NodeJS SDK $project syntax? (mongo query projections)

Goals

(copied from SO post https://stackoverflow.com/questions/63942993/mongodb-realm-nodejs-sdk-project-syntax)

I’m trying to do a simple query where some collection data is returned. I want to filter out the _id field in the results.

From my understanding (based on the documentation) the syntax to do so should look like this:

myCollection.findOne(
        { name: hostName },
        { $project: { _id: 0 } }
)

However when I do this the filter has not been applied, e.g.:

{
  _id: XXXXXXXXXXXXXXXXXXXX,
  name: 'the name',
  ...
}

Can anybody point me in the right direction?

Expected Results

Receiving a filtered query result

Actual Results

The entire query was returned.

Steps to Reproduce

Use the sample code above in your own database. Try to use a projection to filter a query.

@johnsaigle If you go to https://docs.mongodb.com/realm/node/mongodb/, you can leave a comment by clicking “No” to “Was this page useful?”. The docs team will then be notified.

Hello @johnsaigle, I completely understand your confusion - it seems the docs & SDK are not currently aligned. I believe it’s projection instead of $project, as:

myCollection.findOne(
  { name: 'find me' },
  { projection: { _id: 0 } }
)
