MemoryAdapter

Zero-dependency in-memory store. No database required.

When to use

• Unit and integration tests — no MongoDB needed
• Local prototyping
• Demo / playground environments

Usage

import hiroki, { MemoryAdapter } from 'hiroki';

const adapter = new MemoryAdapter('Products');

hiroki.importModel('Products', { adapter });

In tests

import { MemoryAdapter } from 'hiroki';

const adapter = new MemoryAdapter('Users');
hiroki.importModel('Users', { adapter });

afterEach(() => adapter.clear());  // reset between tests

Supported features

• All filter operators: eq, ne, gt, gte, lt, lte, in, nin, regex
• sort, limit, offset
• select (field projection)
• Legacy conditions object
• count, distinct

IDs

Auto-increments from 1. Created documents get an id field (string).

clear()

Resets all stored documents and the ID counter:

adapter.clear();

Limitations

• No persistence — data lives in process memory
• No populate (relation resolution)
• No schema validation
• distinct uses strict equality, not collation
