You can initialize a class like this
ServerMainFile

const { Server }= require('socket.io')

class socketioserver{
   constructor(){
       this.io=new Server(3000,{cors: {"Access-Control-Allow-Origin": "*",methods: ["GET", "POST", "OPTIONS"]},});
       this.io.on('connection',socket=>{
           console.log(socket.id)
       })
   }
   emit(eventName,data,id){
       if(id) return this.io.to(id).emit(eventName,data)
       this.io.emit(eventName,data)
   }
   on(eventName){
       return new Promise((resolve,reject)=>{
           this.io.on('connection',(socket)=>{
               socket.on(eventName,(data)=>{
                   resolve(data)
               })
           })
       })
   }
   io
}

const ioServer=new socketioserver()
ioServer.emit('apple','
