You can use tools like GraphQL IDL or GraphQL Java to define your schema.Next, you can use a GraphQL client library like GraphQL Java to send GraphQL queries and mutations to your API. This library allows you to build and execute GraphQL queries using Java code.

For example, if we have a query for retrieving information about a user, we can pass parameters such as the user's ID or username by specifying them within parentheses after the field name. These parameters can then be accessed within the resolver function of the corresponding field to fetch the relevant data.

7 min readTo migrate existing stored procedures to use GraphQL, you will need to first understand the data schema and operations currently defined in the stored procedures. Next, you will need to create a corresponding GraphQL schema that represents the same data structure and operations. You may need to modify the existing stored procedures to return data in a format that can be easily consumed by GraphQL, such as JSON.

This flag is used to ensure that cookies are only accessible through HTTP requests and cannot be accessed through client-side scripts.To enable the http only flag, you need to locate the "httpd.conf" file in your XAMPP installation directory. This file can typically be found in the "conf" folder within the Apache installation directory.Once you have located the "httpd.

5 min readTo get the GraphQL schema in TypeScript, you can use a tool like graphql-codegen which allows you to generate TypeScript types from your schema. This tool will analyze your schema and generate typescript types for all your queries, mutations, and subscriptions. This way, you can have type-safe code when working with GraphQL in your TypeScript projects.

5 min readTo pass a hash as an argument in a GraphQL mutation, you can simply define the argument in the mutation schema with the type of the hash object. You can then pass the hash as an argument when making the mutation request. The hash argument can be of any complex type, such as an object, array, or JSON string. In the resolver function for the mutation, you can access the hash argument just like any other argument passed to the mutation.

5 min readTo implement GraphQL sub-queries, you can simply nest the desired sub-fields within the parent field in your GraphQL query. This allows you to retrieve nested data in a single query, making your application more efficient and reducing the number of round trips to the server.For example, if you have a user object that contains a list of posts, you can fetch both the user information and their posts in a single GraphQL query by specifying the sub-fields within the 'user' field.
