Help am stuck in the Mongo DB Challenge Install and Set Up Mongoose

JavaScript
1

Tell us what’s happening:
I am having difficulties when running tests on the Mongo DB setup Challenge. I have counter checked my code several time and even tried variations suggested here in the forums and even several versions of mongoose but still I get the prompt that “Mongoose should be connected to a database”
Any assistance will be much appreciated.

Below is my code:

Your code so far
myApp.js

const mongoose = require('mongoose');
var Schema = mongoose.Schema;

mongoose.connect(process.env.MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true });

.env file(not my real password or username)

MONGO_URI='mongodb+srv://username:password123@cluster0-2ewwt.mongodb.net/test?retryWrites=true&w=majority'

Hi,

You can try to log some more information about the connection, like this:

const mongoose = require('mongoose')
mongoose.connect(process.env.MONGO_URI, {
  useNewUrlParser: true,
  useUnifiedTopology: true
})
const db = mongoose.connection;
db.on("error", console.error.bind(console,'connection error:'));
db.once('open', console.log('Connected to MongoDB'));

Hey mate,

I think you need to check a couple of things like:

  • You would need the dotenv dependency imported so javascript can ready the process.env.MONGO_URI reference.

  • Double check MongoDB credentials. If it’s possible, use MongoDB compass or MongoDB shell to test the connection.

  • After setting up mongoose.connect(...), store in a variable and open the connection to see if it gonna open or will throw a error.

var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function() {
  // we're connected!
});

Thank you fshiper I have monitored the log and it outputs Connected the DB plus some errors. However I realized that I did not include the dotenv dependency. Once I added it, I was able to submit and proceed to the next challenge. I appreciate a lot.

Thanks man. After I added the dotenv dependency, all the errors disappeared and I was able to submit my work and proceed to the next challenge. I appreciate your efforts.
