The new react-hooks lint rule "Calling setState synchronously within an effect can trigger cascading renders" flagged real anti-patterns in four spots. Refactored each per the rule's intent (derive during render, or use useSyncExternalStore for external subscriptions). 1. hooks/useMediaQuery.ts — replaced the useState + useEffect pair with useSyncExternalStore. That's the canonical React hook for subscribing to external stores (matchMedia in this case) without mirroring into local state via an effect. Snapshot/getServerSnapshot pair preserves the SSR-safe behaviour. 2. components/network/nodes/DeviceNode.tsx — the prop-sync useEffect that copied nodeData.label into labelValue was redundant. labelValue is the EDIT BUFFER; while not editing, the displayed span now reads nodeData.label directly. The buffer is initialized only when an edit session starts (onDoubleClick). 3. components/network/nodes/GroupNode.tsx — same pattern, same fix. 4. components/dashboard/TicketQueue.tsx — the setTickets([]) + setLoading(true) + fetchTickets() chain in the effect was the cascade. Pushed those writes inside fetchTickets (after the function boundary, so they batch with the eventual setTickets(result)). Added a request-id ref so a slow first response can't overwrite a fast second one. Frontend lint: 20 errors → 0 errors. tsc -b clean. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
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:
- @vitejs/plugin-react uses Babel (or oxc when used in rolldown-vite) for Fast Refresh
- @vitejs/plugin-react-swc uses SWC for Fast Refresh
React Compiler
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.
Expanding the ESLint configuration
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// 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,
// Other configs...
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
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 defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Enable lint rules for React
reactX.configs['recommended-typescript'],
// Enable lint rules for React DOM
reactDom.configs.recommended,
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
