Typesafe Activator is a single download to get you started building Reactive applications. To get started, you’ll need a JDK, your favorite editor or IDE, and Activator. Activator includes the sbt build tool, a quick-start GUI, and a catalog of template applications.
Jump start development with tutorials and code samples in Activator
Activator’s quick-start UI walks you through Typesafe Reactive Platform tutorials and is a hub for developers wanting to build Reactive applications. Activator updates in real-time with new content from Typesafe and select third parties. Through tutorials and sample code, it helps you learn more about and adopt the range of offerings, both commercial and open source, found in the Typesafe ecosystem.
Common development patterns are presented through reusable templates that are linked to in-context tutorials explaining step-by-step exactly how things work. For tutorial purposes, the Activator UI has a simple editor and the ability to compile, test, and run template applications. As you move into real-world applications, Activator can export to leading IDEs where you might continue working.
Activator is powered by the sbt build engine
sbt is an interactive build tool with customizable build tasks and an "execute-task-on-file-change" feature, allowing you to focus on writing your code. Typesafe Activator includes sbt’s default command line mode, then adds a quick-start UI (the
activator ui command) and a template catalog (accessible in the UI or via the
activator new command). Type activator shell to access sbt’s traditional command line prompt, or you can run Activator with a specific task name (for example,
activator compile) just as you would with plain sbt.
Use sbt (via Activator) to compile Java and Scala code, run tests, package JARs and Docker images, and even execute code directly in the Scala interpreter. Builds are written in a Scala-based syntax, with a mix of declarative and imperative features. sbt is inherently parallel, and automatically executes your build tasks across multiple cores. sbt also manages dependencies found in existing Maven or Ivy package repositories.
Typesafe Activator gets you started with Play and the Typesafe Reactive Platform. It is a hub for developers that want to build Reactive applications, providing both a command line and a GUI for creating new applications. Getting started is a snap. Just refer to the instructions on the Get Started page.Get Started With Activator
sbt is the engine powering Typesafe Activator. If you have Activator, you already have sbt - but you can download plain sbt (with no UI or template catalog) from scala-sbt.org. A common approach to command line development would be to typeGet Started with sbt
sbt ~testin your project directory, then start coding! Test failures will show up in sbt's console automatically as your code is saved.
