Scala

This section is intended to help Scala developers get started using the Fauna Scala driver for application development.

Current version and repository location

Current stable version

4.3.0

Repository

Dependencies

  • Scala 2.11.x

  • Scala 2.12.x

  • Jackson for JSON parsing.

Installation

faunadb-scala/sbt:
libraryDependencies += ("com.faunadb" %% "faunadb-scala" % "4.3.0")

Example application

The following example code runs a bare-bones Scala application which creates a new document in a

collection called People.

Prerequisites

  • A Fauna account. If you don’t have one, see the dashboard quick start for help getting set up.

  • A supported version of Scala and the Fauna Scala driver.

  • sbt, version 1.4 or higher.

Procedure

  1. Navigate to the Fauna Dashboard

    Log in to your Fauna account at Fauna Dashboard if you’re not already logged in.

  2. Create a new database

    Click NEW DATABASE and select your Region Group.

  3. Create a new collection

    Click NEW COLLECTION. Name your new collection People and save it.

  4. Create an access key

    Click SECURITY in the left-side navigation menu. Create a new key for your database. Be sure to save the key’s secret in a safe place, as it is only displayed once.

  5. Create a local environment variable with your access key’s secret

    On MacOS and Linux systems, enter the following in a terminal window:

    export FAUNADB_SECRET=<your-secret>

    For Windows systems, enter the following in a terminal window:

    set FAUNADB_SECRET=<your secret>

    For either example, replace <your secret> with the secret for the access key that you created.

  6. Create a project folder using the standard directory layout

    In a terminal window, in an empty folder, run the following command:

    sbt new scala/hello-world.g8

    When prompted, name the project example.

    Then enter the folder:

    cd example
  7. Edit the build.sbt file

    With your preferred editor, replace the contents of the build.sbt file with the following:

    ThisBuild / scalaVersion := "2.12.15"
    ThisBuild / version := "0.1.0"
    ThisBuild / organization := "com.example"
    ThisBuild / organizationName := "example"
    ThisBuild / showSuccess := false
    
    lazy val root = (project in file("."))
      .settings(
        name := "example",
        libraryDependencies += "org.slf4j" % "slf4j-nop" % "1.7.28",
        libraryDependencies += "com.faunadb" %% "faunadb-scala" % "4.3.0"
      )
  8. Create a local application file

    With your preferred editor, replace the contents of the src/main/scala/Main.scala file with the following code:

  9. Compile and run the application

    sbt run

    You should see results similar to this:

    If you get an error, check to make sure that the secret for your access key is correct.
