View Mongo DB in Mongo compass

Question

I'm new to MongoDB and Node . I have connected to Mongo using below

const mongoose = require("mongoose")
mongoose.connect('mongodb://localhost/testaroo', {
  useNewUrlParser: true
})
mongoose.connection.once('open', function() {
  console.log("Connection has been made ..")
}).on('error', function(error) {
  console.log("Connection error", error)
});

And I created the below model

const mongoose = require('mongoose')
const schema = mongoose.Schema;
const marioCharSchema = new schema({
    name: String, // Optional
    weight: Number // Optional
})
const marioCharModel = mongoose.model('mariochar', marioCharSchema);
module.exports = marioCharModel;

EDIT

Inserting Data

const assert = require('assert');
const mariochar = require('../test/models/mariochar')

// Describe tests
describe('Saving records', function () {

    //Create tests
    it("Saving records to database", function (done) {
        

        const char = new mariochar({
            name = "Test",
            weight: 45
        });

        char.save().then(
            function () {
                assert(char.isNew === false)
                done();
            }
        )
    
    })

})

And I tried to save a new record to this model and I tested it using mocha and it saved successfully. Now I want to view my database and my records using Mongo compass .

I tried to connect to mongodb://localhost/testaroo on port 27017 but I couldn't see my database. So what I'm missing here?

FIXED

For future viewers I fixed it by passing this option useUnifiedTopology : true to the to the MongoClient constructor

mongoose.connect('mongodb://localhost/Mydb', { useNewUrlParser: true, useUnifiedTopology: true })

Answer 1

Use mongo shell to insert and retrieve documents from the database, verify this works.

Use compass to view documents you inserted via the shell, verify this works.

Insert documents in your application and retrieve them via the shell, verify this works.

At this point whatever issue you have between your application and compass should be resolved.
