Building frontend applications with Scala.js and scalajs-react

Oct 11, 2017 · Hamburg, Germany

In July 2017 Scala.js reached the 1.0.0-M1 milestone. The talk will try to answer the question if it is safe to use scala.js and scalajs-react for building production frontend applications.


• Disadvantages of JS-usage (language flaws, absence of typing, runtime errors)

• Alternatives (TypeScript, Flow, ClosureScript, Elm, Scala.js) and brief comparison (subjective)

• Scala.js top features ("native" scala feeling, sbt, interoperability with js, moderate js-bundle size)

• Difficulties to use pure Scala.js to build frontend application (necessity to build own router, UI state management system, configure assets bundler)

• Scalajs-react features (Functional programming features, interoperability with pure js react components, integration with scalaz, routing, testing packages)

• Related packages (diode - redux-like state management system, scalajs-react-bridge - boilerplate less way to use pure js react components)

Expected duration: 45 min - 1 hour

The Speaker:

Andrii Malaman ( is a full-stack engineer with hands-on experience in JavaScript, Python, Scala. Andrii has implemented multiple SPA frontend applications with different JS-frameworks (React.js, Angular, Angular.js, Backbone) and has experience with Scala.js and scalajs-react as well.


The talk will be in English.

Beverages (water, soft drinks, beer) will be provided (but not food).

As usual, we'll have some casual get-together after the talk, either on the terrace or in one of the many pubs in the Schanzenviertel.

Accessibility: The meeting area is accessible by wheelchair (use the elevator to get to the 1st floor).
