Build and Deploy a GraphQL API to the Edge with Fauna

We're now ready to finish the last piece of the GraphQL API by adding a new query that fetches all products from the Fauna Database.

Inside grafbase/grafbase.config.ts add the following query definition:

g.query('products', {
  resolver: 'products/all',
  returns: g.ref(product).optional().list().optional()
})

Now create the file grafbase/resolvers/products/all.ts and add the following:

import { Client, fql, FaunaError } from 'fauna'

const client = new Client()

export default async function ProductsAll() {
  try {
    const documentQuery = fql`
      products.all() {
        id,
        name,
        price
      }
    `

    const { data } = await client.query(documentQuery)

    return data?.data || []
  } catch (error) {
    if (error instanceof FaunaError) {
      console.log(error)
    }

    return []
  }
}

💡

There's more we can do here to optimize the request to fetch all products and make sure of cursor-based pagination, but we'll do that in the next step.

Now open Pathfinder at http://127.0.0.1:4000 and execute the following GraphQL query:

query {
  products {
    id
    name
    price
  }
}

You should see a response that contains your products and looks something like this:

{
  "data": {
    "products": [
      {
        "id": "372390606454915278",
        "name": "Shoes",
        "price": 1000
      },
      {
        "id": "372397709974307023",
        "name": "Cap",
        "price": 2000
      }
    ]
  }
}
