@agentic-fullstack/postgres

PostgreSQL adapter and LangGraph checkpointer for agentic-fullstack. Implements the DBAdapter interface from @agentic-fullstack/core and provides the persistence layer used by both the engine and the server.

Installation

npm install @agentic-fullstack/postgres

Usage

import {
  createPostgresAdapter,
  createPostgresCheckpointer,
} from "@agentic-fullstack/postgres";

const adapter = await createPostgresAdapter({ pool });
const checkpointer = await createPostgresCheckpointer({ pool });

Both functions accept a pg Pool instance. createPostgresAdapter runs schema setup on first call — it is idempotent and safe to call on every startup. Table names default to agentic_events, agentic_messages, and agentic_chunks, and can be overridden via the config.

Pass both to createEngine from @agentic-fullstack/engine, and adapter alone to createServer from @agentic-fullstack/server.

See src/index.ts for the full configuration reference.
