Émile Ré f98b73f073 Upgrade frontend toolchain to latest majors
Bump React 19.2, Relay 21, React Router 8, Vite 8 with
@vitejs/plugin-react 6, ESLint 10, GraphQL 17, TypeScript 6,
@types/node 24, and Tailwind 4.3 across the workspaces.

vite-plugin-react 6 (Vite 8) no longer runs Babel, so the Relay
tagged-template transform now runs through @rolldown/plugin-babel
in the console and trust Vite configs.

Relay 21 ships first-party types and enables the ambiguous-alias
check by default; disable that flag to preserve existing queries
and add explicit usePreloadedQuery type arguments where the new
types no longer infer the operation. TypeScript 6 deprecations and
stricter inference are addressed in tsconfigs and call sites.

Keep n8n-node on ESLint 9 and eslint-plugin-react on 7.37.5, the
newest releases compatible with their toolchains.

React + TypeScript + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:

export default tseslint.config({
  extends: [
    // Remove ...tseslint.configs.recommended and replace with this
    ...tseslint.configs.recommendedTypeChecked,
    // Alternatively, use this for stricter rules
    ...tseslint.configs.strictTypeChecked,
    // Optionally, add this for stylistic rules
    ...tseslint.configs.stylisticTypeChecked,
  ],
  languageOptions: {
    // other options...
    parserOptions: {
      project: ['./tsconfig.node.json', './tsconfig.app.json'],
      tsconfigRootDir: import.meta.dirname,
    },
  },
})

You can also install eslint-plugin-react-x and eslint-plugin-react-dom for React-specific lint rules:

// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'

export default tseslint.config({
  plugins: {
    // Add the react-x and react-dom plugins
    'react-x': reactX,
    'react-dom': reactDom,
  },
  rules: {
    // other rules...
    // Enable its recommended typescript rules
    ...reactX.configs['recommended-typescript'].rules,
    ...reactDom.configs.recommended.rules,
  },
})
