These work fine:

myCollection.find();
myCollection.findOne();

This does not:

           myCollection.find().next();
                               ^
TypeError: Object #<Cursor> has no method 'next'

But documentation says:

cursor.next()

Returns: The next document in the cursor returned by the db.collection.find() method.

Any ideas on what I'm doing wrong?

• javascript
• node.js
• mongodb

• 1 What is myCollection (how did you create it)? What mongodb driver do you use? Which version? Could you provide an SSCCE? – Zeta Commented Jul 23, 2013 at 0:19
• There's a nextObject on the cursor in the MongoDB Node.JS driver: mongodb.github.io/node-mongodb-native/api-generated/…, but no next. – WiredPrairie Commented Jul 23, 2013 at 0:32

While related, the JavaScript Methods in MongoDB are not the same as those in the native driver for Node.js.

The former, including cursor.next(), make up MongoDB's own API and are similar to SQL mands in relational databases. Use these when connected through the mongo shell.

The equivalent of cursor.next() within the Node.js driver API is cursor.nextObject().

Just to note that cursor.next() replaces nextObject() in 2.0 and is available.
