Magento2 - GraphQL Schema to fetch Custom Table data

Magento2 an open-source e-commerce platform written in PHP.

GraphQL a new approach to working with APIs. It is a data query language developed by Facebook. It was implemented by Adobe Commerce and Magento Open Source to provide an another approach to REST and SOAP web APIs for frontend development.

Basically, GraphQL is a query language for APIs which gives clients the power to ask for exactly the need and nothing more. GraphQL uses mutations to perform CRUD operations.

While working in the Magento2 site let's say for an example there is a need to create a custom forms or save some data for client. In order to fulfill this need & pass this custom data via GraphQL we have created a custom module.

In order to achieve this we are first going to create a simple Magento2 module. We already have a custom table named bookfreemeasure with filled in form data(you can select you own custom table). Form this table we are going to fetch users information like firstname, lastname & email.

   

Installation Steps

Step 1 : Download the Zip file from Github & Unzip it

Step 2 : Create a directory under app/code/Binstellar/Freehomemeasure

Step 3 : Upload the files & folders from extracted package to app/code/Binstellar/Freehomemeasure

Step 4 : Go to the Magento2 Root directory & run following commands

php bin/magento setup:upgrade

php bin/magento setup:di:compile

php bin/magento setup:static-content:deploy -f

php bin/magento cache:flush

   

Important Note

• Please change & add you factory method under Binstellar\Freehomemeasure\Model\Resolver\DataProvider\Bookfreemeasure

   

Note : We have tested this option in Magento ver. 2.4.5-p1

   

Verification of the GraphQL. For this you can use Altair GraphQL or ChromeiQL extensions.

To check this query we need to set up the endpoint which usually goes like    

<magento_root_url>/graphql
