Mastering Pagination with Rebing Laravel GraphQL

When developing modern web applications, providing users with a streamlined experience is paramount. This often includes the ability to efficiently handle large sets of data, particularly when displaying it in a format like a table. For applications built with Laravel as a backend and ReactJS as a frontend, implementing pagination in your GraphQL queries becomes essential.

The Problem: Pagination in GraphQL

In the scenario described, the user is attempting to return paginated data using the Rebing GraphQL library in Laravel. This library allows for smooth JSON data retrieval, similar to traditional Blade methods but can sometimes exhibit unexpected behavior—in this case, when using the paginate method.

Key Issues Faced:

Despite using the paginate method, the user received the same data format as the get method.

The expectation was to receive a full pagination structure (such as currentPage, nextPage, etc.), similar to the behavior of the LengthAwarePaginator class.

The Solution

To resolve the issue of obtaining paginated data in the desired format, the solution lies in modifying the return type of your GraphQL query. Here's a breakdown of how to effectively implement pagination in your GraphQL setup using the Rebing library.

Step 1: Adjust the Return Type

Instead of simply returning a list of items, you need to specify the paginated response format. This can be achieved with the following change:

Step 2: Modify Your Query

Next, update your query structure to leverage the new pagination type. Here’s how you can structure your GraphQL query:

Explained Fields:

data: An array that contains the paginated items (e.g., year models).

total: The total number of items available.

per_page: How many items are shown on each page.

current_page: The current page number being viewed.

from: The index of the first item on the current page.

to: The index of the last item on the current page.

last_page: The total number of pages available.

has_more_pages: A boolean indicating if there are additional pages to view.

Step 3: Utilizing getPaginationFields

The above fields are derived from the getPaginationFields method of Rebing\GraphQL\Support\PaginationType. By utilizing this method, the paginated response can be structured effectively to provide all the essential pagination details.

Conclusion

Implementing pagination in a Rebing Laravel GraphQL server not only enhances the user experience but also improves the performance of your application. By adapting your query’s return type and utilizing the built-in pagination methods, you can deliver comprehensive data to your ReactJS frontend.

This approach makes working with large datasets manageable and allows users to navigate through content seamlessly.

Understanding these steps will undoubtedly make you more proficient in using GraphQL with Laravel and will enhance the capabilities of your web applications. Happy coding!
