Pagerfanta adapter for Doctrine PHPCR-ODM, enabling paginated results from PHPCR document queries. Integrates Pagerfanta with PHPCR-ODM query builders/documents so you can build pagers and render page links efficiently.
Pagerfanta adapter for Doctrine PHPCR ODM
Frequently asked questions about Doctrine Phpcr Odm Adapter
- How do I install this Pagerfanta adapter for Doctrine PHPCR ODM in Laravel?
- Install via Composer with `composer require pagerfanta/doctrine-phpcr-odm-adapter`. Ensure you already have `doctrine/phpcr-odm` and `pagerfanta/pagerfanta` installed. The adapter integrates seamlessly with existing PHPCR ODM setups, so no additional Laravel service provider or configuration is required beyond standard PHPCR ODM initialization.
- Does this work with spatie/laravel-phpcr-odm?
- Yes, this adapter is fully compatible with `spatie/laravel-phpcr-odm`. Since spatie’s package abstracts Doctrine PHPCR ODM for Laravel, you can use this adapter directly with their document repositories. Just ensure your PHPCR ODM is properly configured before initializing Pagerfanta.
- What Laravel versions does this package support?
- This adapter is framework-agnostic and works with any Laravel version that supports Doctrine PHPCR ODM. However, it assumes your Laravel app is using PHP 7.4+ and Doctrine PHPCR ODM v3+. Check the adapter’s [GitHub repository](https://github.com/Pagerfanta/doctrine-phpcr-odm-adapter) for exact compatibility notes, as it depends on upstream Pagerfanta and PHPCR ODM versions.
- Can I use this for client-side pagination (e.g., infinite scroll) in Laravel?
- Yes, this adapter supports client-side pagination by fetching only the required subset of documents for each page. Pagerfanta’s abstraction layer makes it easy to implement infinite scroll or lazy-loading patterns. However, ensure your PHPCR repository supports efficient range queries, as deep offsets may impact performance.
- What if my PHPCR repository doesn’t support LIMIT/OFFSET efficiently?
- If your PHPCR backend (e.g., Jackrabbit or Squirrel) lacks efficient pagination support, consider using Pagerfanta’s `CursorPaginator` or implementing a keyset-based approach. The adapter itself doesn’t enforce a specific pagination strategy, so you can customize it based on your repository’s capabilities. Test performance with large datasets to identify bottlenecks.
- Is there a way to test pagination edge cases like empty results or large offsets?
- Yes, you can test edge cases by mocking the PHPCR ODM repository in your unit tests. Use PHPUnit to verify behavior with empty result sets, large offsets, or malformed queries. Pagerfanta provides built-in methods to check for empty pages, so integrate those into your test suite. For performance, benchmark queries with realistic dataset sizes using tools like Blackfire or Xdebug.
- Can I use this adapter alongside Eloquent in a hybrid Laravel app?
- Absolutely. Since Pagerfanta is a generic pagination library, you can use this adapter for PHPCR ODM while leveraging Pagerfanta’s Eloquent adapter for relational data. This unifies pagination logic across your hybrid stack. Just ensure your Laravel app initializes both adapters separately and manages their dependencies explicitly.
- What are the performance implications of using this adapter in production?
- This adapter reduces memory usage by fetching only paginated results, which is critical for large PHPCR datasets. However, performance depends on your PHPCR backend’s query capabilities. Avoid deep offsets (e.g., page 1000) if your repository doesn’t optimize range queries. For better performance, consider indexing frequently queried document properties or using Pagerfanta’s cursor-based pagination.
- Are there alternatives to this adapter for PHPCR pagination in Laravel?
- If you’re not tied to Pagerfanta, you could implement custom pagination using PHPCR ODM’s native query builder with `findBy()` and manual offset/limit logic. However, this lacks Pagerfanta’s abstraction and features like page links or cursor support. For Laravel-specific solutions, explore `spatie/laravel-query-builder` extensions, though they don’t natively support PHPCR.
- How do I handle maintenance if this package or Pagerfanta stops being updated?
- Since this is a thin adapter layer, you can fork the repository and maintain it yourself if upstream packages stagnate. Pagerfanta is widely used, so breaking changes are rare. For long-term stability, consider contributing to the project or monitoring its GitHub activity. If Doctrine PHPCR ODM or Pagerfanta introduces breaking changes, the adapter’s simple design makes it easier to update than a monolithic solution.
