ZenStack is a Node.js/TypeScript toolkit that simplifies the development of a web app's backend. It enhances Prisma ORM with a flexible Authorization layer and auto-generated, type-safe APIs/hooks, unlocking its full potential for full-stack development.
Our goal is to let you save time writing boilerplate code and focus on building real features!

ZenStack incrementally extends Prisma's power with the following four layers:
ZenStack introduces a data modeling language called "ZModel" - a superset of Prisma schema language. It extended Prisma schema with custom attributes and functions and, based on that, implemented a flexible access control layer around Prisma.
// base.zmodel
abstract model Base {
id String @id
author User @relation(fields: [authorId], references: [id])
authorId String
// 🔐 allow full CRUD by author
@@allow('all', author == auth())
}
// schema.zmodel
import "base"
model Post extends Base {
title String
published Boolean @default(false)
// 🔐 allow logged-in users to read published posts
@@allow('read', auth() != null && published)
}
The zenstack
CLI transpiles the ZModel into a standard Prisma schema, which you can use with the regular Prisma workflows.
At runtime, transparent proxies are created around Prisma clients for intercepting queries and mutations to enforce access policies.
import { enhance } from '@zenstackhq/runtime';
// a regular Prisma client
const prisma = new PrismaClient();
async function getPosts(userId: string) {
// create an enhanced Prisma client that has access control enabled
const enhanced = enhance(prisma, { user: userId });
// only posts that're visible to the user will be returned
return enhanced.post.findMany();
}
Server adapter packages help you wrap an access-control-enabled Prisma client into backend CRUD APIs that can be safely called from the frontend. Here's an example for Next.js:
// pages/api/model/[...path].ts
import { requestHandler } from '@zenstackhq/next';
import { enhance } from '@zenstackhq/runtime';
import { getSessionUser } from '@lib/auth';
import { prisma } from '@lib/db';
// Mount Prisma-style APIs: "/api/model/post/findMany", "/api/model/post/create", etc.
// Can be configured to provide standard RESTful APIs (using JSON:API) instead.
export default requestHandler({
getPrisma: (req, res) => enhance(prisma, { user: getSessionUser(req, res) }),
});
Plugins can generate strong-typed client libraries that talk to the aforementioned APIs. Here's an example for React:
// components/MyPosts.tsx
import { useFindManyPost } from '@lib/hooks';
const MyPosts = () => {
// list all posts that're visible to the current user, together with their authors
const { data: posts } = useFindManyPost({
include: { author: true },
orderBy: { createdAt: 'desc' },
});
return (
<ul>
{posts?.map((post) => (
<li key={post.id}>
{post.title} by {post.author.name}
</li>
))}
</ul>
);
};
The following diagram gives a high-level architecture overview of ZenStack.
- Access control and data validation rules right inside your Prisma schema
- Auto-generated OpenAPI (RESTful) specifications, services, and client libraries
- End-to-end type safety
- Extensible: custom attributes, functions, and a plugin system
- A framework-agnostic core with framework-specific adapters
- Uncompromised performance
- Prisma schema generator
- Zod schema generator
- SWR and TanStack Query hooks generator
- OpenAPI specification generator
- tRPC router generator
- 🙋🏻 Request for a plugin
- Custom attributes and functions
- Multi-file schema and model inheritance
- Polymorphic Relations
- Strongly typed JSON field
- 🙋🏻 Request for an extension
The sample repo includes the following patterns:
