  All repositories warning · 1 : warning in React projects

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗

  Render one direct child at a time in mode="wait", or use sync or popLayout when several children can be present.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗

  All repositories error · 1 : error in React projects
  No fix No autofix ↗

  Derive repeated layout IDs from stable item identity, or scope each repeated component with a LayoutGroup ID derived from the item.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/motion-use-transform-range-length

  Use useMotionValue inside React components, or create a manual motionValue outside the render path.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/motion-value-subscription-in-render

  Subscribe with useMotionValueEvent, or create the subscription in an effect and return its cleanup function.

  All repositories error · 1 : error in React projects
  No fix No autofix ↗

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/nextjs-metadata-url-consistency

  All repositories warning · 1 : warning in Next.js projects
  No fix No autofix ↗
• react-doctor/no-access-key

  Do not use accessKey. It conflicts with assistive tech shortcuts.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/no-aria-hidden-on-focusable

  Remove aria-hidden from focusable elements, or stop them being focusable, so keyboard users do not land on content screen readers hide.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/no-arithmetic-on-optional-chained-operand

  An optional chain is undefined when it short-circuits, so *///% on it produces NaN, which silently corrupts formatting and comparisons. Provide a ?? fallback or guard the chain root before the arithmetic.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/no-array-index-as-key

  Use a stable id from the item, like key={item.id} or key={item.slug}. Index keys break when the list reorders or filters.

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/no-assertive-status

  Keep role="status" polite. Use role="alert" only when an interruption is genuinely imperative.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/no-async-effect-callback

  Don't make the effect callback async. Define an async function inside the effect and call it, then return a real cleanup function if you need one.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/no-async-event-handler-without-reentry-guard

  An async onClick/onSubmit handler on a host control that awaits a mutating request and sets state only afterward stays interactive across the await, so a double-click fires the write twice. Add a leading if (busy) return guard, or set a flag before the await inside try and reset it in finally while the control is disabled.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/no-autofocus

  Do not use autoFocus. It disorients users on load.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/no-autoplay-without-muted

  Always pair autoPlay with muted (and playsInline): <video autoPlay muted loop playsInline />. If the sound matters, drop autoPlay and let users start it.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/no-blocked-paste

  Allow paste so people can use password managers, verification codes, assistive tools, and copied text without retyping it.

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/no-collapsed-literal-or-chain-as-value

  Compare against each value separately (or use an array .includes(x)) instead of an all-literal ||/&& chain, which short-circuits to its first literal and drops the rest.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/no-conflicting-spring-options

  Choose either stiffness/damping/mass or duration/bounce for a Motion spring so every configured value takes effect.
