STEP-7 GraphQL types, Helpers
As we have successfully established a connection with backend and frontend, let's prepare and collect all configurations we created at STEP-3 transfer.
- 1.First of all, we going to modify our schema.graphqls to gain an understanding of our data structure
ScandiPWA/SocialShareGraphQl/etc/schema.graphqls
type Query {
socialShare: socialShareType @resolver(class:"\\ScandiPWA\\SocialShareGraphQl\\Model\\Resolver\\SocialShare")
}
type socialShareType {
socialShareConfig: socialShareConfig
providers: [ socialShareProvider ]
}
type socialShareConfig {
enabled: Boolean
rounded: Boolean
size: String
categoryPage: Boolean
productPage: Boolean
homePage: Boolean
}
type socialShareProvider {
id: String
counter: Boolean
additional: String
}
Ok now we know how our data structure will look like, then we going to pass data through graphql, will create a Helper which will provide socialShareConfig and providers and map all fields.
2. Create Helper folder in <MODULE ROOT> and DataProvider.php in it
ScandiPWA/SocialShareGraphQl/Helper/DataProvider.php
<?php
declare(strict_types=1);
namespace ScandiPWA\SocialShareGraphQl\Helper;
use Magento\Framework\App\Config\ScopeConfigInterface;
/**
* @package ScandiPWA\SocialShareGraphQl\Helper
*/
class DataProvider
{
const SOCIALSHARE_CONFIG = 'socialshare/general/';
const SOCIALSHARE = 'socialshare/';
const ENABLE = 'enable';
const ROUNDED = 'rounded';
const SIZE = 'size';
const HOME_PAGE = 'home_page';
const CATEGORY_PAGE = 'category_page';
const PRODUCT_PAGE = 'product_page';
const COUNTER = 'enable_counter';
const SUFFIX = 'suffix';
const APP_ID = 'app_id';
const FB_MSG = 'facebook_messenger';
const EMAIL = 'email';
const PROVIDERS = [
'facebook',
'facebook_messenger',
'telegram',
'whatsapp',
'linkedin',
'email',
];
/**
* @var ScopeConfigInterface
*/
protected $scopeConfig;
/**
* DataProvider constructor.
* @param ScopeConfigInterface $scopeConfig
*/
public function __construct(
ScopeConfigInterface $scopeConfig
) {
$this->scopeConfig = $scopeConfig;
}
/**
* @return array
*/
public function getSocialShareConfig() {
return [
'enabled' => $this->getConfig(self::SOCIALSHARE_CONFIG. self::ENABLE),
'rounded' => $this->getConfig(self::SOCIALSHARE_CONFIG. self::ROUNDED),
'size' => $this->getConfig(self::SOCIALSHARE_CONFIG. self::SIZE),
'categoryPage' => $this->getConfig(self::SOCIALSHARE_CONFIG. self::CATEGORY_PAGE),
'productPage' => $this->getConfig(self::SOCIALSHARE_CONFIG. self::PRODUCT_PAGE),
'homePage' => $this->getConfig(self::SOCIALSHARE_CONFIG. self::HOME_PAGE)
];
}
/**
* @return array
*/
public function getSocialShareProviders() {
$result = [];
foreach (self::PROVIDERS as $provider) {
$data = [];
switch ($provider) {
case self::FB_MSG:
$data = $this->getFacebookMessengerData();
break;
case self::EMAIL:
$data = $this->getEmailData();
break;
default:
$data = $this->getData($provider);
}
if($data) {
array_push($result, $data);
}
}
return $result;
}
/**
* @return array|false
*/
protected function getFacebookMessengerData() {
$enabled = $this->getProviderConfig(self::FB_MSG, self::ENABLE);
if($enabled) {
return [
'id' => self::FB_MSG,
'additional' => $this->getProviderConfig(self::FB_MSG, self::APP_ID)
];
}
return false;
}
/**
* @param $provider
* @return array|false
*/
protected function getData($provider) {
$enabled = $this->getProviderConfig($provider, self::ENABLE);
if($enabled) {
return [
'id' => $provider,
'counter' => $this->getProviderConfig($provider, self::COUNTER)
];
}
return false;
}
/**
* @return array|false
*/
protected function getEmailData() {
$enabled = $this->getProviderConfig(self::EMAIL, self::ENABLE);
if($enabled) {
return [
'id' => self::EMAIL,
'additional' => $this->getProviderConfig(self::EMAIL, self::SUFFIX)
];
}
return false;
}
/**
* @param $path
* @return mixed
*/
protected function getConfig($path) {
return $this->scopeConfig->getValue($path);
}
/**
* @param $provider
* @param $config
* @return mixed
*/
protected function getProviderConfig($provider, $config) {
return $this->scopeConfig->getValue(self::SOCIALSHARE. $provider. '/'. $config);
}
}
3. Now we going to modify our resolver and request data from DataProvider
ScandiPWA/SocialShareGraphQl/Model/Resolver/SocialShare.php
<?php
declare(strict_types=1);
namespace ScandiPWA\SocialShareGraphQl\Model\Resolver;
use Magento\Framework\GraphQl\Config\Element\Field;
use Magento\Framework\GraphQl\Query\Resolver\ContextInterface;
use Magento\Framework\GraphQl\Query\ResolverInterface;
use Magento\Framework\GraphQl\Schema\Type\ResolveInfo;
use ScandiPWA\SocialShareGraphQl\Helper\DataProvider;
/**
* @package ScandiPWA\SocialShareGraphQl\Model\Resolver
*/
class SocialShare implements ResolverInterface
{
/**
* @var DataProvider
*/
protected $dataProvider;
/**
* SocialShare constructor.
* @param DataProvider $dataProvider
*/
public function __construct(
DataProvider $dataProvider
) {
$this->dataProvider = $dataProvider;
}
/**
* @param Field $field
* @param ContextInterface $context
* @param ResolveInfo $info
* @param array|null $value
* @param array|null $args
* @return string[]
*/
public function resolve(Field $field, $context, ResolveInfo $info, array $value = null, array $args = null)
{
$result = [
'socialShareConfig' => $this->dataProvider->getSocialShareConfig(),
'providers' => $this->dataProvider->getSocialShareProviders()
];
return $result;
}
}
