# VelocityVibe Racers [VelocityVibe Racers](https://printed-racecars.mock.shop/llms.txt) is a [mock.shop](https://www.mock.shop/) sample store for building against a model-racing and track-components catalog before a real Shopify store is ready. It includes toy race car and track sets, scale model kits, building toys, and decorative patches. The catalog has 24 products across 4 collections. Products have two or three variants, but their gallery image counts don’t necessarily match. The straight race track model has three variants and two gallery images. mock.shop is an auth-free Shopify Storefront GraphQL API backed by sample reference stores. Find out more about [mock.shop sample stores](https://www.shopify.com/blog/mock-shop). ## When to use this store Choose VelocityVibe Racers when you’re building a model-racing and track-components shop with product galleries and scale selectors. Use VelocityVibe Racers for: - Model-racing storefronts with product galleries - Reading the explicit image association on each variant - Handling more variants than gallery images without a missing-image error Choose another mock.shop store if you need nonshipping digital goods or multi-option products. Browse to find a store that matches your catalog. ## Example VelocityVibe Racers query Here’s an example GraphQL `POST` request that retrieves a track model’s gallery and each variant’s image association from : ```bash curl https://printed-racecars.mock.shop/api \ -H 'Content-Type: application/json' \ --data '{"query":"{ track: product(handle: \"3d-printed-straight-race-track-model\") { id title images(first: 3) { pageInfo { hasNextPage } nodes { id url altText } } variants(first: 3) { pageInfo { hasNextPage } nodes { id selectedOptions { name value } image { id url altText } } } } }"}' ``` This query returns the product ID and title, both gallery images, and all three variants with IDs, selected options, and image associations. The `1:24`, `1:32`, and `1:64` Scale variants all reference the first gallery image. Adapt the query for your storefront needs. The endpoint doesn't require authentication or an access token. Read for catalog details and store-specific instructions. ## What this catalog lets you test Build model-racing product pages that combine galleries with scale choices. In a client that changes the gallery selection when a variant changes, use the returned `variant.image` association rather than `images[variantIndex]`. The `1:32` variant doesn’t reference the second gallery image, and the `1:64` variant doesn’t need a nonexistent third image. Use this product to test image selection independently of the variant selector, not to infer scale accuracy or compatibility between track components.

It gives the assistant the store domain and directs it to the catalog instructions before it starts writing code. ```text Build me a Hydrogen storefront using printed-racecars.mock.shop as the store domain. Setup instructions: printed-racecars.mock.shop/llms.txt ``` Shopify also provides a [mock.shop starter project](https://github.com/Shopify/mock-shop-starter): a Hydrogen storefront with product pages, collection browsing, and a working cart already connected to mock.shop. You or your AI coding tool can customize this code instead of building those pieces from scratch. Follow the repository’s setup instructions, then set `PUBLIC_STORE_DOMAIN=printed-racecars.mock.shop` in `.env` and restart the dev server to use VelocityVibe Racers’ catalog. Leave `PUBLIC_STOREFRONT_API_TOKEN` empty; mock.shop doesn’t require a token. ## Move to a real Shopify store mock.shop uses fictional, read-only catalog data. Cart operations work, and checkout is mocked: no payment is taken and no real order is placed. The Customer Account API isn’t supported. When you’re ready to launch, point your storefront at a Shopify store and add that store’s public Storefront API token. If you don’t have a Shopify store yet, [start a Shopify free trial](https://www.shopify.com/free-trial) to create one. Read the [mock.shop developer documentation](https://shopify.dev/docs/storefronts/headless/mock-shop) for setup and migration details. ## Store facts | | | |---|---| | Store handle | `printed-racecars` | | Catalog model | Model-racing products with galleries and product-specific variants | | Products | 24 | | Collections | 4 | | Categories | 9 | | Variants per product | 2–3 | | Compare-at prices | 6 products | | Requires shipping | All products | | API endpoint | | | Store instructions | | | Browser preview | |
