Properties

Properties

Optional allowDiskUse

allowDiskUse?: boolean

Allows disk use for blocking sort operations exceeding 100MB memory. (MongoDB 3.2 or higher)

Optional allowPartialResults

allowPartialResults?: boolean

For queries against a sharded collection, allows the command (or subsequent getMore commands) to return partial results, rather than an error, if one or more queried shards are unavailable.

Optional authdb

authdb?: string

Optional awaitData

awaitData?: boolean

Specify if the cursor is a tailable-await cursor. Requires tailable to be true

Optional batchSize

batchSize?: number

Set the batchSize for the getMoreCommand when iterating over the query results.

Optional bsonRegExp

bsonRegExp?: boolean

return BSON regular expressions as BSONRegExp instances.

Optional checkKeys

checkKeys?: boolean

the serializer will check if keys are valid.

Optional collation

collation?: CollationOptions

Specify collation (MongoDB 3.4 or higher) settings for update operation (see 3.4 documentation for available fields).

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 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 hint

hint?: Hint

Tell the query to use specific indexes in the query. Object of indexes to use, {'_id':1}

Optional ignoreUndefined

ignoreUndefined?: boolean

serialize will not emit undefined fields (default:true)

Optional let

let?: Document

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

Optional limit

limit?: number

Sets the limit of documents returned in the query.

Optional max

max?: Document

The exclusive upper bound for a specific index

Optional maxAwaitTimeMS

maxAwaitTimeMS?: number

The maximum amount of time for the server to wait on new documents to satisfy a tailable cursor query. Requires tailable and awaitData to be true

Optional maxTimeMS

maxTimeMS?: number

Number of milliseconds to wait before aborting the query.

Optional min

min?: Document

The inclusive lower bound for a specific index

Optional noCursorTimeout

noCursorTimeout?: boolean

The server normally times out idle cursors after an inactivity period (10 minutes) to prevent excess memory use. Set this option to prevent that.

Optional noResponse

noResponse?: boolean

Optional omitReadPreference

omitReadPreference?: boolean

Optional oplogReplay

oplogReplay?: boolean

Option to enable an optimized code path for queries looking for a particular range of ts values in the oplog. Requires tailable to be true.

deprecated

Starting from MongoDB 4.4 this flag is not needed and will be ignored.

Optional projection

projection?: Document

The fields to return in the query. Object of fields to either include or exclude (one of, not both), {'a':1, 'b': 1} or {'a': 0, 'b': 0}

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 returnKey

returnKey?: boolean

If true, returns only the index keys in the resulting documents.

Optional serializeFunctions

serializeFunctions?: boolean

serialize the javascript functions (default:false).

Optional session

session?: ClientSession

Specify ClientSession for this command

Optional showRecordId

showRecordId?: boolean

Determines whether to return the record identifier for each document. If true, adds a field $recordId to the returned documents.

Optional singleBatch

singleBatch?: boolean

Determines whether to close the cursor after the first batch. Defaults to false.

Optional skip

skip?: number

Set to skip N documents ahead in your query (useful for pagination).

Optional sort

sort?: Sort

Set to sort the documents coming back from the query. Array of indexes, [['a', 1]] etc.

Optional tailable

tailable?: boolean

Specify if the cursor is tailable.

Optional timeout

timeout?: boolean

Specify if the cursor can timeout.

Optional willRetryWrite

willRetryWrite?: boolean

Optional writeConcern

writeConcern?: WriteConcern | WriteConcernSettings

Write Concern as an object
