Finagle Postgres

Build status Maven Central Join the chat at https://gitter.im/finagle/finagle-postgres

This library provides PostgreSQL database support for Finagle.

Documentation

See the GitHub Pages

Using the Postgres client

Installation

Finagle Postgres is published on Maven Central. Use the following sbt snippet to bring it as a dependency.

libraryDependencies ++= Seq(
  "io.github.finagle" %% "finagle-postgres" % "0.12.0"
)

Connecting to the DB

val client = Postgres.Client()
  .withCredentials("user", Some("password"))
  .database("dbname")
  .withSessionPool.maxSize(1) //optional; default is unbounded
  .withBinaryResults(true)
  .withBinaryParams(true)
  .withTransport.tls("host")
  .newRichClient("host:port")

Selecting with simple query

val f = client.select("select * from users") {row =>
    User(row.getString("email"), row.getString("name"))
}
logger.debug("Responded " + Await.result(f))

Integration Tests

sbt test won't run integration tests by default. In order to make it easier for development, a database environment is provided via Docker. After installing Docker and docker compose, run:

docker-compose up -d

A few environment variables need to be provided as well:

export PG_HOST_PORT=localhost:5432 PG_DBNAME=finagle_postgres_test PG_USER=postgres

With the database and variables in place, all tests will be executed. More details in IntegrationSpec
