Elm - Frontend with Guarantees

on YouTube ↗26m

" summary

Claim: Elm runs in production at a web shop that serves clients like Harvard and the European Commission after three and a half years on Angular and a detour through React. The stack uses the Elm architecture with a single unified model, typed messages and pure update functions, yielding no runtime exceptions and easier unit testing. Built apps include an office checkin system, GitHub login, maps, routing, forms and file drag‑and‑drop, and the approach proves pragmatic and stable.
