Question 1

How to map nested JSON arrays to objects with Valinor?

Accepted Answer

Define classes for each nested level, like the Country and City example in the README, then use the mapper's map() method with the JSON source. Valinor automatically handles recursion based on type hints.

Question 2

Valinor vs Symfony Serializer for API data handling?

Accepted Answer

Valinor excels at strict type safety and validation with static analysis support, while Symfony Serializer offers more customization and framework integration. Choose Valinor for advanced types and clear errors, Symfony for broader ecosystem features.

Question 3

Does Valinor work with PHP 7.4 or only PHP 8?

Accepted Answer

Valinor requires PHP 8.0 or higher for features like attributes and improved type system, as indicated by the PHP version requirement in the README. It leverages modern PHP capabilities for better performance and type handling.

Question 4

How to handle custom validation logic beyond types in Valinor?

Accepted Answer

Valinor focuses on type validation; for custom rules, you may need to pre-process data or extend the mapper with custom modifiers, as it doesn't include a built-in rule engine like some validators.

Question 5

Can Valinor normalize objects to CSV files directly?

Accepted Answer

Yes, the normalization mechanism can output objects as CSV, but you might need to configure aspects like headers and delimiters manually, as detailed in the documentation for advanced use cases.

Question 6

Is Valinor suitable for high-traffic web applications?

Accepted Answer

While Valinor ensures data integrity, its reflection-based mapping can add latency. For high-traffic apps, consider caching mapped objects or profiling performance, as the overhead might be significant in critical paths.
