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 🙏

多房间聊天室案例

本案例采用socket.io实现多房间多人聊天,主要实现了两个类,一个是用户User,一个是房间Rooms

安装使用

npm install socket.io-rooms --save

demo演示

把项目clone下来后,执行npm start,然后打开example/index.html即可品尝到演示效果

使用方式

服务端

const {User,Rooms}  = require('socket.io-rooms')
const server = require('http').createServer();
const io = require('socket.io')(server);

//大厅
io.on('connection', client => {
    let user = new User();
    client.emit('user',user);
    client.on('join', data => {
        /* 加入某个房间 */
        Rooms.join(data,user,io,client)
    });
    client.on('message',msg=>{
        if(user.roomId){
            // io.to(user.roomId).emit('message',msg)
            if(msg.type == 'update'){
                user.update(msg.body);
            }
            msg.user = user.uid;
            Rooms.send(user.roomId,msg)
        }else{
            io.emit('message',msg)
        }
        console.log(msg)
    })
    client.on('disconnect', () => {
        /* … */
        console.log("连接断开")
        Rooms.leave(user)
    });
});
server.listen(80);

这里传输统一使用JSON格式,消息title也以message为主,这里端口写的80,你可以使用其他端口,如果你是Express,也可以共用80端口。

客户端调用

const socket = io('http://localhost');
log =(...args)=>{
    document.getElementById('log').innerHTML +='<br/>'+args.map(item=>JSON.stringify(item)).join(' ')+'=>'+(+new Date());
} 

log(socket.id)
let user ={},room,client;
socket.on('connect', (c) => {
    log('connect ...', socket.id);
    socket.on('user',u=>{
        user = u;
        log('用户ID',u.uid)
    });
});
socket.on('message',msg=>{
    log('message:',msg)
});
function joinroom(num){
    //加入房间号为1的房间
    socket.emit('join',num);
}
function send(){
    let msg = document.getElementById('msg').value;
    socket.emit('message',{type:'TALK',body:msg})
    // setInterval(function(){
    //     socket.emit('message',{type:'TALK',body:+new Date()})
    // },2000)
}
