Introduction to Laravel API Development: Lesson 7 - Pagination and Filtering

Welcome to the seventh lesson of the "Introduction to Laravel API Development" course! In this lesson, we'll dive into the topics of pagination and filtering in your Laravel APIs. You'll learn how to efficiently manage and present large sets of data in your API responses.

Pagination When dealing with large datasets, it's important to implement pagination to split the data into smaller chunks or pages. This improves the performance of your API and provides a better user experience.

Laravel offers built-in support for pagination using the paginate method.

$items = Item::paginate(10); // Retrieve 10 items per page

Filtering Filtering allows users to narrow down the data they retrieve from your API. You can implement filtering by accepting query parameters in your API endpoints and using them to modify your database queries.

public function getItems(Request $request)
{
    $query = Item::query();

    if ($request->has('category')) {
        $query->where('category', $request->input('category'));
    }

    $items = $query->get();

    return response()->json($items);
}

Combining Pagination and Filtering You can combine pagination and filtering to provide users with paginated results based on their specified filters.

Your Task: Implement Pagination and Filtering For this lesson's assignment, implement pagination and filtering in your API endpoints. Choose one of the endpoints you've created and modify it to support pagination and filtering.
