What problem does it solve?

Async bugs in React with Zustand are subtle and can slip past tests, including race conditions, missing awaits, and floating promises that cause UI inconsistencies.

Core Features & Use Cases

• Floating Promise Detection: identify calls that fire-and-forget and ensure proper awaiting or returns.
• Post-Condition Validation: verify critical async results before proceeding and throw helpful errors when checks fail.
• Async Function Identification: surface hidden async patterns in Zustand actions or callbacks.
• Sequential vs Parallel Async: decide when to run tasks in sequence or in parallel without compromising correctness.
• Async in useEffect: enforce correct patterns for effectful async operations and avoid memory leaks.
• ESLint & best practices: enforce no-floating-promises, require-await, and proper promise handling.

Quick Start

Inspect a React component that uses Zustand to fetch data and fix missing awaits and race conditions.
