Original Pull Request: https://github.com/langgenius/dify/pull/30279

State: closed
Merged: Yes

Summary

This PR migrates the frontend devtools from the standalone @tanstack/react-query-devtools integration to the official unified TanStack Devtools container and optimizes development tools loading for production performance.

Changes

🔧 Architecture & Migration

  • Dependencies: Modified web/package.json to include @tanstack/react-devtools and @tanstack/react-form-devtools.
  • New Component: Introduced web/app/components/devtools.tsx containing the TanStackDevtoolsWrapper.
  • Integration: Updated web/context/query-client.tsx to use the new wrapper component.

⚡ Performance & Tree-Shaking

  • TanStack Devtools: Implemented lazy loading (React.lazy) and dynamic imports in query-client.tsx, ensuring devtools code is completely tree-shaken and excluded from production bundles.
  • React Scan: Refactored static import in web/app/layout.tsx to use next/dynamic with ssr: false. This ensures React Scan is only loaded in the browser during development, further reducing the initial bundle size.

Verification

  1. Run pnpm dev in the web directory.
  2. Open the application.
  3. Verify the TanStack logo appears in the bottom-right corner.
  4. Verify React Scan functionality (if enabled).
  5. (Advanced) Run a production build (pnpm build) and verify that neither TanStack Devtools nor React Scan code is included in the main bundles.
