Introduction to minimongo

minimongo is an in-memory data store that’s present on the client-side. It’s a front-end implementation of MongoDB using JavaScript that serves as a cache for storing a subset of data that the client works with.

When we query for data from the client, this data is served from the local cache without making a round trip to the server. We can query the data stored in minimongo by using the same query operators as MongoDB.

In the diagram above, a created Mongo collection exists on both the server and the client. This is a core principle of Meteor, namely the existence of a database on both the server and client side.
