FQL v4 will be decommissioned on June 30, 2025. Ensure that you complete your migration from FQL v4 to FQL v10 by that date.

Fauna accounts created after August 21, 2024 must use FQL v10. These accounts will not be able to run FQL v4 queries or access the v4 Dashboard.

For more details, see the v4 EOL announcement and migration guide. Contact support@fauna.com with any questions.

Current version and repository location

Current stable version

4.5.0

Repository

fauna/faunadb-jvm

Dependencies

Scala 2.11.x
Scala 2.12.x
Jackson for JSON parsing.

Installation

faunadb-scala/sbt:

libraryDependencies += ("com.faunadb" %% "faunadb-scala" % "4.5.0")

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

Navigate to the Fauna Dashboard

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

Click NEW DATABASE and select your Region Group.
Create a new collection

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

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" % "4.5.0"
  )

Create a local application file

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