In April 2025, Narek Galstyan developed a custom InstantAPIError class for the instantdb/instant repository, focusing on standardizing API error handling in TypeScript. By introducing this centralized error class, he enabled promises to be rejected with structured, detailed error information, which improved stack trace clarity and debugging efficiency. His work emphasized consistent error propagation and clearer API failure responses, enhancing both reliability and developer experience for client integrations. Leveraging skills in API integration and error handling, Narek concentrated on maintainable patterns and documentation, delivering a single, well-scoped feature that addressed error consistency without introducing new bug fixes during the period.
