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.
