# Quarkus Couchbase

Integrates Couchbase into Quarkus.

This extension is currently in beta status. It supports:

• Dependency injecting a Couchbase Cluster.
• Configuring the Cluster through application.properties. Currently, a minimal set of configuration options is provided.
• A dev service that starts a Couchbase server in a Docker container. With this you can develop your Quarkus app without having to install Couchbase on your machine.

Please try it out and provide feedback, ideas and bug reports on Github.

Native Image

[!IMPORTANT] While the extension compiles natively, there are known issues with the produced runner which we are actively working to resolve.

Usage

Add it to your project:

<dependency>
  <groupId>io.quarkiverse.couchbase</groupId>
  <artifactId>quarkus-couchbase</artifactId>
  <version>1.0.0.Beta2</version>
</dependency>

Provide the Couchbase configuration in application.properties:

quarkus.couchbase.connection-string=localhost
quarkus.couchbase.username=username
quarkus.couchbase.password=password

To disable TestContainers, add:

quarkus.devservices.enabled=false

Now you can @Inject a Couchbase Cluster into your project:

@Path("/couchbase")
public class TestCouchbaseResource {
    @Inject
    Cluster cluster;

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    @Path("/test")
    public String run() {
        // Get a reference to a particular Couchbase bucket and its default collection
        var bucket = cluster.bucket("travel-sample");
        var collection = bucket.defaultCollection() ;

        // Upsert a new document
        collection.upsert("test", JsonObject.create().put("foo", "bar"));

        // Fetch and print a document
        var doc = bucket.defaultCollection().get("test");
        System.out.println("Got doc " + doc.contentAsObject().toString());

        // Perform a N1QL query
        var queryResult = cluster.query("select * from `travel-sample` where url like 'http://marriot%' and country = 'United States';");

        queryResult.rowsAsObject().forEach(row -> {
            System.out.println(row.toString());
        });

        return "success!";
    }
}

And test http://localhost:8080/couchbase/test.

Limitations

In this a beta release the configuration options are limited to the three shown above.
This means that a Couchbase cluster configured securely and requiring TLS or a client or server certificate, cannot currently be connected to.
