I just installed the latest versions of node.js and MongoDB and a driver for node.js: MongoJS
Now I tried to find out (with good performance due a high load app) if a record exists in the database. I tried this query but all I get is an error:
var query = db.users.find({ nickname: 'test' }).limit(1);
console.log(query.size());
// or also
// console.log(query.length);
// => undefinied
Error:
TypeError: Object [object Object] has no method 'size'
Via console.log(typeof query)
I just get object
.
If I just log query
I get this:
{ _readableState:
{ highWaterMark: 16384,
buffer: [],
length: 0,
pipes: null,
pipesCount: 0,
flowing: false,
ended: false,
endEmitted: false,
reading: false,
calledRead: false,
sync: true,
needReadable: false,
emittedReadable: false,
readableListening: false,
objectMode: true,
ranOut: false,
awaitDrain: 0,
readingMore: false,
decoder: null }
readable: true,
domain: null,
_events: {},
_maxListeners: 10,
_get: [Function] }
I get all the time this as result, even if the item exists or not.
