Properties

Optional authdb

authdb?: string

Optional autoIndexId

autoIndexId?: boolean

deprecated: Create an index on the _id field of the document. This option is deprecated in MongoDB 3.2+ and will be removed once no longer supported by the server.

Optional bsonRegExp

bsonRegExp?: boolean

return BSON regular expressions as BSONRegExp instances.

Optional capped

capped?: boolean

Create a capped collection

Optional changeStreamPreAndPostImages

changeStreamPreAndPostImages?: { enabled: boolean }

If set, enables pre-update and post-update document events to be included for any change streams that listen on this collection.

Type declaration

enabled: boolean

Optional checkKeys

checkKeys?: boolean

the serializer will check if keys are valid.

Optional clusteredIndex

clusteredIndex?: ClusteredCollectionOptions

A document specifying configuration options for clustered collections. For MongoDB 5.3 and above.

Optional collation

collation?: CollationOptions

Collation

Optional comment

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.

Optional dbName

dbName?: string

Optional enableUtf8Validation

enableUtf8Validation?: boolean

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

Optional encryptedFields

encryptedFields?: Document

experimental

Optional expireAfterSeconds

expireAfterSeconds?: number

The number of seconds after which a document in a timeseries or clustered collection expires.

Optional explain

explain?: ExplainVerbosityLike

Specifies the verbosity mode for the explain output.

Optional fieldsAsRaw

fieldsAsRaw?: Document

allow to specify if there what fields we wish to return as unserialized raw buffer.

Optional flags

flags?: number

Available for the MMAPv1 storage engine only to set the usePowerOf2Sizes and the noPadding flag

Optional fullResponse

fullResponse?: boolean

deprecated: This option does nothing

Optional ignoreUndefined

ignoreUndefined?: boolean

serialize will not emit undefined fields (default:true)

Optional indexOptionDefaults

indexOptionDefaults?: Document

Allows users to specify a default configuration for indexes when creating a collection

Optional max

max?: number

The maximum number of documents in the capped collection

Optional maxTimeMS

maxTimeMS?: number

Optional noResponse

noResponse?: boolean

Optional omitReadPreference

omitReadPreference?: boolean

Optional pipeline

pipeline?: Document[]

An array that consists of the aggregation pipeline stage. Creates the view by applying the specified pipeline to the viewOn collection or view

Optional pkFactory

pkFactory?: PkFactory

A primary key factory function for generation of custom _id keys.

Optional promoteBuffers

promoteBuffers?: boolean

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

Optional promoteLongs

promoteLongs?: boolean

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

Optional promoteValues

promoteValues?: boolean

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

Optional raw

raw?: boolean

Enabling the raw option will return a Node.js Buffer which is allocated using allocUnsafe API. See this section from the Node.js Docs here for more detail about what "unsafe" refers to in this context. If you need to maintain your own editable clone of the bytes returned for an extended life time of the process, it is recommended you allocate your own buffer and clone the contents:

example

const raw = await collection.findOne({}, { raw: true });
const myBuffer = Buffer.alloc(raw.byteLength);
myBuffer.set(raw, 0);
// Only save and use `myBuffer` beyond this point

remarks

Please note there is a known limitation where this option cannot be used at the MongoClient level (see NODE-3946). It does correctly work at Db, Collection, and per operation the same as other BSON options work.

Optional readConcern

readConcern?: ReadConcernLike

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

Optional readPreference

readPreference?: ReadPreferenceLike

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

Optional retryWrites

retryWrites?: boolean

Should retry failed writes

Optional serializeFunctions

serializeFunctions?: boolean

serialize the javascript functions (default:false).

Optional session

session?: ClientSession

Specify ClientSession for this command

Optional size

size?: number

The size of the capped collection in bytes

Optional storageEngine

storageEngine?: Document

Allows users to specify configuration to the storage engine on a per-collection basis when creating a collection

Optional strict

strict?: boolean

Returns an error if the collection does not exist

Optional timeseries

timeseries?: TimeSeriesCollectionOptions

A document specifying configuration options for timeseries collections.

Optional validationAction

validationAction?: string

Allows users to specify validation rules or expressions for the collection. For more information, see Document Validation

Optional viewOn

Optional willRetryWrite

willRetryWrite?: boolean

Optional writeConcern

writeConcern?: WriteConcern | WriteConcernSettings

Write Concern as an object
