SvelteKit 3 Just Shipped. Here Is Your Migration Checklist.

·5 views

Yesterday the Svelte team shipped SvelteKit 3.0, and by this morning the announcement was sitting on the Hacker News front page with over 350 points and more than 150 comments. That is a strong signal. When a framework whose previous major version came out in 2022 jumps a whole number, thousands of production apps have a migration in their future, and the comment section fills up with people comparing notes on what broke. I write TypeScript and Svelte as part of my daily toolkit, so this release matters to me directly. Full disclosure though: I have not yet run this migration on a production a

Keeping large chart previews and CSV exports consistent

A user loads a year of minute candles, zooms out to see the whole period, then downloads a CSV.
