Release notes Package name: mongodb
The MongoDB Node.js team is pleased to announce version 6.7.0 of the mongodb package!
Release Notes
Support for MONGODB-OIDC Authentication
MONGODB-OIDC is now supported as an authentication mechanism for MongoDB server versions 7.0+. The currently supported facets to authenticate with are callback authentication, human interaction callback authentication, Azure machine authentication, and GCP machine authentication.
Azure Machine Authentication
The MongoClient must be instantiated with authMechanism=MONGODB-OIDC in the URI or in the client options. Additional required auth mechanism properties of TOKEN_RESOURCE and ENVIRONMENT are required and another optional username can be provided. Example:
The MongoClient must be instantiated with authMechanism=MONGODB-OIDC in the URI or in the client options. Additional required auth mechanism properties of TOKEN_RESOURCE and ENVIRONMENT are required. Example:
The user can provide a custom callback to the MongoClient that returns a valid response with an access token. The callback is provided as an auth mechanism property an has the signature of:
constoidcCallBack=(params: OIDCCallbackParams): Promise<OIDCResponse>=>{// params.timeoutContext is an AbortSignal that will abort after 30 seconds for non-human and 5 minutes for human.// params.version is the current OIDC API version.// params.idpInfo is the IdP info returned from the server.// params.username is the optional username.// Make a call to get a token.consttoken= ...;return{accessToken: token,expiresInSeconds: 300,refreshToken: token};}constclient=newMongoClient('mongodb+srv://<host>:<port>/?authMechanism=MONGODB-OIDC',{authMechanismProperties: {OIDC_CALLBACK: oidcCallback}});awaitclient.connect();
For callbacks that require human interaction, set the callback to the OIDC_HUMAN_CALLBACK property:
Fixed error when useBigInt64=true was set on Db or MongoClient
Fixed an issue where when setting useBigInt64=true on MongoClients or Dbs an internal function compareTopologyVersion would throw an error when encountering a bigint value.
The MongoDB Node.js team is pleased to announce version 6.6.2 of the mongodb package!
Release Notes
Server Selection performance regression due to incorrect RTT measurement
Starting in version 6.6.0, when using the stream server monitoring mode, heartbeats were incorrectly timed as having a duration of 0, leading to server selection viewing each server as equally desirable for selection.
The MongoDB Node.js team is pleased to announce version 6.6.1 of the mongodb package!
Release Notes
ref()-ed timer keeps event loop running until client.connect() resolves
When the MongoClient is first starting up (client.connect()) monitoring connections begin the process of discovering servers to make them selectable. The ref()-edserverSelectionTimeoutMS timer keeps Node.js' event loop running as the monitoring connections are created. In the last release we inadvertently unref()-ed this initial timer which would allow Node.js to close before the monitors could create connections.
The MongoDB Node.js team is pleased to announce version 6.6.0 of the mongodb package!
Release Notes
Aggregation pipelines can now add stages manually
When creating an aggregation pipeline cursor, a new generic method addStage() has been added in the fluid API for users to add aggregation pipeline stages in a general manner.
cause and package name included for MongoMissingDependencyErrors
MongoMissingDependencyErrors now include a cause and a dependencyName field, which can be used to programmatically determine which package is missing and why the driver failed to load it.
For example:
MongoMissingDependencyError: The iHateJavascript module does not exist
at findOne (mongodb/main.js:7:11)
at Object.<anonymous> (mongodb/main.js:14:1)
... 3 lines matching cause stack trace ...
at Module._load (node:internal/modules/cjs/loader:1021:12) {
dependencyName: 'iHateJavascript',
[Symbol(errorLabels)]: Set(0) {},
[cause]: Error: Cannot find module 'iHateJavascript'
Require stack:
- mongodb/main.js
at require (node:internal/modules/helpers:179:18)
at findOne (mongodb/main.js:5:5)
at Object.<anonymous> (mongodb/main.js:14:1) {
code: 'MODULE_NOT_FOUND',
requireStack: [ 'mongodb/main.js' ]
}
}
ServerDescription Round Trip Time (RTT) measurement changes
(1) ServerDescription.roundTripTime is now a moving average
Previously, ServerDescription.roundTripTime was calculated as a weighted average of the most recently observed heartbeat duration and the previous duration. This update changes this behaviour to average ServerDescription.roundTripTime over the last 10 observed heartbeats. This should reduce the likelihood that the selected server changes as a result of momentary spikes in server latency.
(2) Added minRoundTripTime to ServerDescription
A new minRoundTripTime property is now available on the ServerDescription class which gives the minimum RTT over the last 10 heartbeats. Note that this value will be reported as 0 when fewer than 2 samples have been observed.
constindexName=awaitcollection.createSearchIndex({name: 'my-vector-search-index',// new! specifies that a `vectorSearch` index is createdtype: 'vectorSearch',definition: {mappings: {dynamic: false}}});
Collection.findOneAndModify's UpdateFilter.$currentDate no longer throws on collections with limited schema
Example:
// collection has no schemacollection.update($currentData: {lastModified: true}// no longer throws a TS error);
TopologyDescription now properly stringifies itself to JSON
The TopologyDescription class is exposed by the driver in server selection errors and topology monitoring events to provide insight into the driver's current representation of the server's topology and to aid in debugging. However, the TopologyDescription uses Maps internally, which get serialized to {} when JSON stringified. We recommend using Node's util.inspect() helper to print topology descriptions because inspect properly handles all JS types and all types we use in the driver. However, if JSON must be used, the TopologyDescription now provides a custom toJSON() hook:
client.on('topologyDescriptionChanged',({ newDescription })=>{// recommended!console.log('topology description changed',inspect(newDescription,{depth: Infinity,colors: true}))// now properly prints the entire topology descriptionconsole.log('topology description changed',JSON.stringify(newDescription))});
Omit readConcern and writeConcern in Collection.listSearchIndexes options argument
Important
readConcern and writeConcern are no longer viable keys in the options argument passed into Collection.listSearchIndexes
This type change is a correctness fix.
Collection.listSearchIndexes is an Atlas specific method, and Atlas' search indexes do not support readConcern and writeConcern options. The types for this function now reflect this functionality.
Don't throw error when non-read operation in a transaction has a ReadPreferenceMode other than 'primary'
The following error will now only be thrown when a user provides a ReadPreferenceMode other than primary and then tries to perform a command that involves a read:
newMongoTransactionError('Read preference in a transaction must be primary');
Prior to this change, the Node Driver would incorrectly throw this error even when the operation does not perform a read.
Note: a RunCommandOperation is treated as a read operation for this error.
TopologyDescription.error type is MongoError
Important
The TopologyDescription.error property type is now MongoError rather than MongoServerError.
This type change is a correctness fix.
Before this change, the following errors that were not instances of MongoServerError were already passed into TopologyDescription.error at runtime:
MongoError with a MongoErrorLabel.HandshakeError label
indexExists() no longer supports the full option
The Collection.indexExists() helper supported an option, full, that modified the internals of the method. When full was set to true, the driver would always return false, regardless of whether or not the index exists.
The full option is intended to modify the return type of index enumeration APIs (Collection.indexes() and Collection.indexInformation(), but since the return type of Collection.indexExists() this option does not make sense for the Collection.indexExists() helper.
We have removed support for this option.
indexExists(), indexes() and indexInformation() support cursor options in Typescript
These APIs have supported cursor options at runtime since the 4.x version of the driver, but our Typescript has incorrectly omitted cursor options from these APIs.
Index information helpers have accurate Typescript return types
Collection.indexInformation(), Collection.indexes() and Db.indexInformation() are helpers that return index information for a given collection or database. These helpers take an option, full, that configures whether the return value contains full index descriptions or a compact summary:
collection.indexes({full: true});// returns an array of index descriptionscollection.indexes({full: false});// returns an object, mapping index names to index keys
However, the Typescript return type of these helpers was always Document. Thanks to @ prenaissance, these helpers now have accurate type information! The helpers return a new type, IndexDescriptionCompact | IndexDescriptionInfo[], which accurately reflects the return type of these helpers. The helpers also support type narrowing by providing a boolean literal as an option to the API:
collection.indexes();// returns IndexDescriptionCompact | IndexDescriptionInfo[]collection.indexes({full: false});// returns an IndexDescriptionCompactcollection.indexes({full: true});// returns an IndexDescriptionInfo[]
collection.indexInfo();// returns IndexDescriptionCompact | IndexDescriptionInfo[]collection.indexInfo({full: false});// returns an IndexDescriptionCompactcollection.indexInfo({full: true});// returns an IndexDescriptionInfo[]
db.indexInfo();// returns IndexDescriptionCompact | IndexDescriptionInfo[]db.indexInfo({full: false});// returns an IndexDescriptionCompactdb.indexInfo({full: true});// returns an IndexDescriptionInfo[]
AWS credentials with expirations no longer throw when using on-demand AWS KMS credentials
In addition to letting users provide KMS credentials manually, client-side encryption supports fetching AWS KMS credentials on-demand using the AWS SDK. However, AWS credential mechanisms that returned access keys with expiration timestamps caused the driver to throw an error.
The driver will no longer throw an error when receiving an expiration token from the AWS SDK.
ClusterTime interface signature optionality
The ClusterTime interface incorrectly reported the signature field as required, the server may omit it, so the typescript has been updated to reflect reality.

Release Notes
Bulk Write Operations Generate Ids using pkFactory
When performing inserts, the driver automatically generates _ids for each document if there is no _id present. By default, the driver generates ObjectIds. An option, pkFactory, can be used to configure the driver to generate _ids that are not object ids.
For a long time, only Collection.insert and Collection.insertMany actually used the pkFactory, if configured. Notably, Collection.bulkWrite(), Collection.initializeOrderedBulkOp() and Collection.initializeOrderedBulkOp()always generated ObjectIds, regardless of what was configured on collection.
The driver always generates _ids for inserted documents using the pkFactory.
Caution
If you are using a pkFactory and performing bulk writes, you may have inserted data into your database that does not have _ids generated by the pkFactory.
Fixed applying read preference to commands depending on topology
When connecting to a secondary in a replica set with a direct connection, if a read operation is performed, the driver attaches a read preference of primaryPreferred to the command.
Fixed memory leak in Connection layer
The Connection class has recently been refactored to operate on our socket operations using promises. An oversight how we made async network operations interruptible made new promises for every operation. We've simplified the approach and corrected the leak.
Query SRV and TXT records in parallel
When connecting using a convenient SRV connection string (mongodb+srv://) hostnames are obtained from an SRV dns lookup and some configuration options are obtained from a TXT dns query. Those DNS operations are now performed in parallel to reduce first-time connection latency.
Container and Kubernetes Awareness
The Node.js driver now keeps track of container metadata in the client.env.container field of the handshake document.
If space allows, the following metadata will be included in client.env.container:
env?: {
container?: {
orchestrator?: 'kubernetes' // if process.env.KUBERNETES_SERVICE_HOST is set
runtime?: 'docker' // if the '/.dockerenv' file exists
}
}
Note: If neither Kubernetes nor Docker is present, client.env will not have the container property.
Add property errorResponse to MongoServerError
The MongoServer error maps keys from the error document returned by the server on to itself. There are some use cases where the original error document is desirable to obtain in isolation. So now, the mongoServerError.errorResponse property stores a reference to the error document returned by the server.
Deprecated unused CloseOptions interface
The CloseOptions interface was unintentionally made public and was only intended for use in the driver's internals. Due to recent refactoring (NODE-5915), this interface is no longer used in the driver. Since it was marked public, out of an abundance of caution we will not be removing it outside of a major version, but we have deprecated it and will be removing it in the next major version.
The MongoDB Node.js team is pleased to announce version 6.4.0 of the mongodb package!
Release Notes
Server selection will use a different Mongos on retry
When retrying reads or writes on a sharded cluster, the driver will attempt to select a different mongos for the retry if multiple are present. This should heuristically avoid encountering the original error that caused the need to retry the operation.
Caching AWS credentials provider per client
Instead of creating a new AWS provider for each authentication, we cache the AWS credentials provider per client to prevent overwhelming the auth endpoint and ensure that cached credentials are not shared with other clients.
BSON upgraded to ^6.4.0
BSON has had a number of performance increases in the last two releases (6.3.0 and 6.4.0). Small basic latin (ASCII) only strings, small memory allocations (ObjectId and Decimal128) and numeric parsing operations (int32, doubles, and longs) have all had optimizations applied to them.
ExceededTimeLimit was made a retryable reads error
Read operations will be retried after receiving an error with the ExceededTimeLimit label.
Fixed unresolved request issue in KMS requester
Internal to the field-level encryption machinery is a helper that opens a TLS socket to the KMS provider endpoint and submits a KMS request. The code neglected to add a 'close' event listener to the socket, which had the potential to improperly leave the promise pending indefinitely if no error was encountered.
The base64 padding is now preserved in the saslContinue command
The authentication was rejected by the saslContinue command from mongosh due to missing "=" padding from the client. We fixed the way we parse payload to preserve trailing "="s.
countDocuments now types the filter using the collection Schema
Previously, countDocuments had a weakly typed Document type for the filter allowing any JS object as input. The filter is now typed as Filter<Schema> to enable autocompletion, and, hopefully, catch minor bugs.
Thank you to @ pashok88895 for contributing to this improvement.

Previously the following code sample would show a type error:
