and its my server.js

const express = require('express');
const bodyParser = require('body-parser');  //서버모듈을위한 
const app = express();
const port = process.env.PORT || 5000;  
 
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended:true})); 

app.get('/api/hello',(req,res) =>{  
    res.send({message : 'hello express!'});  
});
app.listen(port,()=>console.log(`listening on port ${port}`))
