What's New

StreamedCSVResponse (#12)

New StreamedCSVResponse class for large CSV exports without memory buffering. Extends Symfony's StreamedResponse and writes rows directly to php://output.

// Stream large datasets without hitting memory limits
return new StreamedCSVResponse($data);

// Works with callables for lazy data loading
return new StreamedCSVResponse(function () {
    return $repository->findAllAsGenerator();
});

Shared architecture

• Extracted CSVResponseInterface with shared constants
• Extracted CSVResponseTrait with shared logic (value conversion, formula sanitization)
• CSVResponse refactored to use interface + trait — zero BC break
• Both classes now accept callable data sources (in addition to iterable)
