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 version

仿 Koa 中间件控制的 WebSocket 服务,食用简单,上手容易, 支持 GZIP 解压缩和 ProtoBuffer 解压缩配置,觉得小弟写的还行的话,就给个Star⭐️吧~

使用说明

点击安装客户端程序

运行方式

脚本示例

mkdir socket_test
cd socket_test
npm init --yes
npm i -s ssocket 
vim app.js
# 输入此内容
// TS 引入方式 import Ssocket from "ssocket"
const Ssocket = require("ssocket").default;
const server = new Ssocket({ 
    port: 8080
});
server.on("start-up", function(){
    console.log("启动成功")
})

# 然后执行
# Node 安装自动百度
node app.js
// 控制台打印 启动成功

其他配置

const http = require("http")
const Ssocket = require("ssocket").default;
const httpServer = http.createServer()
const server = new Ssocket({
    server: httpServer,
    verifyClient: ({ origin, secure, req }, callback) => {
        callback(true/**返回 false 的话,连接就会中断并给前端返回 403 的HTTP错误码 */)
    }, // 非必传
    perMessageDeflate: true, // 非必传
    maxPayload: 1024 * 1024 * 10, // 最大传输单位 10M // 非必传
    adapter:{// 非必传, 用于服务集群做消息同步
        // MQ 交换机名称前缀
        key:"SocketTipKey",
        redis:{ 
            prefix: 'im',
            host: '127.0.0.1',
            port: '6379',
            expire: 60,
        },
        mqurl:"amqp://username:password@IP"
    }
})

httpServer.listen(8080, function(){
    console.log("启动成功")
})

ProtoBuffer 解压缩配置

const server = new Ssocket({
    /**protos 开启压缩并配置:注 当数据量大于 128 字节的时候自动开启 GZIP 压缩  */
    protos:{ // 非必传
        // 配置请求编码
        request:{
            "test":{
                /**
                 * [required单字段|repeated重复字段|message自定义结构] [string|uint[8|16|32]|float|double] fieldname: 序号同级唯一
                 */
                "required string username": 0,
            }
        },
        // 配置响应编码
        response:{
            "test":{
                /**
                 * [required单字段|repeated重复字段|message自定义结构] [string|uint[8|16|32]|float|double] fieldname: 序号同级唯一
                 */
                "required string username": 0,
                "required uint8 age": 1,
                "required uint32 amount": 2,
                "required string avatar": 3,
                "required Data test": 4,
                "message Data": {
                    "required string usernmae": 0,
                    "repeated List list": 1,
                    "message List": {
                        "required uint32 id": 0,
                    },
                },
            }
        }
    }
})

server.router.ONPath("test", function(ctx, next){
    console.log(ctx.data)// {
    //     username:"测试账号",
    // }
    return {
        username: `登录成功,欢迎${ctx.data.usernmae}`
    }
})

// 前端
client.request("test", {
    username:"测试账号",
}, function(ctx){
    console.log("返回状态", ctx.status)// 200
    console.log("返回说明", ctx.msg)// ok
    console.log("返回数据", ctx.data) // { username:"登录成功,欢迎测试账号" }
})

服务端对象事件控制

server.on("connection", function(client/**SWebSocket */, request/**IncomingMessage */){
    console.lof("接收到一个客户端连接", client.getid())  
})
server.on("reconnection", function(client/**SWebSocket */, id/**client_id*/){
    console.lof("一个客户端重连成功", client.getid())  
})
server.on("route-error", function(ctx, err){ 
    console.log("路由报错", ctx, err) 
})
server.on("close", function(client_id, code, reason){ 
    console.log("连接关闭", client_id, code, reason) 
})

路由事件控制

const Ssocket = require("ssocket").default;
const { Router, Code, CODE } = require("ssocket");
const server = new Ssocket({ port:8080 })

// 扩展错误码
Code.expandStatusCode(201, "没有提交【username】字段")
// 创建路由对象
const main = new Router();
const user = new Router();
const login = new Router();
// 事件中间件拦截校验请求参数
login.USEMiddleware(function(ctx, next){
    // 校验失败返回错误码
    if(!ctx.data.username) return CODE[201];
    // 校验成功,注:所有的中间件必须拥有返回值,没有返回值就返回 next()
    return next();
})
// 在 /login 路径下注册一个请求处理方法
login.ONPath("/login", function(ctx, next){
    return {
        username: `登录成功,欢迎${ctx.data.usernmae}`
    }
})
// 将登陆路由注册到 /user 路由下
user.USEPathMiddleware("/user", login.routes)
main.USEPathMiddleware("user", user.routes);

// 将 main 路由对象注册到 Socket 服务中
server.router.USEMiddleware(main.routes);

// 前端
client.request("user/user/login"/*由上面路由对象会组成这个路由路径*/, { username:"小明" }, function(ctx){
    console.log("返回状态", ctx.status)// 200/201
    console.log("返回说明", ctx.msg)// ok/没有提交【username】字段
    console.log("返回数据", ctx.data) // { username:"登录成功,欢迎小明" }
})

消息控制

login.ONPath("/login", async function(ctx, next){

    ctx.socket // 在上下文中会注入 SWebSocket 对象
    ctx.app // 在上下文中会注入 Application 对象,这个对象等于上面的 Ssocket
    // 加入房间
    ctx.app.join(ctx.socket_id, "roomid_123")
    //离开房间
    ctx.app.leave(ctx.socket_id, "roomid_123")

    // 获取所有的房间ID
    let rooms = await ctx.app.getRoomall()
    // 根据 客户端ID 获取所在的所有房间ID
    let rooms = await ctx.app.getRoomidByid(ctx.socket_id)
    // 根据房间号获取所有的客户端ID
    let clientids = await ctx.app.getClientidByroom("roomid_123")
    // 获取所有的房间总数
    let room_count = await ctx.app.getAllRoomcount()
    // 获取房间内人员数量
    let client_count = await ctx.app.getRoomsize("roomid_123")
    // 判断客户端是否存在啊某个房间
    let flog = await ctx.app.hasRoom(ctx.socket_id, "roomid_123")

    // 单独向某条连接发送消息
    ctx.app.sendSocketMessage(ctx.socket_id, "user.user.login", { username:`登录成功,欢迎${ctx.data.usernmae}` })
    // 单独向某个房间发送消息
    ctx.app.sendRoomMessage("roomid_123", "user.user.login", { username:`登录成功,欢迎${ctx.data.usernmae}` })
    // 向所有连接发送广播消息
    ctx.app.sendBroadcast("user.user.login", { username:`登录成功,欢迎${ctx.data.usernmae}` })

    return {
        username: `登录成功,欢迎${ctx.data.usernmae}`
    }
})


// 前端
client.on("user.user.login", function(ctx){
    console.log("返回状态", ctx.status)// 200
    console.log("返回说明", ctx.msg)// ok
    console.log("返回数据", ctx.data) // { username:"登录成功,欢迎小明" }
})

客户端对象事件控制

server.on("connection", function(client/**SWebSocket */, request/**IncomingMessage */){
    console.log("接收到一个客户端连接", client.getid())

    client.on("close", function(id, code, reason){
        console.log("连接断开, 客户端ID", id)
        console.log("断开代码", code)
        console.log("断开原因", reason)
    })
    client.on("shakehands", function(status){
        console.log("握手状态", status)// 2握手成功|3握手完毕
    })
    client.on("connection", function(id){
        console.log("握手完毕,连接成功, 客户端ID", id)
    })
    client.on("reconnection", function(id){
        console.log("重新连接成功, 客户端ID", id)
    })
    client.on("ping", function(client_now_time){
        console.log("收到客户端一个心跳事件, 此时该客户端当前时间是", client_now_time)
    })
    client.on("pong", function(){
        console.log("服务器回复一个心跳响应事件")
    })

})
