How to access collection elements in meteor.js?

Question

JavaScript

I apologize for such a simple question, but the meteor.js documentation is very brief, many points are described rather vaguely. In general, how should the elements of collections be accessed in meteor ? Let's say we have a built-in User collection that stores user data. The user ID can be obtained using the following code on the client side:
return Meteor.userId()
However, if you need to display other data (login, mail), then there is already a problem. After something like this code, the inscription [object Object] is displayed :

return Meteor.users.find({emails:"[email protected]"})

What is the correct syntax for displaying collection items and what am I missing?

Answer 1

The problem is not in the meteor documentation, you need to know js before you start working on fancy meteors :)
Everything works correctly, you get back an object containing information about the user.
If in short:

Meteor.users.find({emails:"[email protected]"})._id // Если я не ошибаюсь хранится ID тут
Meteor.users.find({emails:"[email protected]"}).email
Meteor.users.find({emails:"[email protected]"}).login
Meteor.users.find({emails:"[email protected]"}).blah-blah

Answer 2

Not quite right
The find method returns the cursor, not the document itself from the database
To return the document itself - use .findOne or find(query,options).fetch() - which will return an array of documents
