Properties

allowDiskUse?: boolean

allowDiskUse lets the server know if it can use disk to store temporary results for the aggregation (requires mongodb 2.6 >).

authdb?: string
awaitData?: boolean

If awaitData is set to true, when the cursor reaches the end of the capped collection, MongoDB blocks the query thread for a period of time waiting for new data to arrive. When new data is inserted into the capped collection, the blocked thread is signaled to wake up and return the next batch to the client.

batchSize?: number

Specifies the number of documents to return in each response from MongoDB

bsonRegExp?: boolean

return BSON regular expressions as BSONRegExp instances.

bypassDocumentValidation?: boolean

Allow driver to bypass schema validation in MongoDB 3.2 or higher.

checkKeys?: boolean

the serializer will check if keys are valid.

collation?: CollationOptions

Specify collation.

comment?: unknown

Comment to apply to the operation.

In server versions pre-4.4, 'comment' must be string. A server error will be thrown if any other type is provided.

In server versions 4.4 and above, 'comment' can be any valid BSON type.

cursor?: Document

Return the query as cursor, on 2.6 > it returns as a real cursor on pre 2.6 it returns as an emulated cursor.

dbName?: string
enableUtf8Validation?: boolean

Enable utf8 validation when deserializing BSON documents. Defaults to true.

Specifies the verbosity mode for the explain output.

fieldsAsRaw?: Document

ignoreUndefined?: boolean

serialize will not emit undefined fields (default:true)

let?: Document

Map of parameter names and values that can be accessed using $$var (requires MongoDB 5.0).

maxAwaitTimeMS?: number

When applicable maxAwaitTimeMS controls the amount of time subsequent getMores that a cursor uses to fetch more data should take. (ex. cursor.next())

maxTimeMS?: number

When applicable maxTimeMS controls the amount of time the initial command that constructs a cursor should take. (ex. find, aggregate, listCollections)

noCursorTimeout?: boolean
noResponse?: boolean
omitReadPreference?: boolean
out?: string
promoteBuffers?: boolean

when deserializing a Binary will return it as a node.js Buffer instance.

promoteLongs?: boolean

when deserializing a Long will fit it into a Number if it's smaller than 53 bits

promoteValues?: boolean

when deserializing will promote BSON values to their Node.js closest equivalent types.

raw?: boolean

Return BSON filled buffers from operations

readConcern?: ReadConcernLike

Specify a read concern and level for the collection. (only MongoDB 3.2 or higher supported)

readPreference?: ReadPreferenceLike

The preferred read preference (ReadPreference.primary, ReadPreference.primary_preferred, ReadPreference.secondary, ReadPreference.secondary_preferred, ReadPreference.nearest).

retryWrites?: boolean

Should retry failed writes

serializeFunctions?: boolean

serialize the javascript functions (default:false).

session?: ClientSession

Specify ClientSession for this command

tailable?: boolean

By default, MongoDB will automatically close a cursor when the client has exhausted all results in the cursor. However, for capped collections you may use a Tailable Cursor that remains open after the client exhausts the results in the initial cursor.
