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. |
Scala
This section is intended to help Scala developers get started using the Fauna Scala driver for application development.
Dependencies
-
Scala 2.11.x
-
Scala 2.12.x
-
Jackson for JSON parsing.
Installation
faunadb-scala/sbt
:libraryDependencies += ("com.faunadb" %% "faunadb-scala" % "0.1.0-M4")
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
fileWith 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" % "0.1.0-M4" )
-
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.
