i got this error in my terminal when i run my index.js file as a 'npx nodemon .\index.js'

this is my 'index.js':

const connectToMongo = require('./database');
connectToMongo();

this is my dabase.js:

const mongoose = require('mongoose')
const mongoURI = 'mongodb://localhost:27017/'

const connectToMongo = ()=>{
    mongoose.connect(mongoURI,()=>{
        console.log('connected to mongo')
    })
}

module.exports = connectToMongo;

this is my terminal error:

  throw new MongooseError('Mongoose.prototype.connect() no longer accepts a callback');
      ^

MongooseError: Mongoose.prototype.connect() no longer accepts a callback at Mongoose.connect (D:\React\inotebook\backend\node_modules\mongoose\lib\index.js:400:11) at connectToMongo (D:\React\inotebook\backend\database.js:5:14) at Object.

const mongoose = require('mongoose');
const mongoURI = "mongodb://localhost:27017"

const connectToMongo = async () => {
try {
    mongoose.set('strictQuery', false)
    mongoose.connect(mongoURI) 
    console.log('Mongo connected')
}
catch(error) {
    console.log(error)
    process.exit()
}
}
module.exports = connectToMongo;

this worked for me

  • You might not need to add the `process.exit()` line there, as that action (i.e. stopping the entire application) might not necessarily be the action a user might want to take should the connection fail. – Deolu A Apr 15 '23 at 20:24
