Thanks so much for show. But returns this output: 'collection found [object Object] ".
Here is a fix:

      ...
      names.map(function(item) {
        console.log('found collection %s', item.name);
      });
      ...

Use util.inspect and tell me what it says …. Best, ## Edward Hotchkiss [email protected] 415.205.0006 / @Stricttype ## http://edwardhotchkiss.com/

Code:

console.log(util.inspect(item));

Output: (2 items in mongodb - mongodb://localhost/test)
{ name: 'test.threads' }
{ name: 'test.system.indexes' }

Versions:

• mongodb: 2.0.4
• nodejs: 0.6.14

Yes there is.

Mongodb in MONGO term. returns an array of strings:

Db.getCollectionNames ()
["System.indexes", "threads"]

In node script return:

console.log(util.inspect(names)); => [ { name: 'test.threads' }, { name: 'test.system.indexes' } ]

Once more many thanks for your show. Take care.

mongoose.connection.on('open', function (ref) { mongoose.connection.db.collections(function(error, collections) { if (error) { throw new Error(error); } else { collections.map(function(collection) { console.log('found collection %s', collection.s.name); }); } });

is the new name now listCollections ?
