Compatibility

The Couchbase Node.js SDK aims to support LTS versions of Node.js. The table below indicates the Node.js SDK version where support of an LTS version of Node.js was added. Node.js versions that have reached their End-of-Life date are not supported.

In general, the SDK can be expected to run on all of the Operating Systems supported by Couchbase Server.

However, the Node.js SDK is tested and supported specifically on the following OSs and platforms:

Couchbase SDKs are developed to be run in an environment with local area network (LAN) like throughput and latencies. While there is no technical issue that prevents the use across a wide area network (WAN), SDKs have certain thresholds around timeouts and behaviors to recover that will not be the same once the higher latency and possible bandwidth constraints and congestion of a WAN is introduced. Couchbase tests for correctness under LAN like conditions. For this reason, only LAN-like network environments are officially supported.

Couchbase does document, for purposes of convenience when developing and performing basic operational work, what may need to be tuned when network throughputs and latencies are higher. If you encounter issues, even with these tunables, you should attempt the same workload from a supported, LAN-like environment.

The matrix below denotes the version of Couchbase Server, the version of the Node.js SDK and whether the SDK is:

Note the End of Life dates for Couchbase Server and SDK versions. See the notes there for Support details.

The Couchbase Node.js SDK is fully compatible with Couchbase Capella, our fully-hosted database-as-a-service. To make development easier, the SDK includes the Capella client certificate ready installed.

Note, Capella is offered as a fully provisioned service, so the underlying version of Couchbase Server changes over time. For this reason, compatibility information between Capella and the SDK is available on the Capella compatibility page.

Ottoman.js version 2.3.0 and above are compatible with Couchbase Node.js SDK 4.2.0 and above. Earlier versions of Ottoman ODM 2.x are only compatible with the 3.2 Node.js SDK.

This release of the SDK is written to version 3.6 of the SDK API specification (and matching the features available in Couchbase 7.6.2 and earlier). For most developers, just using the latest version will be all that matters, and few will need to look at another of our SDKs. Just for those few that do, the table below shows each Couchbase SDK release version that matches the API version (and a table that covers the earliest versions of the 3.x SDK API can be found in documentation for earlier versions of the SDK).

Whilst these two numbers match for the .NET and Ruby SDKs, this is not the case for the others, as version numbers for individual SDKs are bumped up in line with Semantic Versioning — check the release notes of each SDK for individual details.

SDK API 3.6: Introduced support for base 64 encoded vector types alongside Server 7.6.2 (and Capella). General Availability of our C++ SDK — now available as a supported, stand-alone SDK, this SDK is also the core of our Node.js, PHP, Python, and Ruby SDKs.

SDK API 3.5: Introduced support for Vector Search alongside Server 7.6 (and Capella). Adds scoped indexes to Search (for Vector Seach and traditional FTS). Read from Replica for Query and Sub-Doc operations. KV Range Scan for querying documents through the Data Service, even if you don’t know the document IDs (for use cases that require relatively low concurrency and tolerate relatively high latency). Transactions now implemented as a native library in all SDKs (except libcouchbase).

SDK API 3.4: Introduced support for ARM v8 on Ubuntu 20.04, Transactions on Spring Data Couchbase, and compatibility with running in serverless environments, such as AWS λ. The couchbase2:// connection string was introduced in Go 2.7, Java 3.5, Kotlin 1.2, and Scala 1.5, for Cloud Native Gateway with Couchbase Autonomous Operator (from CAO 2.6.1).

SDK API 3.3: Introduced alongside Couchbase Server 7.1, adds Management API for Eventing and Index Management for Scopes & Collections; extends Bucket Management API to support Custom Conflict Resolution and Storage Options; adds new platform support for Linux Alpine OS, Apple M1, and AWS Graviton2; provides improved error messages for better error handling; and an upgraded Spark Connector that runs on Spark 3.0 & 3.1 Platform.

SDK API 3.2: Introduced alongside Couchbase Server 7.0, provides features in support of Scopes and Collections, extends capabilities around Open Telemetry API to instrument telemetry data, enhanced client side field level encryption to add an additional layer of security to protect sensitive data, adds new platform support such as Ubuntu 20.04 LTS.

SDK API 3.1: Introduced alongside Couchbase Server 6.6, focuses on Bucket Management API, adds capabilities around Full Text Search features such-as Geo-Polygon support, Flex Index, and Scoring.

SDK API 3.0: Introduced alongside Couchbase Server 6.5, is a major overhaul from its predecessor, has simplified surface area, removed long-standing bugs and deprecated/removed old API, introduces new programming languages Scala and Ruby, written in anticipation to support Scopes and Collections.

Documentation on older, unsupported versions of the SDK — that have reached end-of-life — can be found in the archive.
