GraphQL Demo

A hands-on tour of the GraphQL service: an HTTP query, an HTTP mutation, and a WebSocket subscription that connects directly to graphql-service (not proxied through the gateway).

1. Query — products with related products

Fetches the first 5 products and their same-category relatedProducts, demonstrating a genuinely recursive GraphQL resolver.

Query sent over the wire

query Products($limit: Int) {
  products(limit: $limit) {
    data {
      id
      name
      priceCents
      category
      relatedProducts {
        id
        name
      }
    }
    meta {
      total
    }
  }
}

2. Mutation — cancel an order

Fetches your own orders via the orders query, then invokes the cancelOrder mutation on the one you pick.

3. Subscription — live order status

This is backed by real RabbitMQ events, not a mock — trigger a payment or cancellation on this order from another tab/terminal to see a live update appear here.
