Svelte

Le framework à base de compilateur pour des interfaces rapides et légères.

Svelte is a compiler that turns small, readable components into fast JavaScript, and SvelteKit is the framework that turns those components into a complete website. This track teaches Svelte 5 the modern way, with runes, snippets and event attributes such as onclick, then moves on to SvelteKit 2 routing, load functions and form actions, and finishes with production skills: motion, accessibility, server-side rendering and deployment.

You already know JavaScript, so every lesson goes straight to what Svelte adds, with real examples from a small social app called Nova: a like button, a post card, a leaderboard and a profile page.
