How can I obtain services to MongoDB Realm App?

Question

Hi there fellow coders,

Maybe one of you could bridge the gap I seem to be having.

I'm new to Mongo and tried to set up a database. Then created a Realm App.

Having done that, the doco seems to indicate I should be able to use the line:

const mongo = app.services.mongodb("");

However, I get an error saying "Cannot read property 'mongodb' of undefined". Obviously, it's because there is no services against app.

I tried looking this up online, but found no answers. Hoping someone experienced could guide me as to what is missing or what I'm clearly not seeing.

TIA!

Are you using MongoDB 4.4?

Are you using MongoDB Atlas? Realm sync does not work for on-premises MongoDB.

If you're using all that, I would go to https://realm.mongodb.com and click "Create a New App" and then the screen that shows up, you pick the cluster to connect with and that's the service. (or choose the 'we'll create one for you' option).

Services and functions are now available on User instance

const mongo = user.mongoClient("");   
const db = mongo.db("");
const collection = db.collection("");'

The default name is mongodb-atlas:

const mongo = app.services.mongodb("mongodb-atlas");
