5 min readYou can find the XAMPP default 404 page files in the "htdocs" directory of your XAMPP installation. The specific file is typically named "404.html" or "404.php" and can be customized or replaced with your own design or content. This page is displayed whenever a user tries to access a page on your server that does not exist. Make sure to update and personalize this file to provide a better user experience when your visitors encounter a 404 error.

5 min readTo give Gatsby a GraphQL schema, you first need to define your data sources and create nodes for each piece of data you want to query. This process involves setting up plugins such as gatsby-source-filesystem or gatsby-source-graphql to fetch data from various sources like local files or external APIs.Next, you will need to customize the schema by using the createSchemaCustomization API in your gatsby-node.js file.

5 min readIn GraphQL, parameters can be passed to a function by defining them in the query fields within curly braces after the field name. 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.

4 min readTo create a virtual host in XAMPP on Windows 7, you need to first open the XAMPP control panel and click on the "Apache" button to open the Apache configuration file (httpd.conf). In this file, you need to uncomment the following line by removing the "#" symbol: "Include conf/extra/httpd-vhosts.conf"Next, locate and open the "httpd-vhosts.conf" file in the "extra" folder of the XAMPP installation directory.

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.

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.

6 min readIn GraphQL, you can log successful requests by implementing middleware or hooks that capture and record relevant information about each successful request. This can include details such as the query or mutation being executed, the user making the request, and any relevant metadata.One common approach is to create a custom middleware function that is executed before or after each request is processed by the GraphQL server.
-
7 min readTo apply auth middleware to a GraphQL endpoint, you can add the middleware function to the resolver function that handles the incoming requests to the endpoint. This middleware function can check the authorization token provided in the request headers and verify if the user is authenticated before allowing the resolver to execute. This way, you can ensure that only authorized users can access the GraphQL endpoint and its data.
-
4 min readTo get the count of the id field from a table using GraphQL, you can define a query that retrieves the total number of records in the table by performing a query on the GraphQL server. You can use a GraphQL query language to specify the fields you want to retrieve, including the count of the id field. You can then send this query to the server and receive the count of the id field in the response.
-
6 min readTo create a delete mutation in GraphQL, you need to follow these steps:Define a new type for the delete input, which typically includes an ID field representing the entity to be deleted.Create a new mutation in your schema definition with a name that reflects the action being performed (e.g., "deleteEntity").Add arguments to the delete mutation that correspond to the input fields defined in step 1.Implement the resolver function for the delete mutation in your server code.

8 min readTo connect MongoDB with GraphQL without using Mongoose, you can utilize the MongoDB Node.js driver along with a GraphQL server like Apollo Server or GraphQL Yoga.First, you would need to establish a connection to your MongoDB database using the MongoDB Node.js driver. You can create a new instance of MongoClient and use the connect method to connect to your database.Once your connection is established, you can define your GraphQL schema using the type definitions and resolvers.
