5 Years of Svelte at Itslearning
summary
Itslearning moves its entire frontend from 2016 onward and repeatedly rewrote the same page across three Svelte versions (2016→2021) to compare real outcomes: the course list page with filtering, sorting, selection and event handlers is rebuilt each time, using Svelte components, prop spreading, lifecycle hooks and a global site store for shared state. The app serves millions worldwide with peaks around ~100k concurrent users, and the rewrites target smaller bundles and faster initial load to keep the UI usable on slow mobile connections.
