SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Frontend polling can end up in an endless loading state when background tasks crash, time out, or fail to write results. This Skill enforces a robust pattern that guarantees terminal task states are persisted to the database, ensuring the UI can stop polling and render a proper outcome.

Core Features & Use Cases

  • Persist terminal states for all background tasks (completed or failed).
  • Use a safe wrapper to guarantee a database write even when the task encounters errors.
  • Enable frontend polling to reliably react to 'completed' or 'failed' states and surface results or errors.

Quick Start

Configure your safeBackgroundTask wrapper to always persist the task state and update the frontend polling to react to 'completed' or 'failed' states.

Frequently Asked Questions about Async Background Task Error Handling

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
Why does frontend polling get stuck in an endless loading state for background tasks?▼

Frontend polling gets stuck in an endless loading state when background tasks crash, time out, or fail to write results to the database, leaving the UI without a terminal state to react to.

How do I persist terminal states for long-running background tasks?▼

Persist terminal states by applying a safe runner wrapper around background tasks, guaranteeing a database write of either completed or failed states even when the task encounters unexpected errors.

What is the best way to handle errors in async data scraping and batch processing?▼

The best way to handle errors in async data scraping and batch processing is wrapping the task in a safe runner that guarantees the error is persisted to the database, enabling the frontend to render the failure.

How do I stop frontend polling when an async background task fails?▼

Stop frontend polling by configuring the UI to react to persisted 'failed' or 'completed' states in the database, guaranteeing the polling loop terminates and surfaces the proper error or result.

Does this background task error handling pattern work for AI generation workflows?▼

Yes, this pattern works for AI generation workflows by applying schema design, a safe runner wrapper, and frontend polling to guarantee visible completion or failure states across frontend-backend boundaries.

When should I not use polling for background task management?▼

Polling becomes unreliable for background task management when tasks crash without persisting terminal states, making a safe wrapper that guarantees database writes necessary before polling can be safely implemented.
