SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Solve memory leaks and unstable UI caused by abandoned promises in JavaScript/TypeScript applications.

Core Features & Use Cases

  • AbortManager: Centralized abort controller management with automatic cleanup.
  • safePromise: Go-style error handling returning a [data, error] tuple.
  • backgroundOperation: Non-blocking tasks that log errors without crashing the UI.
  • withTimeout: Timeout-wrapped promises with abort support.

Quick Start

Create an AbortManager and wire your async tasks through safePromise and withTimeout to manage cancellation and timeouts.

FAQPage Schema
How do I fix memory leaks from abandoned promises in React applications?

Handle abandoned promises with Go-style error handling that returns a tuple. This pattern separates execution success from failure, letting you manage async errors without try-catch blocks and safely resolve or reject API calls.

What is the best way to add a timeout to a long-running API call in JavaScript?

Add a timeout to long-running API calls by wrapping promises with timeout and abort support. This ensures background tasks automatically cancel if they exceed the specified duration, preventing unresponsive interfaces.

Can I run background tasks in TypeScript without crashing the UI on errors?

Run background tasks without crashing the UI using non-blocking operations that automatically log errors. This isolates async task failures from the main interface, keeping your application stable during long-running background processing.

Do I need external libraries to manage async cancellation and retry logic in JavaScript?

You do not need external libraries to manage async cancellation and retry logic. This approach provides modular utilities built from native JavaScript features to handle timeouts, error handling, and abort controllers without dependencies.
