ソースコード

const express = require('express')
const app = express()
const port = 3000

var count = 0;

app.use(function(req,res,next){
    count++;    
    console.log(count);
    next();
})

app.use(function(req,res,next){
    count++;    
    console.log(count);
    next();
})

app.use(function(req,res,next){
    count++;    
    console.log(count);
    next();
})

app.get('/', (req, res) => {
  res.send(`Hello World! ${count}`)
})

app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`)
})

結果
