Build Status

This is a library for accessing Couchbase in Scala.


couchbase-scala is published to maven center

  1. using typesafe config file application.conf to config couchbase connection url, buckets, timeout,..
# see class com.couchbase.client.java.env.DefaultCouchbaseEnvironment
com.couchbase.timeout {
com.sandinh.couchbase {
  connectionString = "couchbase://dev.sandinh.com"
  buckets {
    # syntax: bucketName.password=".."
    # we will use CBCluster.openBucket(bucketName) to retrieve a ScalaBucket object
    # we can also use the following verbose syntax to customize the real bucket name when connect to couchbase server
    bk1 {
      name = fodi
  1. load the config, instantiate a CBCluster instance, then open a bucket
val config = ConfigFactory.load()
val cluster = new CBCluster(config);
val accBucket = cluster.openBucket("acc");

Or, you can use DI (example google guice):

class CBModule extends AbstractModule {
  override def configure(): Unit = {

class MyClient @Inject() (cluster: CBCluster) {
  val accBucket = cluster.openBucket("acc");
  1. access couchbase using ScalaBucket's api
val s = accBucket.get[StringDocument]("some_key").map(_.content)
val s = accBucket.getT[String]("some_key")
val s = accBucket.getOrElseT("some_key")("default value")
//see other methods (insert, replace, remove, touch, counter, append, unlock, getFromReplica, getAndLock,..)
//from ScalaBucket class
  1. you can use play-json to retrieve a JsValue directly
case class Acc(name: String, gender: Option[Boolean])
object Acc { implicit val fmt = Json.format[Acc] }
val name = accBucket.getJsT[Acc]("some_key").map(_.name)
