MemoryAdapter

MemoryAdapter stores everything in a Map. Data is lost when the process exits.

How it works

• Each collection is a Map<ID, Record>
• IDs are auto-incrementing numbers (1, 2, 3, ...)
• On schema connect, collections are pre-created
• Transactions take a snapshot and restore on error

When to use

• Unit and integration tests
• Server-side rendering
• CLI tools and scripts
• Demos and prototyping
• Node.js environments

Explicit instantiation

import { MemoryAdapter, Database } from "ctrodb"

const db = new Database({
  adapter: new MemoryAdapter(),
})

ID format

Auto-generated IDs are numbers. You can also provide string IDs:

await todos.create({ id: "my-custom-id", title: "Custom" })

Transaction behavior

On transaction start, MemoryAdapter snapshots all maps. If the transaction callback throws, the snapshot is restored. Nested transactions are not supported.
