Schema

Supported Libraries

Ventyd uses Standard Schema, so you can use any compatible validation library.

Which One Should I Choose?

• Valibot: Smallest bundle size, modern and modular
• Zod: Most popular, largest ecosystem
• TypeBox: JSON Schema support, great for APIs
• ArkType: Fastest validation, elegant syntax

Pick any - they all work great with Ventyd!

Custom Event Seperator

By default, events are named entity:event (e.g., user:created). You can customize this:

const schema = defineSchema("user", {
  schema: valibot({
    event: { created: v.object({ ... }) },
    state: v.object({ ... }),
    namespaceSeparator: "/" // Use "/" instead of ":"
  }),
  initialEventName: "user/created" // Match the separator
});
