 'socket.io-client';

const socket = io('http://127.0.0.1:3000/', {
  path: '/socket.io', // 此处需要跟服务端path保持一致
  transports: ['websocket'],
})

// 接受数据案例
socket.on('hello', (...args: any[]) => {
  console.log(args)
});

// 定时发送数据案例
setInterval(() => {
  socket.emit('message', 'hello world!')
}, 2000)
