Race conditions in React rarely look dramatic in code review. They show up when an older async result lands after the user has already moved on. This guide gives you a calmer way to fix them.

Server Actions and Route Handlers are both valid tools. The mistake is treating them as interchangeable just because both can write data on the server.

Many React bugs begin when a value that could be derived gets copied into state. The component works for one render path, then starts lying as props and data evolve.

The best form loading state is not the flashiest one. It is the one that keeps users informed, blocks duplicate work, and still makes sense when the form grows more complex.

localStorage bugs in Next.js are usually boundary bugs in disguise. The clean fix is not to sprinkle guards everywhere. It is to make the first render honest.

Optimistic UI feels magical in demos because failure is rare and interruptions are absent. Production is different. The value of useOptimistic depends on what happens when the happy path breaks.

Most App Router fetching bugs are not exotic. They are boundary and intent mistakes that appear again and again under different file names.

Cleanup bugs are easy to postpone because the component looks fine until navigation, remounts, or repeated interactions start stacking hidden work in the background.

Component APIs go wrong slowly. They start with one flexible prop, then another, until the component can technically do everything and explain nothing.

The fastest way to create a fragile App Router codebase is to let every component become half server and half client. This checklist makes the boundary reviewable again.

Hydration errors are usually symptoms, not the root cause. The real problem is unstable output between server render and client boot, and AI-generated code creates that instability fast.

The model changes names and styling, but the underlying mistakes repeat. Once you know the pattern family, AI-generated React diffs become much faster to judge.

AI can draft a believable React diff fast, but it still misses the state ownership and lifecycle details that break real apps. This checklist gives reviewers a narrower, more useful lens.

React 19 gives teams a cleaner escape hatch for stale closures, but only if they stop using effects as a general-purpose patch layer. This guide separates the jobs clearly.

Complex forms tempt developers to reach for a reducer too early. The right choice depends less on field count and more on whether the state transitions need one coherent model.

The fastest way to trust AI-written UI code is not to trust it at all. Start with a small behavior contract, then test the async and state edges the model is most likely to miss.
