Mongoose Model API

Mongoose's model API provides tools for working with predefined Mongoose Model's. It's the primary API that you will use to manipulate documents in MongoDB:

Property	Example	Description
remove	Posts.remove({title: 'foobar'});	Removes matching documents from the db.
aggregate	Posts.aggregate() .group({}) .select({});	Performs data aggregations on the models collection.
bulkWrite	Posts.bulkWrite([{ insertOne: {} }, { updateOne: {} }, { deleteOne: {} }]);	Combines multiple create, update, and delete operations into a single MongoDB request.
count	Posts.count({});	Retrieves the count of items that match.
create	Posts.create(new Post({}));	Creates and saves one or more documents passed to it.
deleteMany	Posts.deleteMany({}); ...
