Zod Event

DRY Castore EventType definition using zod.

📥 Installation

# npm
npm install @castore/zod-event

# yarn
yarn add @castore/zod-event

This package has @castore/core and zod (above v3) as peer dependencies, so you will have to install them as well:

# npm
npm install @castore/core zod

# yarn
yarn add @castore/core zod

👩‍💻 Usage

import z from 'zod';

import { ZodEventType } from '@castore/zod-event';

const pokemonAppearedPayloadSchema = z.object({
  name: z.string(),
  level: z.number(),
});

const pokemonAppearedMetadataSchema = z.object({
  trigger: z.enum(['random', 'scripted']).optional(),
});

// 👇 generics are correctly inferred
const pokemonAppearedEventType = new ZodEventType({
  type: 'POKEMON_APPEARED',
  payloadSchema: pokemonAppearedPayloadSchema,
  metadataSchema: pokemonAppearedMetadataSchema,
});

👇 Equivalent to:

import { EventType } from '@castore/core';

const pokemonAppearedEventType = new EventType<
  'POKEMON_APPEARED',
  { name: string; level: number },
  { trigger?: 'random' | 'scripted' }
>({ type: 'POKEMON_APPEARED' });
