Kizuna.model

Give a Zod schema a name, so OpenAPI and the Swift and Kotlin generators emit a named type for it.

pnpm add kizunajs@beta

bun add kizunajs@beta

npm install kizunajs@beta

import { Kizuna } from 'kizunajs';

Parameters

Kizuna.model(options: ModelOptions): ZodType

Returns

The Zod schema with metadata attached, usable anywhere a Zod schema is.

Example

import { Kizuna } from 'kizunajs';
import { z } from 'zod';

export const UserSchema = Kizuna.model({
    title: 'User',
    description: 'A user in the system',
    schema: z.object({
        id: z.string(),
        name: z.string(),
        email: z.email(),
    }),
});

Effect on generators

With Kizuna.model:

• OpenAPI: the schema is extracted into components.schemas.User and every usage becomes a $ref reference
• Swift: an object becomes public struct User, a z.enum becomes public enum EventKind, shared across all routes that reference it
• Kotlin: an object becomes @Serializable data class User, a z.enum becomes enum class EventKind, shared across all routes that reference it

Extracting TypeScript types

Export a type alongside the schema with z.infer:

export type User = z.infer<typeof UserSchema>;
