Full Stack Scala

on YouTube ↗40m

" summary

Builds a Scala full‑stack using Scala.js on the client and JVM on the server with autowire + boopickle and scalatags, demonstrating a shared API (case class Person) that yields compiler errors when front and back disagree, type‑safe RPC, and shared validation that fails safely on the server. Shows fastOptJS for quick iteration and fullOptJS for deployment (dev bundle ~1.21 MB, optimized ~260 KB), a canvas parser that draws shapes from parsed input, and live server‑sent events sourcing tweets into the client.
