CouchClient is the client SDK that enables accessing to the NoSQL document database Couchbase in Dart language.

CouchClient is distributed under the Apache 2.0 License.

Install from Dart Pub Repository

Add this to your pubspec.yaml (or create it):


Then run the Pub Package Manager (comes with the Dart SDK):

pub install

Install from Github for Bleeding Edge Stuff

To install stuff that is still in development, add this to your pubspec.yam:

    git: git://

For more information, please refer to Pub: Dependencies.


Using CouchClient is straightforward. Connect to the server and use the client's APIs to access the database.

import "dart:uri";
import "dart:convert";
import "dart:async";
import "package:couchclient/couchclient.dart";

void main() {
  // Connect to server per the provided Uris
  // Here assume your Couchbase Server is installed on localhost
  // Use "default" bucket with no password
  CouchClient.connect([Uri.parse("")], "default", "")
  // When client is ready, access the database
  .then((client) => access(client))
  // Catch all possible errors/exceptions
  .catchError((err) => print('Exception: $err'));

// The unique document id of the document
final String DOC_ID = "beer_Wrath";

// The Json encoded document
final String VALUE =
  '"updated":"2010-07-22 20:00:20",'
  '"description":"WRATH Belgian-style ",'
  '"style":"Other Belgian-Style Ales",'
  '"category":"Belgian and French Ale"}';

Future access(CouchClient client) {
  // Do a set
  return client.set(DOC_ID, UTF8.encode(VALUE))
  // Check if set succeeded and show message
  .then((ok) => print(ok ? "Set Succeeded" : "Set failed"))
  // Then get the value back by document id
  .then((_) => client.get(DOC_ID))
  // Check if get data equals to set one
  .then((val) => UTF8.decode( == VALUE)
  // Show message
  .then((ok) => print(ok ? "Get Succeeded" : "Get failed"))
  // Close the client
  .then((_) => client.close());

Test and Debug

You are welcome to submit bugs and feature requests. Or even better if you can fix or implement them!

If you'd like to contribute back to the core, you can fork this repository and send us a pull request, when it is ready.

Please be aware that one of CouchClient's design goals is to keep the sphere of API as neat and consistency as possible. Strong enhancement always demands greater consensus.
