TQuery extends InMemoryQuery<TDoc> = InMemoryQuery<TDoc>,
>(): InMemoryConnector<TDoc, TQuery, TKey>

Creates an in-memory NoSQL document store for testing and development.

Documents are stored in a Map and will be lost when the process exits. Queries use predicate functions to filter documents.

await users.put("user-1", { name: "Alice", status: "active" }).run();
const user = await users.get("user-1").run();

Query with predicate

const activeUsers = await users
  .find((u) => u.status === "active")
  .map((u) => u.name)
  .collect();
