Modeling with zod

Create a model

import { z } from 'zod'

export const Customer = z.object({
  firstName: z.string(),
  lastName: z.string(),
  age: z.number(),
  address: z.object({
    streetAddress: z.string(),
    city: z.string(),
    state: z.string(),
    postalCode: z.string(),
  }),
  contact: z.array(
    z.object({
      type: z.string(),
      value: z.string(),
    }),
  ),
})

// type and value have the same name
export type Customer = z.infer<typeof Customer>

Inferred type

Typescript can fully infer the type from the value:

Usage

// either throws an error, or it's a valid Customer
const customer = Customer.parse(request.body)
