I have an array of ids and I want to retrieve all of them at once. Is this possible, can I pass an array of ids somehow and have all of them returned to me? If so, how?

I'm using the node-native driver.

Thanks!

you need to use $in operator, that would give you desired result.

https://docs.mongodb.com/manual/reference/operator/query/in/

Using the $in operator you can do something similar to:

const ids = ["123", "456","789"]
const items = await db
     .collection("items")
     .find({ "_id": { "$in": ids.map(id => new ObjectId(id)) } })
     .toArray()
