I do not know how to ask but I summarize what I want to do. I have a laravel server with lighthouse I do not handle databases or models, my data source is an api that returns the data in a json, now my query is how do I convert or map the json for a graphql query?

the structure of my json is more or less like this:

{
    "order" : 
    [
        {
            "details":
            {
              "id": "file",  
              "value": "File"
            }
        },
        {
            "menu":
            {
              "menuitem":
              [
                {"value": "New", "onclick": "CreateDoc()"},  
                {"value": "Open", "onclick": "OpenDoc()"},  
                {"value": "Save", "onclick": "SaveDoc()"}
              ]
            }
        }
    ]
}

and the structure of my schematic is something like this:

type order {
  details: details
  menu: menu

}

type details {
  id: String
  value: String
}

type menu {
  menuitem: menuitem
}

type menuitem {
  value: String
  onclick: String
}

type query {
  orders: [order]
}

the solution is for the custom resolver or the eloquent models or something else, if someone could guide me it would be very helpful

You can just return an array with the shape of your GraphQL types. I mean, if your custom resolver return something like this, it will work:

<?php

class CustomResolver {
    public function __invoke($root, array $args) 
    {
        return [
            'menu' => [
                'menuitems' => [
                    ['value' => 'New', 'onclick' => 'CreateDoc()'],
                ],
            ],
        ];
    }
}

But you also have to modify your menu type to include an array of menuitems:

type menu {
  menuitem: [menuitem!]
}

So, basically, just transform the response of your api to the shape that GraphQL types expects.

  • Thank you very much, your guide helped me a lot but I still have not solved the problem that is converting the json to an array, something like how this page does it: [json-php-array-converter](https://appdevtools.com/json-php-array-converter) – Steve Silva Jan 09 '22 at 06:10
  • Try with `json_decode($json, true)` https://www.php.net/manual/es/function.json-decode.php – Enzo Notario Jan 09 '22 at 13:59
