For example, 5ddf203 stops us from understanding $sets and $unsets with empty field parts, but pre-2.6 MongoDB could generate them. (And even post-2.6 may be able to generate $unsets with bad field names, but it's not important for us to match that behavior since with Minimongo you shouldn't be able to put them in in the first place.)
mongo
The mongo package is a full stack database
driver that provides
several paramount pieces of functionality to work with MongoDB in
Meteor:
- an efficient Livequery implementation providing real-time updates from the database by consuming the MongoDB replication log
- a fall-back Livequery implementation for cases when the replication log is not available, implemented by polling the database
- DDP RPC end-points for updating the data from clients connected over the wire
- Serialization and deserialization of updates to the DDP format
To learn more about Livequery, see the project page on www.meteor.com.
Direct access to npm mongodb API
On the server, the mongo package is implemented using the
npm mongodb module. If you'd like
direct access to this module, you can find it at
MongoInternals.NpmModules.mongodb.module. Its version can be read at
MongoInternals.NpmModules.mongodb.version.
Additionally, you can call c.rawCollection() or c.rawDatabase() on any
Mongo.Collection to get the object from the npm mongodb module corresponding
to the collection or database. This is documented at
http://mongodb.github.io/node-mongodb-native/
The version of mongo used may change incompatibly from version to version of
Meteor (or we may even replace it with an entirely different implementation);
use at your own risk.
