Memory adapter

@quickben/db-memory keeps data in process memory. Use it in tests, demos and docs. Data is lost when the process exits.


pnpm add @quickben/db-memory


import { defineConfig } from "@quickben/core";
import { memoryAdapter } from "@quickben/db-memory";
 
import { posts, tags, users } from "./collections";
 
export default defineConfig({
  db: memoryAdapter({
    initialData: {
      tags: [
        {
          id: "t1",
          name: "news",
          createdAt: "2026-01-01T00:00:00.000Z",
          updatedAt: "2026-01-01T00:00:00.000Z",
        },
      ],
    },
  }),
  collections: [users, tags, posts],
});

Options

Option	Purpose
`initialData`	Documents to load before the first call, keyed by slug. Stored as given.

Behavior

Topic	Behavior
Transactions	Copy-on-write. Changes apply to the latest data on commit. Unique values are checked again on commit.
Isolation	Reads outside a transaction do not see its writes until commit.
`raw`	`{ collections }`: the documents the adapter can see, keyed by slug and id.
Contract	Reference adapter for the shared contract tests.

Tests

Use createQuickben to get a fresh instance per test:


import { createQuickben } from "@quickben/core";
 
const fresh = await createQuickben(config);
await fresh.create("tags", { name: "test" }, { user });

The config holds one adapter. For isolated tests, build the config in a function that calls memoryAdapter() each time.
