Beyond Hello World and Todo Lists
summary
Two customer apps are described: “Ferrari,” an internal drag‑and‑drop news layout tool started on Elm 0.15 and upgraded to 0.16/0.17 with single‑sign‑on, and “D25,” a simple social feed built with Elm 0.16→0.17 using Sebastian Porto’s hop for routing. Practical claims: avoid premature abstraction, refactor after ~20 modules, prefer functions over stateful components, use context pattern to pass global values, use remote data pattern for loading states, alias large numeric IDs as floats, rely on elm‑format, ports and E2E tests where needed.
