Hello Magento Folks 👋,
Welcome to Magento 2 How-To blog series by MageComp. Today’s article describes Magento 2: Add Swatch Data in Layered Navigation Aggregations in GraphQL. Not to miss out on our previous blog, Magento 2: How to Get System Configurations Value in Email Templates.
Swatch data comes to help in increasing the shopping experience of your store and let the user purchase with ease from your store. Providing the option of swatching data, the user can select color, size, and other options for a particular product just by selection instead of reloading the page. Magento 2 offers adding swatch data in layered navigation aggregations in GraphQL. The query searches for the products that match the specified search criteria.
Let’s get started 🚀
Step 1: Create file app/code/VENDOR/EXTENSION/registration.php and add the following code:
|
1 2 3 4 5 |
use Magento\Framework\Component\ComponentRegistrar; ComponentRegistrar::register( ComponentRegistrar::MODULE, 'VENDOR_EXTENSION', __DIR__); |
Step 2: Create file app/code/VENDOR/EXTENSION/etc/module.xml and add the following code:
|
1 2 3 4 5 6 7 8 9 10 |
<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd"> <module name="VENDOR_EXTENSION" setup_version="1.0.0"> <sequence> <module name="Magento_Store"/> <module name="Magento_Catalog"/> <module name="Magento_CatalogInventory"/> </sequence> </module> </config> |
Step 3: Create file app/code/VENDOR/EXTENSION/etc/schema.graphqls and add the following code:
|
1 2 3 4 5 6 7 8 9 |
interface AggregationOptionInterface { swatch_data: SwatchData @doc(description: "Data required to render swatch filter item") } type SwatchData { type: String @doc(description: "Type of swatch filter item: 1 - text, 2 - image") value: String @doc(description: "Value for swatch item (text or image link)") } |
Step 4: Create file app/code/VENDOR/EXTENSION/etc/graphql/di.xml and add the following code:
|
1 2 3 4 |
<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd"> <preference for="Magento\CatalogGraphQl\DataProvider\Product\LayeredNavigation\LayerBuilder" type="VENDOR\EXTENSION\DataProvider\Product\LayeredNavigation\DataProviderAggregationPlugin"/> </config> |
Step 5: Create file app/code/VENDOR/EXTENSION/DataProvider/Product/LayeredNavigation/DataProviderAggregationPlugin.php and add the following code:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 |
