@ilmek/checkpoint-sqlite

A durable ilmek checkpointer in a single SQLite file — zero dependencies, on Node's built-in node:sqlite. A parked interrupt survives a process restart, a deploy, or a crash.

npm install @ilmek/core @ilmek/checkpoint-sqlite

import { SqliteCheckpointer } from "@ilmek/checkpoint-sqlite";

const cp = await SqliteCheckpointer.open("./agent.db");   // creates + migrates
await run(graph, input, { threadId, checkpointer: cp });

Talks to a duck-typed database (exec/prepare), so better-sqlite3 drops in unchanged. Requires Node ≥ 22.5. For threads shared across processes, use @ilmek/checkpoint-postgres.
