Inserts a single document into MongoDB. If documents passed in do not contain the _id field, one will be added to each of the documents missing it by the driver, mutating the document. This behavior can be overridden by setting the forceServerObjectId flag.
The document to insert
Inserts an array of documents into MongoDB. If documents passed in do not contain the _id field, one will be added to each of the documents missing it by the driver, mutating the document. This behavior can be overridden by setting the forceServerObjectId flag.
The documents to insert
Perform a bulkWrite operation without a fluent API
Legal operation types are
insertOnereplaceOneupdateOneupdateManydeleteOnedeleteManyPlease note that raw operations are no longer accepted as of driver version 4.0.
If documents passed in do not contain the _id field, one will be added to each of the documents missing it by the driver, mutating the document. This behavior can be overridden by setting the forceServerObjectId flag.

The filter used to select the document to update
The update operations to be applied to the document
Replace a document in a collection with another document
The filter used to select the document to replace
The Document that replaces the matching document
Update multiple documents in a collection

Delete a document from a collection
The filter used to select the document to remove

Rename the collection.
New name of of the collection.
Drop the collection from the database, removing it permanently. New accesses will create a new collection.
Fetches the first document that matches the filter
Creates a cursor for a filter that can be used to iterate over results from MongoDB
Returns the options of the collection.
Returns if the collection is a capped collection
Creates an index on the db and collection collection.
The field name or index specification to create an index for
Creates multiple indexes in the collection, this method is only supported for MongoDB 2.6 or higher. Earlier version of MongoDB will throw a command not supported error.
Note: Unlike {@link Collection#createIndex| createIndex}, this function takes in raw index specifications. Index specifications are defined here.
An array of index specifications to be created
Drops an index from this collection.
Name of the index to drop.
Drops all indexes from this collection.
Get the list of all indexes information for the collection.
Optional settings for the command
Checks if one or more indexes exist on the collection, fails on first non-existing index
One or more index names to check.
Retrieves this collections index info.
Gets an estimate of the count of documents in a collection using collection metadata. This will always run a count command on all server versions.
due to an oversight in versions 5.0.0-5.0.8 of MongoDB, the count command, which estimatedDocumentCount uses in its implementation, was not included in v1 of the Stable API, and so users of the Stable API with estimatedDocumentCount are recommended to upgrade their server version to 5.0.9+ or set apiStrict: false to avoid encountering errors.
Gets the number of documents matching the filter. For a fast count of the total documents in a collection see {@link Collection#estimatedDocumentCount| estimatedDocumentCount}. Note: When migrating from {@link Collection#count| count} to {@link Collection#countDocuments| countDocuments} the following query operators must be replaced:
| Operator | Replacement |
|---|---|
$where |
$expr |
$near |
$geoWithin with $center |
$nearSphere |
$geoWithin with $centerSphere |
The distinct command returns a list of distinct values for the given key across a collection.
Field of the document to find distinct values for

Get all the collection statistics.
Find a document and delete it in one atomic operation. Requires a write lock for the duration of the operation.

Execute an aggregation framework pipeline against the collection, needs MongoDB >= 2.2
An array of aggregation pipelines to execute
Optional settings for the command
Create a new Change Stream, watching for new changes (insertions, updates, replacements, deletions, and invalidations) in this collection.
Type of the data being detected by the change stream
Type of the whole change stream document emitted
An array of aggregation pipeline stages through which to pass change stream documents. This allows for filtering (using $match) and manipulating the change stream documents.
Optional settings for the command
Run Map Reduce across a collection. Be aware that the inline option for out will return an array of results not a collection.
The mapping function.
The reduce function.
Initiate an Out of order batch write operation. All operations will be buffered into insert/update/remove commands executed out of order.
Initiate an In order bulk write operation. Operations will be serially executed in the order they are added, creating a new operation for each switch in types.
Get the db scoped logger
Inserts a single document or a an array of documents into MongoDB. If documents passed in do not contain the _id field, one will be added to each of the documents missing it by the driver, mutating the document. This behavior can be overridden by setting the forceServerObjectId flag.
The documents to insert

An optional callback, a Promise will be returned if none is provided
Updates documents.

An optional callback, a Promise will be returned if none is provided
An estimated count of matching documents in the db to a filter.
NOTE: This method has been deprecated, since it does not provide an accurate count of the documents in a collection. To obtain an accurate count of documents in the collection, use {@link Collection#countDocuments| countDocuments}. To obtain an estimated count of all documents in the collection, use {@link Collection#estimatedDocumentCount| estimatedDocumentCount}.
