SYSTEM DOCUMENTATION & REQUIREMENTS

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.

FAQPage Schema

How do I fix race conditions in React useEffect when fetching data with Zustand?▼

Race conditions in React useEffect with Zustand occur when overlapping async requests resolve out of order. You can fix them by enforcing correct async patterns, adding proper cleanup logic, and validating post-conditions before applying state updates to prevent UI inconsistencies.

What is a floating promise in React and how do I detect it?▼

A floating promise in React is an asynchronous call that fires and is forgotten without awaiting or returning. Detect floating promises by analyzing Zustand actions and component callbacks to identify unhandled executions, ensuring you apply proper awaits or returns to prevent silent failures.

How do I handle sequential vs parallel async execution in Zustand actions?▼

Handling sequential vs parallel async execution in Zustand actions requires deciding when tasks must complete in order versus when they can run concurrently. You should analyze your async flows to structure execution correctly without compromising data fetching correctness or causing race conditions.

Can I use this approach to debug async timing issues in React Native as well as web?▼

Yes, you can debug async timing issues in React Native as well as web applications. The analysis applies to data fetching and state updates across web and native React codebases using Zustand to identify missing awaits, floating promises, and race conditions.

Why does my Zustand store update with stale data after an async fetch?▼

Your Zustand store updates with stale data after an async fetch due to missing awaits or floating promises that allow subsequent code to execute prematurely. You can resolve this by enforcing post-condition validation and ensuring critical async results are verified before proceeding.
