a very common error with MongoDB atlas. better still follow this procedure

  1. Install Mongo DB compass

  2. use Default setting

hostname: localhost & port 27017

  1. create a database with the project name and then collection: user
  2. Connect with the code below on entry js. route

mongoose.connect('mongodb://localhost/projectname') .then(() => console.log('mongo db working')) .catch(err => console.log('ERROR is', err))

The issue is with your keys. Try using:

module.exports= {
  mongoURI : "your-uri-string",
  options:{key:value}
}

And use the keys as:

mongoose.connect(db.mongoURI,options);
