Full relational support for querying connected data
Typescript support for all data returned from queries

use-messages.ts
import { useQuery } from "@triplit/react"
import { client } from "@/lib/triplit"

export function useMessages(convoId: string) {
  const deliveredMessagesQuery = client
    .query("messages")
    .where("conversationId", "=", convoId)
    .order("created_at", "DESC")
    .syncStatus("confirmed")

  const {
    results: messages,
    fetchingRemote,
    fetching,
    error,
  } = useQuery(client, deliveredMessagesQuery)
}
