@tanstack/db

Integrating TanStack DB with meta-frameworks (TanStack Start, Next.js, Remix, Nuxt, SvelteKit). Client-side only: SSR is NOT supported — routes must disable SSR. Preloading collections in route loaders with collection.preload(). Pattern: ssr: false + await collection.preload() in loader. Multiple collection preloading with Promise.all. Framework-specific loader APIs.
