Udash is a Scala.js framework for building beautiful and maintainable web applications.

Combined forces of Scala & JavaScript

Type safe (HTML, CSS & JS)

In cooperation with ScalaTags and ScalaCSS libraries, Udash provides a type safe layer over HTML, CSS and JS with powerful data binding into DOM templates.

Compiled to JS

Scala is compiled to highly efficient JavaScript with no need to maintain Javascript code. It is also easy to use it with good, old JavaScript libraries like Twitter Bootstrap or jQuery.

Shared Scala code

Udash brings out of the box the RPC system with a shared data model and interfaces between frontend and backend, which boosts development and keeps the codebase consistent.

Why Udash?

Reactive Data Bindings

Automatically synchronise user interface with your data model.

Type-safe RPC & REST

A client↔server communication based on typed interfaces. Bidirectional RPC via WebSockets out of the box.

User Interface Components

Twitter Bootstrap components enriched with Udash features.


Udash provides a frontend routing mechanism based on URL path or fragment, states and views.


Translations served by the backend or compiled into JavaScript.

Project generator

Generate a customized application from a Giter8 template, compile and try it out in 5 minutes.


Udash provides a complete support for your web application and the communication with the server but does not influence your backend implementation.


The whole framework code is available on GitHub under Apache v2 license.

IDE support

With any IDE supporting the Scala language. No extra plugin needed.
