Next.js 15 & Svelte 5: Major Upgrades Hit the Web Dev World

Front-End Fire

Jack is away this week speaking at the React Advanced conference in London, so be sure to check out his recorded talk (and all the others) about if React is really dying.

For the news this week, we’ve got a bunch of interesting topics, the first of which is the latest release of Next.js: Next 15. It’s stable and production ready offering React 19 and React Compiler (experimental) support, Turbopack Dev, improvements to caching, and a change to async Request APIs that will allow for simplified rendering and caching in the future.

Svelte 5 is also officially stable and production ready debuting the new Runes system which offers Svelte users fine-grained reactivity control via Signals. Svelte previously relied on the compiler for reactivity, which could begin to break down for larger apps, so it was rewritten from the ground up and Runes was born.
