Offline fallback

shamock does not replace failed requests by itself. Select mock data explicitly in your application.

import { parseMockList } from 'shamock'
import { z } from 'zod'

const product = {
  schema: z.object({ id: z.number(), name: z.string() }),
}
const fixtures = [{ id: 1, name: 'Offline sample' }]

async function loadProducts(useMockData: boolean) {
  if (useMockData) return parseMockList(product, fixtures)

  const response = await fetch('https://api.example.com/products')
  if (!response.ok) throw new Error(`HTTP ${response.status}`)
  return response.json()
}

const products = await loadProducts(true)

Your application can pick the fixture mode for known network failures, while keeping authentication, authorization and validation errors.

To keep the same code path as production, install the Mock API instead: your fetch calls stay unchanged and are answered from seed data.
