function createLiveQueryCollection<TContext, TResult>(query): Collection<TResult, string | number, {}>

Definiert in: packages/db/src/query/live-query-collection.ts:424

Erstellt eine Live-Query-Collection direkt

• TResult extends object = { [K in string | number | symbol]: (TContext["result"] extends object ? any[any] : TContext["hasJoins"] extends true ? TContext["schema"] : TContext["schema"][TContext["fromSourceName"]])[K] }

Parameter

query

(q) => QueryBuilder<TContext>

Gibt zurück

Collection<TResult, string | number, {}>

Beispiel

typescript

// Minimal usage - just pass a query function
const activeUsers = createLiveQueryCollection(
  (q) => q
    .from({ user: usersCollection })
    .where(({ user }) => eq(user.active, true))
    .select(({ user }) => ({ id: user.id, name: user.name }))
)

// Full configuration with custom options
const searchResults = createLiveQueryCollection({
  id: "search-results", // Custom ID (auto-generated if omitted)
  query: (q) => q
    .from({ post: postsCollection })
    .where(({ post }) => like(post.title, `%${searchTerm}%`))
    .select(({ post }) => ({
      id: post.id,
      title: post.title,
      excerpt: post.excerpt,
    })),
  getKey: (item) => item.id, // Custom key function (uses stream key if omitted)
