Fastify Adapter

The @zenstackhq/server/fastify module provides a quick way to install a full set of CRUD API onto Fastify apps. Combined with ZenStack's powerful access policies, you can achieve a secure data backend without manually coding it.

Installation

npm

npm install @zenstackhq/server@next

pnpm

pnpm add @zenstackhq/server@next

bun

bun add @zenstackhq/server@next

yarn

yarn add @zenstackhq/server@next

Mounting the API

You can integrate ZenStack into your project with the ZenStackFastifyPlugin fastify plugin:

import fastify from 'fastify'
import { ZenStackFastifyPlugin } from '@zenstackhq/server/fastify';
import { RPCApiHandler } from '@zenstackhq/server/api';
import { getSessionUser } from '~/auth';
import { client } from '~/db';
import { schema } from '~/zenstack/schema';

const server = fastify();

server.register(ZenStackFastifyPlugin, {
    apiHandler: new RPCApiHandler({ schema }),
    prefix: '/api/model',
    // getSessionUser extracts the current session user from the request, its
    // implementation depends on your auth solution
    getClient: (request) => client.$setAuth(getSessionUser(request)),
});

The Fastify adapter takes the following options to initialize:

• prefix

  string

  Prefix for the mounted API endpoints. E.g.: /api/model.

• getClient (required)

  (request: FastifyRequest, reply: FastifyReply) => ClientContract<Schema> | Promise<ClientContract<Schema>>

  A callback for getting a ZenStackClient instance for talking to the database. Usually you'll return a client instance with access policy enabled and user identity bound.

• apiHandler (required)

  ApiHandler

  The API handler instance that determines the API specification.
