Version CI

This is a SDK to access a Couchbase Server cluster from Dart.

⚠️ This project is still at an early stage and a work in progress. If you find bugs or have suggestions for improvements please open an issue.

Couchbase Server is a document-oriented NoSQL database that is distributed, scalable, and highly available. It is a key-value store with additional support for documents, views, and queries.


Add a dependency on couchbase to your pubspec.yaml file:

dart pub add couchbase

The SDK uses a native library that is platform specific and is automatically downloaded when you use the SDK. The native library can be downloaded manually by running the following command:

dart run couchbase:install

This is useful when a Dart application is packaged as a Docker image and you want to avoid the latency of downloading the native library each time a container is created. In this case the native library should be included in the image.

Getting started

Use Cluster.connect to connect to a Couchbase Server cluster:

import 'package:couchbase/couchbase.dart';

void main() async {
  final cluster = await Cluster.connect(
      username: 'admin',
      password: 'password',

  final bucket = cluster.bucket('my-bucket');
  final collection = bucket.defaultCollection;

  await collection.insert('greeting-alice', {'message': 'Hello @name!', 'name': 'Alice'});

  final getResult = await collection.get('greeting-alice');

  await cluster.close();
