Using Scala.js and functional reactive programming for developing (enterprise) applications

on YouTube ↗44m

" summary

SAP builds a Scala-based cloud app stack that compiles server Scala and front-end Scala.js code, generates UI bindings against SAP UI5, and pulls labels and types from a metadata store covering 120,000 tables so fields and SQL macros compile with real schemas. The team open-sources a functional-reactive library called Dive that implements signals and events, lazy evaluation and garbage collection, and enforces an atomicity guarantee for simultaneous updates — demonstrated by a working voting UI and reusable UI dataflow patterns.
