Play with GraphQL

Go to (http://localhost:3009/graphiql) and paste following query to run

// page 1, limit 1 item
{
  product{
    productFind(options: {
      offset:0, limit: 1
    }) {
      edges {
        node {
          name
          price
          brand{
            name
          }
        }
      }
    }
  }
}

// Get all products which name like 'iPhone'
{
  product{
    productFind(filter:{
      where: {
        name: {
          like: "iPhone"
        }
      }
    }) {
      edges {

            name
          }
        }
      }
    }
  }
}

// filter in sub query
{ 
  brand {
    brandFind{
      edges {
        node {
          products (filter: {
            where: {
              name: {
                ilike: "%plus%"
              }
            }
          }) {
            edges {
              node {
                id
                name
              }
