Error Handling Patterns

Implement centralized Express error middleware to catch Remotion rendering failures, wrapping rendering and bundling steps in try-catch blocks with precise failure reporting to ensure consistent JSON error responses and guaranteed resource cleanup.

Retry failed S3 uploads using exponential backoff logic combined with safe cleanup procedures. This pattern progressively retries failed storage operations while maintaining clean resource management across development and production environments.

Custom error classes like RenderError and ValidationError model specific failure stages in your rendering workflow. They enable centralized Express error middleware to distinguish between validation failures and rendering issues, producing uniform JSON error responses.

Stream error progress to clients by implementing Server-Sent Events (SSE) error streaming in your Express application. This pattern safely shares rendering progress and failure states, allowing centralized middleware to format clear JSON errors for client-side handling.

Yes, this error handling pattern explicitly supports both development and production environments. It applies structured cleanup logic and centralized error middleware across API routes, Remotion rendering workflows, and S3 storage operations regardless of the environment.
