terminal after trying to run server server

const express = require('express')

const colors = require('colors')

const dotenv = require('dotenv').config()


const {errorHandler} = require('./middleware/errorMiddleware')


const connectDB = require('./config/db')

const port =  process.env.PORT || 5000


connectDB()

const app = express()

app.use(express.json())
app.use(express.urlencoded({extended: false}))


app.use('/api/goals', require('./routes/goalRoutes') )


app.use(errorHandler)


app.listen(port, () => console.log(`Server started on port ${port} `) )

CodePudding user response：

There is already an application listening on port 5000, like the error message suggests. Close any other command prompt/bash that may be running an instance of the application and try again.

CodePudding user response：

Port 5000 is already in use by another application. Either close this port or choose an unused port by:

Changing: const port = process.env.PORT || 5000 to const port = process.env.PORT || <otherport>

or by providing an unused port as an environmental variable.
