It is a mistake the correct method is to show server running message on terminal only when db is connected. like this
mongoose.connect(process.env.URI,{
useNewUrlParser:true,
useUnifiedTopology:true,
useCreateIndex:true,
useFindAndModify:false})
.then(()=>{
app.listen(port,host,()=>{
console.log(http://${host}:${port});
})
console.log("Connected")
})
.catch((err)=>console.log(err))

Because we need to be connected to our DB in order to serve the data to the client when they send a http request
