Important and breaking change change in nbc v1.13.0 for those using the pre-release version of ObjectStore functionality. Please read the release notes if using ObjectStore before upgrading.
Full Changelog: https://github.com/nats-io/nats.js/compare/v2.12.1...v2.13.0
Published by aricart over 1 year ago
NBC 1.12.1 enhances KV create entry to retry the operation and update the value if the previous value is a deleted key.
The objectstore API has requirements on ES ReadableStream and ES crypto. Previous releases of object store functionality relied on web-streams-polifill/ponyfill. This created issues for other downstream consumers. Starting with this release object store on node 16 or better will use built-in stream/web instead. Note that objectstore is not supported in node versions less than 16.

consumers.update()
. The ConsumerUpdateConfig
provides some introspection into fields that can be modified. Modifying a consumer is only supported on servers 2.6.4 or better. @aricart in https://github.com/nats-io/nats.deno/pull/229
streams.update()
now requires the name of the stream. The StreamUpdateConfig
provides some introspection into fields that can be modified. The previous API is shimmed, however, the shim will be removed on a future release. by @aricart in https://github.com/nats-io/nats.deno/pull/230 and https://github.com/nats-io/nats.deno/pull/235
keys()
now returns an iterator rather than a list of keys. If using the beta API you must change your code as no shim is possible by @aricart in https://github.com/nats-io/nats.deno/pull/240

This release contains a set of changes that are API-breaking for JetStream. Since the JetStream APIs on the JavaScript clients are Preview, only the minor version of the client has been bumped. Because of these changes, you should carefully read the Breaking Changes section to ensure you are not affected.
The Push Consumer Queue feature has changed. A new nats-server (2.4.0) has been released that modifies how this feature works.
The new JavaScript clients have been modified to work with the new server and will fail to work with an existing server using push consumers with queue groups.
Previously it was possible to create a push consumer and properly get it working in a queue group with a regular NatsConnection#subscribe
or NatsConnection#jetstream()#subscribe()
if all queue subscriptions used the same queue name and no plain (non-queue) subscriptions were used.
If the mix of subscriptions and queues referenced the same consumer but provided different queue names or no queue names, the delivery of messages was incorrect and could create conditions where some messages were seen in duplicate or have unexpected side effects.
The new nats-server changes will make an old consumer configuration with a queue group a noop - the server will not send messages to the client. To enable a queue group to work on a consumer:
deliver_group
matching the queue group name.The NATS client for JavaScript on 2.2.0 and beyond, enforces the above rules, so an Error is thrown from NatsConnection#jetstream().subscribe()
for configurations that try to use the queue group incorrectly.
Because an old server will not report deliver_group
for the consumer, any jetstream#subscribe()
that attempts to specify a queue group will fail the validation.
If you are creating your own NATS subscription to handle the consumer, and have an old server, you may continue to do that until you upgrade the server, at which point the nats-server will stop delivering messages to your client. Please ensure you don't use the consumer from different queue groups in the meantime.
This API has been removed (it was deprecated and printing console messages). To retrieve a message by its sequence,
replace with JetStreamManager#streams#getMessage({seq: number})
.
SequencePair
was renamed SequenceInfo
This matches changes in the server. These types are referenced from ConsumerInfo
.
[FIX] #441 - when Istio is booting, it is possible for the socket to close, triggering a catch(err) where the error is undefined - this fix simply aliases that as a connection refused error.
[FEAT] Added DeliveryPolicy#LastPerSubject
which allows a consumer to get the last message for each subject in a stream.
[FEAT] PubAck
now reports a domain
field representing the JetStream domain if set or returning an empty string. This feature requires a newer server.
[FIX] ConsumerConfig
now have fields deliver_group
