const ReactQueryDevtoolsProduction = React.lazy(() => import('@tanstack/react-query-devtools/production').then((module) => ({ default: module.ReactQueryDevtools, })), )

export function LazyDevtools() { return ( <React.Suspense fallback={null}> </React.Suspense> ) }


### Embed a panel

```tsx
import { ReactQueryDevtoolsPanel } from '@tanstack/react-query-devtools'

export function DevtoolsPanel() {
  return <ReactQueryDevtoolsPanel />
}

Use adapter-specific packages

import { ReactQueryDevtools } from '@tanstack/react-query-devtools'
import { VueQueryDevtools } from '@tanstack/vue-query-devtools'

export const devtools = { ReactQueryDevtools, VueQueryDevtools }

Common Mistakes

MEDIUM Eager production devtools

Wrong:

import { ReactQueryDevtools } from '@tanstack/react-query-devtools'

export function AppDevtools() {
  return <ReactQueryDevtools />
}

Correct:

import * as React from 'react'

const Devtools = React.lazy(() =>
  import('@tanstack/react-query-devtools/production').then((module) => ({
    default: module.ReactQueryDevtools,
  })),
)
export function AppDevtools() {
  return (
    <React.Suspense fallback={null}>
      <Devtools />
    </React.Suspense>
  )
}

Production devtools should be lazy-loaded from the production entry.

MEDIUM Mock offline misconception

Wrong:

import { ReactQueryDevtools } from '@tanstack/react-query-devtools'

export function Devtools() {
  return <ReactQueryDevtools initialIsOpen />
}

Correct:

import { onlineManager } from '@tanstack/react-query'

export function setOfflineForTest() {
  onlineManager.setOnline(false)
}

Devtools inspect state; use Query managers or browser tooling to model network state.

HIGH Devtools outside provider

Wrong:

import { ReactQueryDevtools } from '@tanstack/react-query-devtools'

export function Root() {
  return <ReactQueryDevtools />
}

Correct:

import { QueryClient, QueryClientProvider } from '@tanstack/react-query'
import { ReactQueryDevtools } from '@tanstack/react-query-devtools'

const queryClient = new QueryClient()
export function Root() {
  return (
    <QueryClientProvider client={queryClient}>
      <ReactQueryDevtools />
    </QueryClientProvider>
  )
}

Devtools need the same QueryClient context as the app.
