Unresolved function or method connect() mongoose

Question

I am learning Mongoose from JavaScript Everywhere book, and this is the code I had to write:

const mongoose = require('mongoose');
const mongoose = require('mongoose');
module.exports = {
  connect: DB_HOST => {
    mongoose.connect(DB_HOST);
    mongoose.connection.on('error', err => {
      console.error(err);
      console.log('MongoDB connection error. Please make sure MongoDB is running.');
      process.exit();
    });
  },
  close: () => {
    mongoose.connection.close();
  }
}

when i hover over connect and connection, it shows Unresolved function or method connect() and Unresolved variable connection accordingly. My guess is that the book about an older version of mongoose, and in the newest version it is simply removed. What is the new function and variable for it?

I'm also learning Mongoose and have the same situation as you; here's how I fixed my error – you can use it as a reference to fix your code:

const {connect: connect1} = require('mongoose')

async function connect() {
    try {
        await connect1('DB_HOST')

        console.log('\n Connected successfully')
    } catch (err) {
        console.log('\n Disconnect')

    }
}

module.exports = { connect }
