Twill CMS GraphQL 🔭

Twill GraphQL provides easy access to query-specific fields from Twill CMS modules and user-defined modules with GraphQL.

The project is heavily inspired by twill-api

Documentation

Check the documentation.

Technologies

This package uses nuwave/lighthouse and mll-lab/laravel-graphql-playground for providing easy access to models and playground UI for exploring server schemas and testing.

Big props to them and Twill developers for creating such amazing projects.

Per default graphql endpoint serves on /graphql and playground is available on /graphql-playground

Install package

From composer

composer require kallefrombosnia/twill-graphql

Configuration

Deploy default graphql schema

$ php artisan twill:graphql:deploy

Deploy lighthouse config

$ php artisan vendor:publish --tag=lighthouse-config

This is not hardcoded into our config since lighthouse is constantly changing their codebase

After deploying lighthouse config, find it in the ./config/lighthouse.php

Find namespaces which should look like this.

'namespaces' => [
    'models' => ['App', 'App\\Models'],
    'queries' => 'App\\GraphQL\\Queries',
    'mutations' => 'App\\GraphQL\\Mutations',
    'subscriptions' => 'App\\GraphQL\\Subscriptions',
    'interfaces' => 'App\\GraphQL\\Interfaces',
    'unions' => 'App\\GraphQL\\Unions',
    'scalars' => 'App\\GraphQL\\Scalars',
    'directives' => ['App\\GraphQL\\Directives'],
    'validators' => ['App\\GraphQL\\Validators'],
],

At the moment only config option needed for us is models Change it like this to load default Twill modules into it (make sure you have Twill CMS installed).

    'namespaces' => [
        'models' => ['A17\\Twill\\Models', 'App', 'App\\Models'],
        ...
    ],

This will autoload all package models first so make sure your Laravel models and Twill custom models are not named the same as Twill CMS modules.

Reserved: Feature, Block, File, Media, Setting, Tag, User.

And you are ready to go.

Project roadmap

  • Create wrapper around Twill default models for relations
  • Add examples
  • Write tests
  • Create composer package (publish)
  • Create guards example
  • Create mutations
  • More tests
  • Subscriptions
  • Tests for subscribtions
  • TBA

Query on Twill custom user models

For example, we have the Category model which is located in app\Models By lighthouse configuration this model is also loaded.

// app/Models/Category.php
<?php

namespace App\Models;

use A17\Twill\Models\Model;

class Category extends Model 
{
  
    protected $fillable = [
        'published',
        'title',
        'description',
    ];
    
}

Edit graphql/schema.graphql

scalar DateTime @scalar(class: "Nuwave\\Lighthouse\\Schema\\Types\\Scalars\\DateTime")  

type Query {

  "Query on Category module"
  categories: [Category!]! @all @softDeletes
  category(id: Int! @eq): Category @find

} 

type Category {
  id: ID!
  published: Int!
  title: String
  description: String
  created_at: DateTime
  updated_at: DateTime
}

Let's load Graphql playground and test it.

All categories

{
    categories {
        id
        published
        title
        description
        created_at
        updated_at
    }
}

Result

{
    "data": {
        "categories": [
        {
            "id": "1",
            "published": 1,
            "title": "Books",
            "description": "Just a plain description of the books category",
            "created_at": "2022-02-06 18:49:16",
            "updated_at": "2022-02-06 18:58:10"
        },
        {
            "id": "2",
            "published": 1,
            "title": "Cars",
            "description": "Cars are awesome.",
            "created_at": "2022-02-08 01:54:21",
            "updated_at": "2022-02-08 01:54:35"
        }
        ]
    }
}

Query specific category by id

{
    category(id: 2) {
        id
        published
        title
        description
        created_at
        updated_at
    }
}

Result

{
    "data": {
        "category": {
            "id": "2",
            "published": 1,
            "title": "Cars",
            "description": "Cars are awesome.",
            "created_at": "2022-02-08 01:54:21",
            "updated_at": "2022-02-08 01:54:35"
        }
    }
}
