Introduction

Prisma IDB

You already write Prisma on the server. Now write it in the browser.

Prisma IDB is a Prisma generator that creates a type-safe IndexedDB client with the familiar Prisma Client API. Define your data model once in your Prisma schema, and get a local-first client that works offline — with an optional sync engine that handles conflict resolution and authorization.

const todos = await idb.todo.findMany({
  where: { userId, done: false },
});

Core Features

• Prisma-compatible API — create, findMany, findUnique, update, delete, upsert, and more
• Full type safety — generated from your schema with complete autocomplete
• Local-first — all data in IndexedDB, works offline by default

Sync Engine

When you're ready for server sync, one flag enables:

• Outbox pattern — reliable push with retry and batching
• Ownership DAG — structural authorization tracing records to their owner
• Conflict resolution — server-authoritative changelog materialization
