Use ArkType schemas to generate your Prisma schema
pnpm add truth@npm:single-source-of-truth arktype
```sh
pnpm add truth@npm:single-source-of-truth arktype
```
```ts
// src/shapes.ts
import { field, model, relation } from 'arktype';
export const User = model({
id: field('string').id_(),
name: field('string | null'),
posts: () => relation(() => Post.array()),
});
export type User = typeof User.infer;
// ^? { id: string, name: string | null }
export const Post = model({
id: field('string').id_(),
authorId: field('string'),
title: field('string'),
author: () => relation(() => User).reference('authorId', 'id'),
});
export type Post = typeof Post.infer;
// ^? { id: string, authorId: string, title: string }
```
```ts
// truth.config.ts
import { defineConfig } from 'truth/config';
export default defineConfig(({ registry, arktype, prisma }) => {
await arktype.import(registry, './src/shapes.ts');
await prisma.export(registry, './prisma/generated.prisma');
});
```
```sh
truth
```
```prisma
model User {
id String @id
