This is a library for accessing Couchbase in Scala.
couchbase-scala is published to maven center
- using typesafe config file application.conf
to config couchbase connection url, buckets, timeout,..
see reference.conf
com.couchbase.timeout {
connect=10s
# ...
}
com.sandinh.couchbase {
connectionString = "dev.sandinh.com"
user="?"
password="?"
}
- load the config, instantiate a CBCluster instance, then open a bucket
import com.typesafe.config.ConfigFactory
import com.sandinh.couchbase.CBCluster
val cluster = new CBCluster(ConfigFactory.load())
val accBucket = cluster.bucket("acc")
Or, you can use DI (example google guice):
class CBModule extends AbstractModule {
override def configure(): Unit = {
bind(classOf[Config]).toInstance(ConfigFactory.load())
}
}
class MyClient @Inject() (cluster: CBCluster) {
val accBucket = cluster.bucket("acc")
}
- access couchbase using CBBucket's api
val r: Future[GetResult] = accBucket.get("some_key")
val s = accBucket.getT[String]("some_key")
//see other methods (upsert, insert, replace, remove, touch, counter, append, unlock, getFromReplica, getAndLock,..)
//from CBBucket class
- you can use play-json to retrieve a JsValue directly
import play.api.libs.json.{Json, Format}
import com.sandinh.couchbase.Implicits.jsonSerializer // Used in upsert
case class Acc(name: String, gender: Option[Boolean])
object Acc {
implicit val fmt: OFormat[Acc] = Json.format[Acc]
}
accBucket.upsert("some_key", Acc("name", None))
val name = accBucket.getJsT[Acc]("some_key").map(_.name)
see CHANGES.md
- prepare couchbase for testing
docker run -d --name cb -p 8091-8094:8091-8094 -p 11210:11210 couchbase:5.0.1
docker cp travis-cb-prepare.sh cb:/tmp
docker exec -i cb /tmp/travis-cb-prepare.sh
or, if you have prepared before => only run docker start cb
test
We use sd-devops so:
- Every push (or merge a PR) to
master
branch will be publish to sonatype snapshots (only if QA, test, compatible check pass) - If push tag match glob
v[0-9]*
, exv9.0.0
or evenv9bla.bla
then publish job will publish a release version to sonatype release repo (which will be sync to maven central) - !!!NOTE!!! You MUST tag version with v prefix or else it will not be published!
- You should never manually publish from your local machine unless
sbt publishLocal
- MUST update [CHANGES.md]!
