loader

Use a route loader to prefetch critical data from an external cache or data library before the route renders. The component then reads the same cache, while router dehydration and hydration can transfer that data between server and client.

Syntax

createFileRoute('/path')({ loader: () => dataClient.query(options), component: Component })
