Validate requests and responses

Set validator to { request: 'zod', response: 'zod' } so the client checks both request and response bodies against the generated schemas at runtime, and add @kubb/plugin-zod to the plugins list. The 'zod' shorthand covers responses only, so name both directions to validate requests too.

kubb.config.ts

import { defineConfig } from 'kubb/config'
import { pluginTs } from '@kubb/plugin-ts'
import { pluginZod } from '@kubb/plugin-zod'
import { pluginFetch } from '@kubb/plugin-fetch'

export default defineConfig({
  input: './petStore.yaml',
  output: { path: './src/gen', clean: true },
  plugins: [
    pluginTs(),
    pluginZod(),
    pluginFetch({
      validator: { request: 'zod', response: 'zod' },
    }),
  ],
})
