Scala-Forklift helps manage and apply database migrations for your Scala project.

Write your migrations in plain SQL:

MyMigrations.migrations = MyMigrations.migrations :+ SqlMigration(1)(List(
  sqlu"""create table "users" ("id" INTEGER NOT NULL PRIMARY KEY,"first" VARCHAR NOT NULL,"last" VARCHAR NOT NULL)"""

Or type-safe Slick queries:

MyMigrations.migrations = MyMigrations.migrations :+ DBIOMigration(2)(
  DBIO.seq(Users ++= Seq(
    UsersRow(1, "Chris","Vogt"),
    UsersRow(2, "Yao","Li")

Or use slick-migration-api:

MyMigrations.migrations = MyMigrations.migrations :+ APIMigration(3)(
    renameColumn(_.first, "firstname").
    renameColumn(_.last, "lastname"))

(Note: APIMigration is not supported in versions prior to v0.2.3)

Don't worry about keeping the Scala code and your database schema consistent. Our source code generator will have it generated for you.

Key Features:

  • Supports for type-safe database migration with Slick and slick-migration-api.
  • A source code generator to generate and manage Scala models from your database schemas.
  • A tool to help you manage your dev db with git, with supports for branching and merging.
  • High customizability.

How to Use

Scala-Forklift supports both Slick 3.1 and Slick 3.2. The latest versions of Scala-Forklift are given below:

Scala Version Slick Version SBT dependency
2.11.x 3.1.x libraryDependencies += "com.liyaos" %% "scala-forklift-slick" % "0.2.3"
2.12.x, 2.11.x 3.2.x libraryDependencies += "com.liyaos" %% "scala-forklift-slick" % "0.3.1"
2.13.x, 2.12.x 3.3.x libraryDependencies += "com.liyaos" %% "scala-forklift-slick" % "0.3.2"

Known Issues

  • The reset command may not correctly handle database schemas with foreign keys.
You can’t perform that action at this time.
