resilient-async-operations

Memory leaks in async operations occur when promises, timers, or event listeners aren't cleaned up after completion or cancellation. This Skill mitigates them through AbortManager for centralized controller lifecycle management, safePromise for error handling, and automatic cleanup on abort or timeout, ensuring resources are released even if operations fail or are cancelled.

Use withTimeout to wrap promises with deadline enforcement and AbortController support, and AbortManager to centralize abort controller creation and cleanup across multiple concurrent requests. This provides graceful timeout handling with automatic resource release and cancellation propagation to dependent operations.

Yes. This Skill is designed for React and UI-heavy projects where component unmounting, effect cleanup, and concurrent API requests need coordinated cancellation. Pair AbortManager with React lifecycle methods or useEffect cleanup functions to prevent state updates on unmounted components and unhandled promise rejections.

safePromise returns [data, error] tuples following Go-style error handling, eliminating try-catch boilerplate and unhandled rejection risks. It pairs with AbortManager and backgroundOperation for consistent, composable error handling across API calls, background tasks, and timeout-wrapped operations in the same codebase.

Use backgroundOperation for fire-and-forget non-blocking tasks where errors should be logged but don't require immediate handling or caller notification. safePromise suits operations where the caller needs explicit error and data results; backgroundOperation suits cleanup tasks, analytics, or logging that must not block the main flow.

No. This Skill has no external dependencies and uses native JavaScript AbortController and Promise APIs available in modern browsers and Node.js. It wraps these built-ins with AbortManager, safePromise, withTimeout, and backgroundOperation to provide structured async patterns without requiring extra libraries.
