linforge-adapter-prisma

Prisma adapter for Linforge — production-ready Store implementations backed by Prisma ORM.

Install

npm install linforge-adapter-prisma
# peer dependencies
npm install linforge @prisma/client

Setup

1. Add Prisma models

Copy the models from prisma/schema.prisma into your project's Prisma schema, then run:

npx prisma db push   # or prisma migrate dev

2. Use with linforgeMiddleware

import { linforgeMiddleware } from 'linforge/server';
import { createPrismaStores } from 'linforge-adapter-prisma';
import { PrismaClient } from '@prisma/client';

const prisma = new PrismaClient();

app.use(linforgeMiddleware({
  stateSchema: MyState,
  nodes: [planner, tools],
  stores: createPrismaStores(prisma),
}));

3. Selective stores (optional)

// Only use GraphStore + RunStore, skip step recording and prompt management
const stores = createPrismaStores(prisma, {
  stepPersister: false,
  promptStore: false,
});
