Getting Started with Scala.js, Laminar and Vite

Please log in to watch this conference skillscast.

Starting from scratch, we build a small Scala.js application with a minimal, live-editable bar chart. We show a setup for a fast save-refresh cycle. We use the following technologies:

• VS Code with Metals as IDE
• sbt, with the sbt-scalajs plugin
• Vite, a fast JavaScript packager and development server
• Laminar, a Scala.js UI library based on FRP (Functional Reactive Programming)
• Chart.js, a JavaScript library to display nice graphs
• ScalablyTyped, to get static types for Chart.js

A significant portion of the talk focuses on Laminar and its FRP model. We do not talk about the server-side aspects.
