Svelte5 Best Practices

This is a solid reference for anyone working with Svelte 5's new reactivity system. It covers the shift from stores to runes, slots to snippets, and event dispatchers to callback props. The quick reference table is genuinely useful for looking up when to use $state versus $derived, and the common mistakes section will save you debugging time, especially the SSR state isolation gotcha. If you're migrating from Svelte 4 or just trying to write idiomatic Svelte 5 code, the patterns here are specific enough to copy and adapt. The SvelteKit integration guidance is a nice bonus for full-stack work.
